I have two layers: The first one is a digital elevation model (DEM) as GeoTiff. The second is a point vector layer (start and end of street segments).
What I want to do:Add elevation information to the point layer (as the new attribut hight) from the raster DEM.
My first plan: Convert DEM to vektor and than intersect with point layer. Problem here: Conversion to vektor takes extremely long time, as its a 30x30m resolution.
Do you have any other ideas?
