Andreas,
Look at:

Starspan is a command line tool that uses GDAL/OGR lib. This functionality
is also available in many GIS packages with the name 'zonal statistics'.

Hi all,
I have a GeoTiff file covering the whole globe at approx. 1km
resolution. And I have a shapefile containing say 20 of polygons.
For each of the 20 polygons, I want to know the mean value of the raster
data falling inside the polygon, and possibly more statistics (max, min,
medeian, std, ...).
How can I achieve this using GDAL?
Thanks for your insight,
Andreas.
