Javascript blog CMS : blogger




To build any webpage on internet there are three most important languages viz. HTML, JavaScript and CSS. JavaScript is one of the most commonly used client-side programming language that may communicate asynchronously (i.e. independently of other processes) to web browser.

If you are using BlogSpot.com blogger blog then you have lots of option to include JavaScript codes. It will depends on where you want to render it and for which purpose you are using that JavaScript files or codes.

See this present "ex-ample" blog.

The top 10 ways to embed Google Earth content (trails, footpaths, interactive guide to fishing, walking, biking) on your site blog (special mention to blogger) with or without earth plugin and with/without earth API

A) without coding (no javascript)
3 categories of methods: without the need of plugin install (Google Earth plugin, for browsers) and without the google earth API or with this API (in this case, the client must install the  Google Earth plugin)

A-a) without the need of Google Earth plugin
A-b) without the google earth API 
A-c) with the google earth API 

B) with coding (javascript)

-----------------------------------------------
-----intro (not necessary if you just want a one-click service to directly embed in your site)

The Google Earth plug-in allows you to navigate and explore geographic data on a 3D globe using a web browser: http://www.google.com/earth/explore/products/plugin.html
If you want to embed the Google Earth plug-in on your website, visit the Google Earth API site to learn more: http://code.google.com/apis/earth/
Check out the recently revamped (2011) Earth API Developer's Guidehttp://code.google.com/apis/earth/documentation/

This plugin and this API may work correctly on all browsers (Internet Explorer 7.0+, mac and PC: Firefox 3.0+; Google Chrome 5.0+; Safari 3.1+, etc...) that support NPAPI with npruntime extensions (https://developer.mozilla.org/En/Gecko_Plugin_API_Reference:Scripting_plugins).
Plugins (or plug-ins) are shared libraries that users can install to display content that the application itself can't display natively. For example, Adobe Reader plugin (or Google earth plugin) lets the user open PDF files directly inside the browser. Plugins are written using NPAPI, the cross-browser API for plugins: https://developer.mozilla.org/en/Plugins

To install the Google Earth Plugin, browse to any page in which the plugin is included or at http://www.google.com/earth/explore/products/plugin.html (at this URL, you can see the version of your plugin).

This plugin and this API offer many services, see these 2 "ex-amples" (trail):
(google maps and google earth and a path from one start address and one end address)
http://www.themountainpulse.com/trail-maps-plus/grand-teton-national-park/ (The Mountain Pulse is an online resource for Jackson Hole’s outdoor community: mountain biking, hiking, pathways cycling, fishing, kayaking, lodging and more)

---after this intro, let's start!
from http://code.google.com/apis/earth/documentation/

To load the Google Earth Plugin in your web page, you need to:
  1. Load the Google Earth API.
  2. Create a DIV element to hold the plugin.
  3. Create functions to initialize the plugin.
  4. Call the initialization functions once the page has loaded.
try the hello: http://code.google.com/apis/ajax/playground/?exp=earth#hello,_earth



A) without coding (no javascript)


A-a) without the need of Google Earth plugin


A-b) without the google earth API 

A-c) with the google earth API 



B) with coding (javascript)

SVG, Scalable Images, not JPG, GIF or PNG in Blogger blogspot

Questions about a recent post containing a couple of flow charts made me regret the fact that 


Blogger does not support SVG graphics by direct insertion :
You may upload multiple files at once but you can only use JPG, GIF, or PNG files.
  
Although I made the charts using the excellent TiKZ LaTeX package (which produces vector output in the form of a PDF file), I had to convert the PDF output to PNG for Blogger, and the images are a tad fuzzy (and do not scale well when zoomed), which may have led to some confusion. So I was on a mission today to find a workaround.

The first thing I discovered that SVG is not nirvana.  I generated the images as separate PDF files from the TiKZ source.  (Hint to people doing this: use the LaTeX standalone document class and the output file will automatically be cropped to the smallest rectangle containing the image.)  I then used ImageMagick to convert the PDF files to SVG files ... which blew them up from around 54 KB to about 8+ MB. Each. Oops!  
I tried a tool I found to convert the SVG files to "canvas" files, which got me another 5x or so increase in size.  So back to PDF files.  


