Google earth GEOdata?

Question: Is it possible to use/retrieve Geodat开发者_JAVA技巧a from Google-Earth ?

What I want to do is take a little area, get terrain information (coordinates, height, elevation) and simulate how the selected area would be flooded at specified amounts of rain for a specified amount of hours.

Free terrain data for specified areas can be retrieved from NASA's SRTM mission, which used radar mapping from the space shuttle. I think Google Earth uses this same data.
