Hi all, I'm trying to convert a contour map (PDF file) to a DEM layer in ArcMap. The contour lines are at 1-meter interval and digitalizing them all manually is too time-consuming for my project due to time limitation. Can anyone offer some suggestions for me to do it in a more efficient way?  Thank you, L.
