Just to add my 2 cents on this. I've done this sort of thing in the
past by using gdal_rasterize to set all pixels which are outside the
polygon(s) of interest to nodata. Then I use a very simplistic Python
script to dump all of the pixel values to STDOUT and redirect to a csv
file. It would be p

Jose,
Thanks for your pointer to your web site. Looks like you have some
very interesting and useful code there. I've been trying to do
something similar, though I use raster "zone" grids rather than vector
layers; I'd be happy to share that code, but it's too messy at this
point. I'll write a blo
Hi,
There is also a tool called Starspan than uses GDAL and GEOS to do
arbitrary zonal stats.

You can use the GDAL Python bindings for this. Refer to
http://trac.osgeo.org/gdal/wiki/GdalOgrInPython
You can also use any other language you like shown at

Can anyone get me started on a script that can -
-Open a shapefile
-Open many rasters
-Calculate the mean and standard deviation of those rasters within the
shapefile region, but is able to ignore areas of zeros or NoData
-Output the mean and standard deviation to a table
Otherwise any tu
