I would like to obtain the information of a raster layer at some points. Apparently the Point sampling tool does the job. I have used this tool, and all the raster values extracted at specific points are NULL... Both vector and raster layer are in the same CRS. I use QGIS 2.0.i in Windows 8.1. Any clue ?
By the way, does anybody knows how the raster value is computed by this tool = Is it interpolated ? or is it the closest raster value to the point coordinate ? )
