Create simple DEM from Google Map

With texture support in Mathematica 8.0, we can create the simple DEM with image overlay by combing the functions from two previous posts Google Static Map and Google Elevation API.

 googleDEM

However, there is the usage limits on Google Elevation API. You’d better pull the dem once and export the data, otherwise, you may hit the daily limits very quickly.

Here is an example on displaying earthquake data with the dem, the red line outlines the fault plane.

Thanks for the info, I never realized that google offered its elevation data as an API. I am working on a wetland mapping project and automatically went to download the DEM. Thanks for the info.
