Is it possible to make a DEM from contours in QGIS? I have a shp file (contours) and their heights, can I use QGIS for produce a DEM without using GRASS?
I found this creating a dem from contours but the answer is for ArcGIS.
Yes, there are several options available in QGIS:
Raster > Grid (Interpolation). GDAL's interpolation is more robust because you can use other interpolation algorithms (IDW, nearest neighbor, moving average, etc.). This tools only works for point data.
r.surf.*). You need convert your shapefile into a GRASS database to use the GRASS modules in QGIS.
GRASS has also many options
available one way or another also trough the QGIS/GRASS plugin.
Check also this paper. I'm writing a qgis module to do that. I hope that it will be available in the next few months.
