Using Google Earth API to find the structure of a landscape

I am looking to use the Google Earth API to hel开发者_如何学运维p one of my robots navigate around big obstacles (such as buildings).

Is there any way to get information on the structure of buildings/features (such as trees) that Google Earth renders through the Javascript API?

I think you can achive this via hit-testing - the GEHitTestModeEnum GEPlugin.HIT_TEST_BUILDINGS may be suitable for your needs - although the actual accuracy in the real world may not be high enough for you. Calculating a 'buffer zone' around you robot would be the best bet.

Here is the GEView hit-test documentation

Here is a working hit-test example.
