[gdal-dev] make a geotiff from scratch

[Tamas Szekeres]

Hi,

You can probably use the gdal_grid application to create an
interpolated grayscale image based on the scattered points. Then you
could transform this image to a 3band RGB tif by using the vrt driver
and set up the proper scaling/LUT in the vrt file.
You could create an image pyramid and the corresponding kml by using a
gdal2tiles.py like application.

Best regards,

Tamas
