Google Fusion Tables and geospatial data; managing-and-visualizing-your-geospatial-data-with-fusion-tables

Google Fusion Tables (https://www.google.com/fusiontables) is a modern data management and publishing web application that makes it easy to host, manage, collaborate on, visualize, and publish data tables online. Fusion Tables allows for import of geospatial data to quickly and easily display that data on a Google Map.

The Fusion Tables team has been working hard to enrich what Fusion Tables offers for customization and control of the Google Map visualizations. Two very exciting announcements were made at Google I/O during the Fusion Tables session on Managing and visualizing your geospatial data with Fusion Tables (http://www.google.com/events/io/2011/sessions/managing-and-visualizing-your-geospatial-data-with-fusion-tables.html). These announcements include the release of the Info Window and Styling in the Fusion Tables API and Fusion Table Styling in the Google Maps API.


Fusion Tables Styles in the Google Maps API

Fusion Tables Styles further increases the possibilities of map customization. Rather than applying a style to a table via the API or UI, styling can now be introduced on the client side using the Google Maps API. There are many benefits to Fusion Tables Styles:
It allows for dynamic styling of map features.
It’s opens up the possibility for styling tables with multiple attributes.
You can give your users the opportunity to decide what range of styles works best for your data.
Third party developers can now generate visualizations of your data that differ from your own, which makes sharing your data more powerful and useful.
Fusion Tables styles are available now! Read more about how to use Fusion Tables Styles in the Fusion Tables Layer section (http://code.google.com/apis/maps/documentation/javascript/overlays.html#FusionTables) of the Google Maps API documentation.

Simon Rogers, who joined us for the Fusion Tables I/O session to talk about how the UK Guardian Datablog uses Fusion Tables, has been making great use of Fusion Tables Styles.
Here’s one of the Guardian’s latest examples (http://www.guardian.co.uk/news/datablog/interactive/2011/jun/30/uk-population-mapped).
If you’re interested in creating a map similar to the Guardian’s, we have developed a template for plug-and-play (http://gmaps-samples.googlecode.com/svn/trunk/fusiontables/dynamic_styling_template.html).
