I have two shape files containing height information of a certain area and I need to create a raster DEM with GRASS using them.
- file 1 consists of height information in contours (isolines)
- file 2 consists of height information with spot heights
What would be the best technique to generate raster DEM with these two types of data?
Do i need to generate some spot heights from contours and then integerate with existing spot heights for DEM generation or any other method?
