JennD Posted February 4, 2015 Report Share Posted February 4, 2015 I have 2 feature class files of contour lines for an area of interest - from 2 different sources. We would like to select just one to use and I'm looking for any methods to effectively compare the files. I'm using ArcGIS as my primary application to run an analysis. Wondering if converting the lines to surfaces and comparing the surfaces is appropriate, or comparing values only along the lines itself? Should I be comparing to a DEM file to see which contour line deviates the most? Thank You. Quote Link to comment Share on other sites More sharing options...
Redoxi Posted March 30, 2015 Report Share Posted March 30, 2015 I think you should convert your contour files to DEM, and then compare the DEM. If you're georeferrencing is of good qualify, you may substract one DEM from another to study their diffence. You can also compute univariate statistics on your DEMs Quote Link to comment Share on other sites More sharing options...
