This video helps to demonstrates how to use Arcgis IDW interpolation technique for converting manually collected lat, long and elevation information to DEM and generate Contours.
Thanks for the video. I have some doubts about the previous one where you had demonstrated the process of converting the DEM to point values in an excel file. If I want to give a constant value (for example soil unit weight) for an entirely new layer and want to overlap it on the layer from where we derived the excel values, how do we do it?
