Re: Fwd: [gdal-dev] kml superoverlay help request
Brian Basicly you need to build a vrt out of every image in the level of intrest, in this case they seem to be the 7th level. attatched is a script to do so.

Re: [gdal-dev] kml superoverlay help request
Brian IIRC the superoverlay driver is read only. Reading images from knls are problematic at best. Can you give me some info on the stucture of the kmz's?

RE: [gdal-dev] kml superoverlay help request
Brian, I had responded earlier but for some reason my email was rejected by list maybe because my official ID changed. In any case below is my response. What version of gdal is this? KMLSUPEROVERLAY driver creates a hierarchy of regions that can be used to efficiently serve large set of imagery. As few points near higher resolution tiles are loaded. KMLSUPEROVERLAY driver generates kmz with this command: Gdal_translate.exe -of KMLSUPEROVERLAY c:\my.tif c:\myResult.kmz -co FORMAT=PNG I have not implemented read for KMLSUPEROVERLAY. Ogrinfo should be able to read kml but not gdal. Let me know if you have more questions. v gets appended for formats supporting virtual IO.

Yes, definitely. I meant to say that using KLSUPEROVERLAY driver you cannot read kmz. Thanks for pointing that out.
