Whats the best method for gridding a data set consisting of digitized contours?
A. No one method is the “best”, but you can improve the results of gridding a digitized contour data set by making sure that there is a good supply of data points throughout the map area. If there is a “C”-shaped contour without other contours inside the “C”, then the entire C will be gridded as a flat area. The same thing will happen with a closed contour. You can use the Map | Digitize menu to digitize additional points within the “C”-shaped contours and closed contours and add them to your data file.