Blogger does not consider PDFs to be images, to the plan now is to use a PNG file as the image and link it to the corresponding PDF, allowing readers to click on the image and at least get a scalable version in a new window or tab.

Blogger does not allow you to upload arbitrary files, only images in formats it recognizes (which are actually stored in Picasa, another Google product/Web-service). I thought about putting the PDFs on a personal server somewhere, but I worry about moving things (including them) to a new server at some future date and not remembering to update the links.  Enter Google Documents.  I just have to upload the PDFs to Google Docs, make them public, grab the URLs and set the links on the PNGs (which by default point to the PNG files in Picasa) to point to the PDFs in Google Docs instead.

Spherical harmonics, meshes and some WebGL and JavaScript : toxiclibs.js, Processing.js, Three.js, ThreeNodes.js



1--------Spherical Harmonics Mesh Builder

Spherical Harmonics Mesh Builder is an example of Paul Bourke's "spherical harmonics" function for creating organic meshes. This example shows the use of Toxiclibs.js for creating meshes inside Three.js
(Technology: JavaScript, WebGL, toxiclibs.js, three.js).

Spherical harmonics are the angular portion of a set of solutions to Laplace's equation. Spherical harmonics are important in many theoretical and practical applications, particularly in the computation of atomic orbital electron configurations, representation of gravitational fields, geoids, and the magnetic fields of planetary bodies and stars, and characterization of the cosmic microwave background radiation. In 3D computer graphics, spherical harmonics play a special role in a wide variety of topics including indirect lighting (ambient occlusion, global illumination, precomputed radiance transfer, etc.) and recognition of 3D shapes.
The 19th century development of Fourier series made possible the solution of a wide variety of physical problems in rectangular domains, such as the solution of the heat equation and wave equation. This could be achieved by expansion of functions in series of trigonometric functions. Whereas the trigonometric functions in a Fourier series represent the fundamental modes of vibration in a string, the spherical harmonics represent the fundamental modes of vibration of a sphere in much the same way.
is called a spherical harmonic function of degree ℓ and order m.
For a given value of ℓ, there are 2ℓ+1 independent solutions of this form, one for each integer m with −ℓ ≤ m ≤ ℓ. 

Toxiclibs.js is an open-source computational design library ported to javascript by Kyle Phillips originally written by Karsten Schmidt for Java and Processing. Examples of the original library can be found at http://toxiclibs.org

Toxiclibs.js works great with Canvas, with SVG or any ordinary DOM element. with Processing.js, Three.js, or Raphael.js for SVG...

great example with additive waves

3--------three.js
JavaScript 3D library
The aim of the project is to create a lightweight 3D library with a very low level of complexity — in other words, for dummies. The library provides , and WebGL renderers.

--ThreeNodes.js
Threenodes.js is an attempt to create a dataflow environment in javascript and html5. It's a way to see what is possible to do in the browser. I had a little list of interesting javascript libraries to try but never had the chance to play with them.

The project is still in an experimental state but you can already see a live demo there: http://idflood.github.com/ThreeNodes.js/
coffeescript, compass and haml
These are languages that compile to javascript, css and html. Their syntax are much shorter than their equivalent and they offer some great features. If you work a lot with js, css or html you should definitely check these.
http://jashkenas.github.com/coffee-script/
http://compass-style.org/
http://haml-lang.com/
Three.js
The project is using webgl to render the scene. Three.js was obviously the 3d engine of choice. It provide many features like shaders, geometries, postprocessing filters and so on. A great project :)
https://github.com/mrdoob/three.js/
node.js
This is a javascript server. It's used to automatically compile the source files and serve them. I could have used some simple bash script to compile the files but found it would be interesting to use this for this "node" based project.
http://nodejs.org/
Require.js
The application was quickly growing and I needed a way to make it more modular. It's still not used at his full potential in threenode.js but already help make the code cleaner. One nice feature is that it's possible to require text files, or in this case little html template files.
http://requirejs.org/
--------------
Processing.js is the sister project of the popular Processing visual programming language, designed for the web. Processing.js makes your data visualizations, digital art, interactive animations, educational graphs, video games, etc. work using web standards and without any plug-ins. You write code using the Processing language, include it in your web page, and Processing.js does the rest. It's not magic, but almost.

