I have had some great success using the KML "Generate Super Overlays" to create tiles of imagery that can be easily viewed using Google Earth.

 

 

Now I would like to go the next step and show my DEM information textured with the imagery also in KML using Google Earth. I can certainly generate a KML file with the DEM data textured with the imagery as a 3D model that Google Earth can view. The problem of course is that I need to keep my files small (~1MB) so Google Earth can open them. And my DEM data is just as detailed as my imagery.

 

 

I figure the solution must be similar to what the "Generate Super Overlays" does now.

 

 

So the question is: How can I generate tiled 3D models and KMLs at various resolutions that will mimic the behavior and file setup of the "Generate Super Overlays"? What transformers should I be playing with to get this behavior?

 

 

Thanks for any help you can give.

 

Their is one option you can cut your dem in several parts and after than you can make kml file and load .for this task you can use arcgis and your other problem is resolution then you can use the fuse option in arc gis.

I tihinl the "Prepare the imagery" on

https://developers.google.com/kml/documentation/kml_21tutorial#check-out-the-spec

kinda explains it in full.

TIle by subdivison. You can easily do this using fme. For instance using a loop to reach the required minmum size "(in our example, 256-by-256 pixels)."

You can loop a gridbuilder or (mis)use the paralelel processing option.

(search forum for iterative tiler or gridder)

Building or acquiring models is, up to you i guess, as is controlling its size.
