Extracting data from a raster file with the borders of polygon (vector in shapefile)

Hi everyone,

I am working with geotiff files and I want to extract the value of part of it restricted by a polygon in a shapefile. In ARC GIS there is a command called "extract by mask" and it is possible to extract part of a raster file using a polygon or another smaller raster which is smaller than the original file. Let me know how I can do it.

Cheers Abbas

This may not be exactly what you're looking for, but you could interpolate values given by lat/lon or map x/y using geotiffinterp. You may be able to adapt the regridding example in that link to suit your needs.

You can use clip raster by polygon function.