Molecular visualization Off-Line and On-Line : spiderGL, a JavaScript 3D Graphics library which relies on WebGL for realtime rendering

http://spidergl.org/index.php

VERY GOOD.
Try it online or download the zipped archive (an HTTP server is needed):


2/ Visualization Methods for Molecular Studies on the Web Platform

http://vcg.isti.cnr.it/Publications/2010/CADZS10/



Standard representation of molecular surface properties using color ramps and field lines (leftmost), the same properties drawn using complex shading techniques (center) and the electrical interaction of two proteins (rightmost), rendered on a Web Page by using SpiderGL and WebGL.


Molecular visualization Off-Line and On-Line


The solution of the 3D structure of myoglobin in 1958 by Kendrew [Kendrew et al. 1958] marked the beginning of the new era of protein structural biology. Since then, a large number of protein structures have been solved and today the Protein Data Bank counts over 60.000 entries [Berman et al. 2003]. With the availability of all these data and the advance of computer graphics technologies, many research groups have developed tools for the manipulation and visualization of 3D structures such as VMD [Humphreyet al. 1996], SPDBViewer [Guex and Peitsch 1997], Chimera [Pettersen et al. 2004] and PyMOL [Delano 2002]. Beside working on the atomic structure, most programs can nowadays also calculate surface features such as electrostatic potential (using, for example, tools like APBS [Baker et al. 2001] or DelPhi [Rocchia et al. 2002]) and hydropathy [Kyte and Doolittle 1982].

In addition to the many standalone visualization tools, there are also web viewers especially designed for molecular structures, such as Jmol [jmo 2002] and MDL Chime, which represent a simple way
to visualize molecules directly on browser. MDL Chime, used by the Protein Explorer website was gradually phased out in favor of Jmol, which is nowadays the most used plugin for molecular visualization, used by websites such as Proteopedia and RCSB PDB Protein Data Bank.
Following the advance of techniques for the generation of CG movies, in the last few years many different groups focused on the creation of animated movies depicting biological molecules and
cellular processes. The movies range from the simple representations of the mechanical functioning of a single protein, to complex events involving many subjects. These works are important scientific efforts and add to their educational value the bonus of rising interest in the general public to approach biology. Some of these examples are collected on websites [McGill 2010; SCIVIS 2005].

3D Content on Web



The Virtual Markup Modeling Language (VRML) [Raggett 1994] (then replaced by X3D [Don Brutzmann 2007]) was proposed as a text based format for specifying 3D scenes in terms of geometry and material properties and for the definition of basic user interaction. The format itself was a standard, but the rendering in the web browser was relaying on specific plugins. The Java Applets are probably the most used method to add dynamic content, not necessarily 3D, in the web browsers. The
philosophy of Java applets is that the URL to the applet and its data are put in the HTML page and then executed by the Java Virtual Machine, a third part component. The implementation of JVM
on all the operating systems made Java applets ubiquitous and the introduction of binding to OpenGL such as JOGL [JOG ] added control on the 3D graphics hardware. A similar idea lies behind the
ActiveX [Microsoft Corporation 1996] technology, developed by Microsoft from 1996. Unlike Java Applets, ActiveX controls are not bytecode but dynamic linked Windows libraries which share
the same memory space as the calling process (i.e. the browser), and so much faster to execute. These technologies enable the incorporation of 3D graphics in a web page but they all do it by handling
a special element of the page itself with a third party component.


WebGL [Group 2009b] is an API specification produced by the Khronos group [Group 2009a] and, as the name suggests, defines the JavaScript analogous of the OpenGL API for C++. WebGL
closely matches OpenGLjES 2.0 and, extremely important, uses GLSL as the language for shader programs, which means that the shader core of existent applications can be reused for their
JavaScript/WebGL version. Since WebGL is a specification, it is up to the web browsers developer to implement it. At the time of this writing, WebGL is supported in the nightly build versions of the most used web browsers (Firefox, Chrome, Safari), and a number of JavaScript libraries are being developed to provide higher level functionalities to create 3D graphics applications. For example WebGLU [DeLillo 2009], which is the WebGL correspondent of GLU [OpenGL ARB ], provides wrappings for placing the camera in the scene or for creating simple geometric primitives, other libraries such as GLGE [Brunt 2010] or SceneJS [Kay 2009] uses WebGL for implementing a scene graph based rendering and animation engines.

