Introduction to digitizing Digitizing is the process of converting geographic features on a paper map into digital format. Errors of the operator may result in polygon knots, and loops, and there may be some errors associated with damaged source maps as well. You only require a surface layer to digitize from, but sometimes an image draped on the surface can make the view more realistic. you never had the paper map).
