Creating DEM from vector contours using GRASS and R?


I want to convert vector contours to a DEM. From other posts, I wanted to use the Grass r.surf.contours tool.



Initially, I converted the vector contour layer to a rasterized contours using the rasterize (vector to raster) tool. The contours rasterized well but there was 0 values between them.


I have tried the Grass plugin but it isn't giving me good results. I suspect it is because of the 0 values.


How do I strip these out?