Implementation spiderGL


Looking at a webpage with dynamic SpiderGL content, it is possible to see that all of the page logic is defined in the scripting part of the HEAD section, while on the BODY section there is just the page
structure and the interface elements that will be used for user interaction (like buttons, text areas and other controls). Among these elements, the most important is an html canvas object, that is the place where the WebGL layer does the on-screen rendering. ("< " are transformed : "[")

[canvas id="SGL_CANVAS" style="border: 1px solid gray"  width="900" height="600"][/canvas]



This canvas is registered as the output area at the end of the scripting; a specific function connects the various events of the canvas to a script object.


v a r  glMolViewer = new SpiderGLMolViewer ( ) ;
sglRegisterCanvas("SGL_CANVAS" , glMolViewer , 3 0 . 0 ) ;




The glMolViewer object is the main actor for the scene setup and rendering of our molecular visualization. The structure of this object employs the event handling subsystem provided by SpiderGL, which is inspired from the one used by the GLUT library [Kilgard ]. Each event coming from the canvas triggers a specific function with a given name and parameters; SpiderGL exploits the JavaScript language feature to give the possibility to dynamically add or remove listeners and redirect events. In this simple example, the only listener is the main object itself. (...)

This development process is straightforward for someone with an experience in graphical programming, while may prove to be difficult for users with a different background, like biology, physics or chemistry. This kind of setup is for sure more difficult to master with respect to setup of other existing platforms, like Jmol which, true to their nature, provide much simpler (but restrictive) access to their scene graph, with specific functions to import data and a series of predefined rendering modes. However, the gain in terms of flexibility and expressive power vastly compensate the initial steeper learning curve. Moreover, the learning of this technology is made easier by the possibility of initially use the higher level structures and functions implemented by SpiderGL to easily setup a basic visualization scheme and then start playing with lower level functions to obtain more complex effects. It is also important to note that most of the available JavaScript utility/UI libraries on the net may be used in conjunction with SpiderGL, adding more ready-made components to assemble a powerful, interactive, webpage.

google maps, fractals; fractal renderer in HTML 5; it is now possible to render in a browser fractals like Julia sets almost instantly;

Google launched (Jan 2011)  Julia Map on Google Labs, a fractal renderer in HTML 5. Julia sets are fractals that were studied by the French mathematician Gaston Julia in the early 1920s. Fifty years later, Benoît Mandelbrot studied the set z2 − c and popularized it by generating the first computer visualisation. Generating these images requires heavy computation resources. Modern browsers have optimized JavaScript execution up to the point where it is now possible to render in a browser fractals like Julia sets almost instantly.

Julia Map uses the Google Maps API to zoom and pan into the fractals. The images are computed with HTML 5 canvas. Each image generally requires millions of floating point operations. Web workers spread the heavy calculations on all cores of the machine.

We hope you will enjoy exploring the different Julia sets, and share the URLs of the most artistic images you discovered. See what others have posted on Twitter under hashtag #juliamap. Click on the images below to dive in to infinity! (Supported on Chrome 8, Firefox 3.6, Safari 5 and above).

case study: Europe, US and "e-trailblazing" services; list kml tourism file; wikipedia and long-distance paths (LDP); LDP's database; walking, trek, trekking, hiking, rambling, bushwalking, mountain climbing; tracks, line, routes; guidebook;

How to Create a Better Trail Map?
The goal of this post is a brief screening of different approaches about e-services for searching/publishing walking, trek, trekking, hiking, rambling, bushwalking, mountain climbing...
IN RED: my best choices

http://ex-ample.blogspot.com/2011/08/geo-content-management-system.html


see one of my blog (in french) for micro-local geo-WebServices : http://la-loire.blogspot.com/
There are some of my javascripts...


