Online databases such as MySQL and PostgreSQL are very popular for storing large amounts of data online, including geometry fields for storing points, lines and areas. Google has recently launched an online database like product called Fusion Tables which allows one to store large amounts of data in the cloud, analyse the data, link it to other tables, etc. Some really powerful features include viewing the data on a map, charting, views, and export to KML for integration with map products. Until recently one was only able to display point based data using a latitude and longitude coordinate pair, or by geocoding placenames on the fly.

As of this week one is also able to import KML data which represents the different vector formats, points, lines, polygons. This means that Fusion Table's storage can be used for storing large GIS datasets, analyse them (based on attributes) and output them to different map products. See a quick example below of some admin boundaries for Kenya which I imported. 

I will explore these new exciting features more in the (holidays) coming days and show more of what is possible.
