Buildings, Collada models
Display houses and buildings available in the Collada format.
Notes:
More efficient then direct support for Collada format would be to convert the models in advance into JSON files:
http://code.google.com/p/o3d/wiki/ColladaConverter

The initial implementation should probably load the model and locate it in a correct place on Earth programmatically.
For efficient displaying of whole town composed of larger amount of models a server side preprocessing or dynamic streaming must be implemented - with several level of details (generalized version of model for distant view, detailed for close view once it is loaded).
I we need something like: http://www.youtube.com/watch?v=rGLInTXTdNI#t=07s…

Display terrain (elevation, geometric height, DTM): mountains, etc.
Visualize 3D terrain instead of the sphere only.
Note: this involves preparing and hosting of a separate tileset which will represent the geometric height by the values of pixels (greyscale). Triangles in the WebGL Earth can be then adjusted by the relevant height (pixel value) loaded from the texture (tile) at given lat/lon position.
Possible datasets to use:
- GTOPO30: global digital elevation model (DEM) ~ 1km x 1km - http://eros.usgs.gov/#/Find_Data/Products_and_Data_Available/gtopo30_info
- SRTM3: Shuttle Radar Topography Mission ~ 90m x 90m - http://www2.jpl.nasa.gov/srtm/
- CGIAR: 90m
