Editing raster values based on point shp file

Discussion created by Friedel on Jun 2, 2014
Hey there,
we've a problem.
We have a DEM (digital elevation model) with a resolution of 2meter and we have points out of dgps from a river.
Now we want the implement the elevation from the dgps (point shp) for the whole river (not only for one point).
We only want to change the values for the river and not for the whole dem.

Best regards.
