How to create DEM from contours using ArcGIS Desktop?
Open the “attribute table” of the contours and click on “start Editing” and edit the elevation as desired, try to make it as close as possible to the real elevation in each point. If doesn’t make any difference delete the points. Thanks for contributing an answer to Geographic Information Systems Stack Exchange!
How to generate elevation points from contours in ArcMap?
You can use the Contour Field Name Options tool to change the elevation field name. Start ArcMap. Load an elevation point layer and contours in the map. On the main menu, click Customize > Toolbars > Production Editing. On the main menu, click Customize > Toolbars > Production Contouring.