It is an example of the complex aggregator services.
We have to aggregate SEVEN components of this "GIS-social-geocoding-web mapping": 
A) The global maps/routes/directions SERVERS (http://ex-ample.blogspot.com/2011/08/comparison-of-maps-servers-and-their.html; google maps, Bing Maps, Map Quest, Maps Nokia; Open Street Map) allow 4 services:
  1.  online view/manipulate your map/directions (and print)
  2. "save/open" with an URL
  3. "save" with an iframe (HTML)
  4. "save/open" with  HTML+javascript codes (or other "languages" flash, silverlight, javaME...)
Local maps cover only part of the earth surface, and may be more detailed than the global ones:
http://en.wikipedia.org/wiki/List_of_online_map_services


B) We have many geographic information systems software, 
http://en.wikipedia.org/wiki/Comparison_of_geographic_information_systems_software
C) We have many GIS products (GPS, cell phones, cam/apparatus with automatic or semi-automatic geo tag, meteo/climate systems, ...) 
D) geography is a social science then there are many complex metadata. There are a lot of personal pages/sites/blog relating a trek.
E) we already have excellent guidebooks then e-guidebooks must be better or offer different services...
F) official websites: official paths (national and regional) and funded trails organizations
G) laws, all approaches for preserving the natural resources...


-----------
The problem of interoperability is THE big problem of web 2.0 applications/services with User Generated Content, not only in GIS-geocoding-web mapping... (just the routes, no problem: GPX or KML files, but the main problem is all other aspects of a route (culture, point of interest...)
Participatory GIS  is an emergent practice; developing out of participatory approaches to planning and spatial information and communication management. Traditional knowledge GIS could help in debates over land rights and resource management in ecologically sensitive areas. Interests of local residents in these regions often conflict with those of migrant workers, state conservation units, and domestic and foreign mining or logging enterprises.
example: http://www.openstreetmap.org/ (http://en.wikipedia.org/wiki/OpenStreetMap) or WikiMapia (http://www.wikimapia.org/; WikiMapia API: http://www.wikimapia.org/api/) is a online map imaging resource that combines Google Maps with a wiki system (mainly POI and a few trails).
http://wikimapia.org/special_pages/user_reports/?action=show&type=1&id=209&backurl=%26type%3D%26order%3D%26p%3D5

Goodchild, M.F. (2007). "Citizens as sensors: the world of volunteered geography". GeoJournal 69 (4): 211–221; DOI: http://dx.doi.org/10.1007%2Fs10708-007-9111-y
Volunteered Geographic Information is the harnessing of tools to create, assemble, and disseminate geographic data provided voluntarily by individuals. Sites such as Wikimapia and OpenStreetMap are empowering citizens to create a global patchwork of geographic information, while Google Earth and other virtual globes are encouraging volunteers to develop interesting applications using their own data. I review this phenomenon, and examine associated issues: what drives people to do this, how accurate are the results,will they threaten individual privacy, and how can they augment more conventional sources? I compare this new phenomenon to more traditional citizen science and the role of the amateur in geographic observation.

Here i try to show how this problem is complex with an "ex-ample" (case study): management, organization, sharing, writing collaborative e-handbook of walking, trek, trekking, hiking, rambling, bushwalking, mountain climbing... Definition of trek: http://oxforddictionaries.com/definition/trek


The question is how to perform "e-trailblazing" with the best collaborative content management and multipath/pointOfInterest saving/searching/publishing?

There are many methods used for blazing trails http://en.wikipedia.org/wiki/Trail_blazing. Moreover blaze type might also be mixed when different user groups (horse riders, mountain bikers, snowmobilers...) are on the same trail.
There are many methods used for e-trailblazing: compare the choice of french GR (Long Distance Footpaths Network)  http://www.gr-infos.com/gr-en.htm and the choice of german Long Distance Footpaths Network http://www.wanderbares-deutschland.de/ and the excellent choice of the UK Searchable LDP's Database http://www.ldwa.org.uk/ldp/members/ldp_members_home.php.

The guidebooks are still the best way to prepare a Long or One-day Distance Footpaths. They contains not only the path/elevation data/maps but also many metadata (tourisme, guesthouse, shelders, laws, toilets (in urban trip), prices of parcs, museum...). Everytrail offers many e-guides (Mobile Travel Guides): http://www.everytrail.com/guides
try these three guides in Paris (only 3; DATA @ august 2011), availables for iphone and android:

-------------Europe; differences between states 
In Europe (http://www.era-ewv-ferp.com/) there are many differences of this "geo-social domain".
 for european long-distance trails, see http://www.era-ewv-ferp.com/?page_id=29 and "wikipedia" below.

