Our latest project is a 'proof of concept' that it is possible to place 1000's of locations on one Google Map. So we thought it would be interesting to try and start a directory of geo-tagged locations under different categories and sub-categories, e.g Buildings - skyscrapers, castles, churches etc.
The idea is to build a directory of locations that can be easily navigated. The map is at an early stage of development. There are currently just over 1000 locations mapped in a few categories. The plan is to build a directory of tens of thousands of locations under hundreds of categories.
The map at the moment is called the Satellite View Directory - please remember it is at an early stage of testing.
