add DTM in Google Earth

[xinhua]

Hello, friends:
I have a big digital terrain model (DTM) with high resolution (1m grid). Does anybody know how to add my own DTM in Google Earth?

Thanks a lot.

Hi xinhua,

Google Earth uses the Collada interchange file format for its 3D models. The best thing to do is look at the KML 2.1 Tutorial and go to the section Importing 3D Models for details on how to do this.

Google Earth is not able to load terrain data from a file. If you convert it to Collada, it will draw the geometry of terrain on top of whatever existing terrain there is, but it won't drape the imagery on top of you data.

Someday.

How about bathymetry?