France has an extensive network of footpaths throughout the country. More than 60000 km of long distance footpaths and 120000 km of local footpaths have been created with IGN maps and many guidebooks. The Fédération Francaise de la Randonnée Pédestre (FFRP) is the organization behind the long distance footpaths - les sentiers de grande randonnée (GR) which exist all over the country (see below).
FFRP, representing 1600 walking clubs, publishes more than 150 guidebooks (topoguides des sentiers de grande randonnée).
It has standardized guidebooks and trailblazing (white-redmarked trail):  http://www.ffrandonnee.fr/_130/le-balisage-des-itineraires-de-randonnee.aspx (only in french).

some sites:

Germany : the Verband Deutscher Gebirgs- und Wandervereine – Deutscher Wanderverband - is the organization of almost 56 large associations.
only in german: on the website http://www.wanderbares-deutschland.de/ 90 among the most outstanding paths  in Germany are described in detail (with google maps API). VERY GOOD SITE (but no collaborative functions). You can find all necessary information at a glance: a path description, its length and height profile, maps of single routes as well as the addresses of the competent tourist organizations and ramblers’ associations...

Great Britain:
England and Wales have 225 000 Km (140,000 miles) of off-road routes classed as Public Rights of Way. These are short local off-road routes that everyone has a right to use even where they cross private land, and they are protected by local authorities (although some of them may be illegally blocked). They should be signed at junctions with public roads. Many are also signed or "waymarked" with coloured arrows along the route itself. Footpaths are open only to walkers, and may be waymarked with yellow arrows. In addition to rights of way, where you only have a right to walk along the path itself, there are over 1.4 million ha of "access land" where you have a right to walk freely. This land is mainly open country: mountain (over 600m), moor, heath, down and common land. The exact areas covered are shown on official maps.
Scotland has a general right of access to most land, even farmland, so long as you behave responsibly.
Recognised signed recreational paths and trails (including long distance paths), have developed rather differently in Britain than in many other European countries, partly because walking organizations have historically campaigned for more general local access rights. The Long Distance Walkers Association keeps records of all trails over 30 Km long, and documents these in 2 publications, The Long Distance Walker’s Handbook and The Long Distance Path Chart.
National Trails (the best maintained trails in England and Wales) have special legal status and receive funding from central government agencies.  They are signed with an acorn logo.  There are 15 such trails with a total length of 4000 Km. Scotland’s Great Trails are a suite of 20 nationally promoted longer distance routes in Scotland. Each of these trails is individually waymarked, and collectively branded with the thistle logo.  They extend to over 2000 Km.

Belgium: there is a network of long distance footpaths, covering the whole country 5000 km white-redmarked trails exist. Parts of these are extensions of the border- crossing GR 5 and GR 12 (see France). Guidebooks (topogidsen in Flemish and topoguides in French) can be ordered from Grote Routepaden (http://www.groteroutepaden.be/) and Sentiers de Grande Randonnée (S.G.R.; http://www.grsentiers.org/) which are responsible for the network of footpaths in Flanders and Wallonia respectively.

Netherlands: a network of more than 35 long distance footpaths (from 60 to 400 Km). The total network is more than 6000 km. Some of the paths are long distance footpaths (lange- afstand wandelpaden) and others are regional (streekpaden). In cooperation with the organisation which coordinates these footpaths (wandelplatform), Dutch Rail has developed a number of daytrips (and some trips for 2 days) going from station to station.
In guides with maps (1:25000), all practical information is given. They are easy to use even if you do not know Dutch: there is a special section with essential topics explained in English.

In the United States agencies administering trails include the National Park Service, the U.S. Forest Service, the Bureau of Land Management, State Park systems, County Parks, cities, private organizations such as land trusts, businesses and individual property owners.
New trail construction by an agency must often be assessed for its environmental impact and conformance with State or Federal laws. For example, in California new trails must undergo reviews specified by the California Environmental Quality Act.

