We want to obtain the specific place of the boundaries of a shapefile. We want to be able to get the points of each polygon corresponding to a specific place in order to use these data in an algorithm. GRASS is the GIS that we are using. We have the elevation map from SRTM and the vector map containing the boundaries from <http://www.unsalb.org/>. Can we query/retrieve the points contained in a specific boundary for all the polygons in the vector map?

Sorry first time to use a GIS
