Hi,
I am trying to achieve effect of running image magick command (convert
-depth 8 -colors 32) on png files (tiles) generated by gdal2tiles.py
As far as I can tell by searching Gdal code, that there is no such option
in the png_driver. Is this correct?
If so, what is the easiest way to add this

While you certainly can accomplish this using GDAL, you'll need to first
figure out which hgt file to open, then translate the geographic coordinate
to the image coordinate to know what pixel value to lookup.
An alternative solution is OSSIM (http://www.ossim.org/). It has a

Hallo,
I need to extract the altitude of a GPS coordinate from a serie of

how can I preceed?

OK, if you evaluated using Mapnik, then I said nothing :-)
Have you experience of mapnik on windows?
Frank,
The source images are a sequence of tiles from openstreetmaps.
Every tiles has a fixed size (256 x 256) and the area they covers depends
from the zoom level.
It is explained very well in