Information about the draft Federal Trail Data Standard:
http://www.fgdc.gov/standards/projects/FGDC-standards-projects/trail-data-standard/public-review-Federal-Trail-Data-Standard/?searchterm=trail
The functional scope of the draft Federal Trail Data Standard (FTDS) includes the definition of a core set of trail data attributes, corresponding values, and definitions. This draft standard reflects tabular and spatial trail data applicable. The draft Federal Trail Data Standard does not cover all possible trail data or agency-specific data needs, but concentrates on a core set of inter-jurisdictional management and administrative trail data needs. The FTDS are not a database (this effort does not create any new databases.  For the first time, four federal land management agencies (BLM, FWS, NPS and USFS) have collaborated to standardize their definitions of commonly used trail terminology). Data collection and implementation schedules will be determined by each agency.  The FTDS simply provide common definitions and terminology for a core set of trail information. The FTDS do not include standardized data definitions for facilities or “things along the trail”. This level of detail is beyond the scope of the FTDS and more appropriate for individual agencies or entities to define, depending on their specific data needs. 
The federal trail data standard (sept 2010; trails of all kinds):
http://www.fgdc.gov/standards/projects/FGDC-standards-projects/trail-data-standard/Federal_Trail_Data_Standards_20100909HS.pdf
Projection: NAD83 is the national standard.


Definition of Trail:  A linear route managed for human-powered, stock, or off-highway vehicle forms of transportation or for historic or heritage values.

Trail Code Trail Category:
  1. Reg. Trail : Regular Trail: any agency-managed trail not designated NST or NHT
  2. NST: National Scenic Trail (Congressionally Designated)
  3. NHT1 (Desig): Route(s) congressionally designated as the National Historic Trail
  4. NHT2 (HR): NHT associated heritage resources (routes and/or sites)
  5. NHT3 (Rec): NHT associated recreation or interpretive route and/or site
The metadata must be in a FGDC-compliant format (for both spatial and non-spatial data) as 
documented at http://www.fgdc.gov/metadata/geospatial-metadata-standards


The creation of the National Spatial Data Infrastructure (NSDI) was authorized by President Clinton under Executive Order 12906 in 1994, and has provided the policy umbrella for geographic information in the US : http://www.fgdc.gov/nsdi/nsdi.html
In the mid 1990s the U.S. Federal Geographic Data Committee published its Content Standards for
Digital Geospatial Metadata, a format for the description of geographic data sets. The project was very timely, given the rapid increase in the availability of geographic information via the Internet that occurred at that time. Metadata were seen as the key to effective processes of search, evaluation, and use of geographic information. Nevertheless, and despite numerous efforts and inducements, it remains very difficult to persuade those responsible for creating geographic data sets to provide adequate documentation. (GeoJournal (2007) 69:211–221)
The Bureau of Land Management (BLM; http://www.blm.gov/wo/st/en.html) is an agency within the United States Department of the Interior which administers America's public lands, totaling approximately 1,023,855 km2 (one-eighth of the landmass of the country). The BLM also manages 2,832,800 km2 of subsurface mineral estate underlying federal, state and private lands. Its budget is US$960,000,000 for 2010 ($9.38 per hectare). The BLM also manages 7200 km of National Scenic, Historic, and Recreational Trails, as well as thousands of km of multiple use trails used by hikers, equestrians, motorcyclists and mountain bikers.

----China
In 1999, the inaugural International Symposium on Digital Earth in Beijing provided a venue for the extensive international support for implementing the Gore Digital Earth vision (1998).
An explosion of Chinese "Digital Earth" projects followed: hundreds of digital earth cities created by national, provincial, and municipal governments as well as universities.
In China, "Digital Earth" and GIS became a metaphor for modernization and automation with computers, leading to its incorporation into a five-year modernization plan.
Originating from China’s satellite remote sensing community, Digital Earth prowess spread to a range of applications(flood predictions, dust cloud modeling, and city planning). China has been omnipresent at all international Digital Earth conferences since and has recently founded the International Society for Digital Earth. In 2009, the International Symposium on Digital Earth returned to Beijing for its 6th meeting.

Proceedings / Volume 7492 / Multi-sensor, Multi-resolution, and Multi-mode Data Fusion
The travel craze in China has become one of the largest sources of expenditure increases. However, the limited patterns of information demonstration hindered the availability of necessary information to the public as well as the decision makers. Google Earth provides a useful platform for integrating environmental information with geospatial data from different sources. Using KML files, various environmental data may be viewed in Google Earth. In this paper, Google Earth is used as basic GIS platform. Placemarks of main tourist areas of Hubei Province are made and loaded by KML. The most up-to-date information is released using text, picture and video in HTML files. This approach transformed the traditional two-dimension travel information system into multi-dimensional information platform, facilitating data updating and information sharing over the Internet. It would also help decision making of the government and promote information availability to the public.

