Dear list,

Not sure whether this is the right place to ask this question, but I've been busy for quite some time trying to figure out the following:

 * I have a large number of NetCDF-files (one file for each day and
   each file containing 24 data bands = hours)
 * I have a shapefile with polygons

Now for each polygon in the shapefile I need to create a time series with values from NetCDF. This means that for every timestep I will have to extract the average value from the NetCDF within each polygon.

1. Is there a way I can do this from the command line or a DLL using
   OSGEO4W?
2. How fast is the routine? I will have to process e.g. 365 * 10
   netCDF-files

Thanks in advance for your response.

Kind regards,
Siebe Bosch
