I have an SRTM elevation map. How do I get the elevation of each point in the map? I am using GRASS. Is there a GRASS script to do such?
Maybe this answer to "Calculating difference in altitude along lines using GRASS" can help you too.
There is a command that do just what you want:
v.what.rast "Uploads raster values at positions of vector points to the table"
You need a vector file with points and a table attached to it. In the table you need to create a column to receive the values from the raster. Then run v.what.rast. It will read the raster value in the position below each point and put that number in the table.