Proceedings / Volume 7840 / Web-based Services, System Design, and Algorithms for Digital Earth
In recent years national parks worldwide have introduced online virtual tourism, through which potential visitors can search for tourist information. Most virtual tourism websites are a simulation of an existing location, usually composed of panoramic images, a sequence of hyperlinked still or video images, and/or virtual models of the actual location. As opposed to actual tourism, a virtual tour is typically accessed on a personal computer or an interactive kiosk. Using modern Digital Earth techniques such as high resolution satellite images, precise GPS coordinates and powerful 3D WebGIS, however, it's possible to create more realistic scenic models to present natural terrain and man-made constructions in greater detail. This article explains how to create an online scientific reality tourist guide for the Jinguashi Gold Ecological Park at Jinguashi in northern Taiwan, China. This project uses high-resolution Formosat 2 satellite images and digital aerial images in conjunction with DTM to create a highly realistic simulation of terrain, with the addition of 3DMAX to add man-made constructions and vegetation. Using this 3D Geodatabase model in conjunction with INET 3D WebGIS software, we have found Digital Earth concept can greatly improve and expand the presentation of traditional online virtual tours on the websites.

---------my best choice:

KML and Fusion Table
Fusion Tables supports visualizing your data on maps (it is a better alternative to Spreadsheet Mapper:
http://earth.google.com/outreach/tutorial_fusion_yourowndata.html#comparemappers).

see the example : Biking and Hiking trails from MTBGuru.com 
http://www.mtbguru.com/ alexa rank: 1450000 (DATA@august 2011).

http://blog.mtbguru.com/2010/02/24/mtbguru-tracks-as-seen-through-google-fusion-tables/
It's a cloud-based collaborative database application. To illustrate these fusionTable features, data from MTBGuru (public trips) have been used to demo these visualizations. Some maps show tracks from public trips in the map area, which are all overlayed as polylines. Moreover the polylines are clickable and will show you an infoWindow with links to the original trip page. The data, which lives in a Fusion Table, can be filtered and manipulated as one can expect in a database environment, and the visualization will be adjusted accordingly. See the data: http://www.google.com/fusiontables/DataSource?dsrcid=132848
They have created a Google Code project with sample code illustrating how we used the API to work with Fusion Tables and create the table with trips: http://code.google.com/p/mtbguru-fusiontables/, see updated project: https://github.com/tokumine/fusion_tables (this gem lets you easily interact with Google Fusion Tables API from your Ruby application via a plain SQL interface, or an object orientated interface). See also this example (position of bikes, London: http://www.google.com/fusiontables/DataSource?snapid=78314)

Fusion Tables supports a number of data formats:
Comma-separated files (.csv) - Up to 100 MB
Microsoft Excel files (.xls, .xlsx) - Up to 1 MB
OpenDocument Spreadsheet (.ods) - Up to 1 MB
Keyhole Markup Language (.kml) - Up to 100 MB
Data already in a Google Spreadsheet
If you have datasets in Excel or Open Office Spreadsheets that are larger than 1MB, save them as CSV files to take advantage of the larger 100MB limit!

-------see a good example (trail and many menus on the map):
 http://www.mappingsupport.com/p/gmap4.html

Gmap4 map displaying information from a delimited text file.This new file format is much easier to understand than GPX or KML files.

--------at the end of this post, the last but not the least:
the dotted lines (one dotted lines or parallel dotted lines, in black; see the images below) of the IGN map or "carte France raster" correspond to paths, footpaths, mule track, hiking trail, nature trail, beaten track....Many of them have no trailblazing. Some of these "dot lines" correspond to old paths and you must need a sickle ;)
The parallel //dotted lines corresponds to "roads" for farm tractor or 4X4 (without asphalt): non-motorized trails. There is no difference (same dotted lines) for the two types of trails - paved (bicycle) and unpaved hiking trails.


select IGN map with scale 1:64000, you can see many tourism POI http://www.ign.fr/institut/documentArticle.do?idDoc=6152265&indexRoot=4&indexChild=2&currentRootSearch=&indexChildSearch=
Select some maps with national/regional  parks and biodiversity data: http://www.geoportail.fr/5061756/actu/6026212/carte-sur-la-biodiversite.htm
Select the "land parcels" layer, you will see "barbed wires";)

Yahoo: no direct right click!
When you create a waypoint, it is difficult to drag it!
