Some popular file formats:
Latitude and longitude are expressed in decimal degrees using the WGS 84 datum. Elevation is recorded in meters. Dates and times are not local time, but instead are Coordinated Universal Time (UTC) using ISO 8601 format.

-geoJSON
The GeoJSON format specification was finalized in June 2008.
http://en.wikipedia.org/wiki/GeoJSON
http://geojson.org/geojson-spec.html
GeoJSON is a geospatial data interchange format based on JavaScript Object Notation (JSON).
In fact, every GeoJSON data structure is also a JSON object, and thus JSON tools can also be used for processing GeoJSON data.
http://www.geowebguru.com/articles/97-technical-overview-geojson
JavaScript Object Notation (JSON), and the terms object, name, value, array, and number, are defined in IETF RTC 4627, at http://www.ietf.org/rfc/rfc4627.txt
http://en.wikipedia.org/wiki/JSON
JSON is simply a mixture of JavaScript object and array literals without variable definitions.
JSON, is a text-based open standard designed for human-readable data interchange. It is derived from the JavaScript scripting language for representing simple data structures and associative arrays, called objects. Despite its relationship to JavaScript, it is language-independent, with parsers available for most languages.The JSON format is used primarily to transmit data between a server and web application (serving as an alternative to XML; it is generally more compact than XML).
Spatial data format types supported in GeoJSON include points, polygons, multipolygons, features, geometry collections, and bounding boxes, which are stored along with feature information and attributes. The geometries and their properties will have a parent object.
GeoJSON also allows specifying a geographic coordinate system, using the OGC crs (coordinate reference system) property (preferred) or with an EPSG code. If a crs is not defined, GeoJSON will use the WGS84 geoid by default.
GeoJSON is supported by numerous mapping and GIS software packages. Google maps, google maps api...use JSON
-geoRSS
http://en.wikipedia.org/wiki/GeoRSS
http://www.georss.org/Main_Page
As RSS and Atom become more prevalent as a way to publish and share information, it becomes increasingly important that location is described in an interoperable manner so that applications can request, aggregate, share and map geographically tagged feeds.
There are currently two encodings of GeoRSS, Simple and GML (GeoRSS Geography Markup Language (GML)):
GeoRSS-Simple is meant as a very lightweight format that developers and users can quickly add to their existing feeds. It supports basic geometries (point, line, box, polygon) and covers the typical use cases when encoding locations.
GeoRSS GML is a formal GML Application Profile, and supports a greater range of features, notably coordinate reference systems other than WGS-84 latitude/longitude.
Both formats are designed for use with Atom 1.0, RSS 2.0 and RSS 1.0.
Blogger and geoRSS: http://bloggerindraft.blogspot.com/2008/12/new-feature-geotagging.html
-XML: SVG - Scalable Vector Graphics is an XML format. I think that this file format must be in this GIS list because may map servers use this format and all modern browsers use this format.
http://www.mccurley.org/svg/
http://en.wikipedia.org/wiki/File:USA_Oregon_location_map.svg
http://commons.wikimedia.org/wiki/Category:SVG_maps
better SVG graphics rendering engine: http://antigrain.com/svg/index.html
(MapServer 5.0+ can use this engine; it supports sub-pixel anti-aliasing, as well as many more features).
look also the "svg" category of this blog ;)
-XML-based interchange format: GPX or GPS eXchange Format
GPX – XML-based interchange format
http://en.wikipedia.org/wiki/GPS_eXchange_Format
It describes waypoints, tracks, and routes.
A collection of points (with no sequential relationship) is deemed a collection of individual waypoints.
An ordered collection of points may be expressed as a track or a route. Tracks are a record of where a person has been (with timestamp (because someone is recording where and when they were there)) and routes are suggestions about where you might go in the future...
View the official site: http://www.topografix.com/gpx.asp
-XML-based interchange format: KML
KML – Keyhole Markup Language, XML-based
http://en.wikipedia.org/wiki/Keyhole_Markup_Language
The KML file specifies a set of features (place marks, altitude, images, 3D models, polygons, textual descriptions, camera view...). Each place always has a longitude and a latitude.
KML files are distributed in KMZ files, which are zipped files with a .kmz extension.
http://schemas.opengis.net/kml/2.2.0/
reference: http://code.google.com/apis/kml/documentation/kmlreference.html
Developer's Guide: http://code.google.com/apis/kml/documentation/topicsinkml.html
http://kml-samples.googlecode.com/svn/trunk/interactive/index.html
Google Maps supports the following KML elements (that is, KML queries in the Search box and GGeoXml objects in the Maps API):
- Placemarks
- Icons
- Folders
- Descriptive HTML
- Entity replacement via
and - KMZ (compressed KML, including attached images)
- Polylines and polygons
- Styles for polylines and polygons, including color, fill, and opacity
- Network links to import data dynamically
- Ground overlays and screen overlays
This list does not apply to Google Earth's export to Google Maps, My Maps import, or My Maps export to Google Earth.
differences between maps and earth for KML: http://code.google.com/apis/kml/documentation/kmlelementsinmaps.html
Maximum uncompressed KML file size=10MB.
Maximum number of Network Links=10.
convert GIS data to KML files
You can import GIS Data and file (ESRI Shape, MapInfo .tab data; GeoTIFF, or other raster dataset) into Google Earth Pro so that it can be used as part of your Google Earth visualizations: http://earth.google.com/outreach/tutorial_importgis.html. If you have Google Earth Pro, you can import many kinds of GIS data directly using the methods described in this tutorial. If you are using the free version of Google Earth, there are other tools for converting GIS data to KML.
ESRI ArcGIS and MapInfo, have tools to export GIS data into KML format (for use in Google Earth).
ogr2gui (http://sourceforge.net/projects/ogr2gui/): a free utility that converts many formats, including shapefiles to KML.
shp2kml (http://www.zonums.com/shp2kml.html): a free utility that converts shapefiles to KML.
MapWindow GIS has Shape2Earth (http://shape2earth.com/default.aspx), a tool for converting GIS data to KML.
ESRI ArcGIS contains tools in the ArcToolbox (Conversion Tools > To KML) for converting vector and raster GIS data to KML.
Arc2Earth (http://www.arc2earth.com/) is an extension for ArcGIS that converts GIS data to KML. The Arc2Earth Community Edition (http://www.arc2earth.com/communityedition/) is a free tool that has lower limits than the full version.
MapInfo Professional has a MapInfo Professional Google Earth Link Utility: http://mapinfo-to-google-earth-tm-export-utilit.software.informer.com/

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!
Manage your Data with Open Data Kit Aggregate:
http://earth.google.com/outreach/tutorial_odk_aggregate.html
Open Data Kit (ODK) is a suite of tools that allows data collection using mobile devices and data submission to an online server, even without an Internet connection or mobile carrier service at the time of data collection. Once you've collected data in the field with ODK Collect, you can upload and manage your data using ODK Aggregate. ODK Aggregate is the intermediary server storage platform that accepts the data and can send it on to external applications, if desired. ODK Aggregate also allows you to download your datasets in aggregated formats, such as one .csv file. ODK Aggregate allows you to use Google's AppEngine hosting platform (see many post of this blog) for managing your collected data online.
