Kosta2002 Posted February 19, 2016 Report Share Posted February 19, 2016 (edited) Good evening, dear experts and GIS lovers. I hope local community can help me solve this. The problem is the following - it is necessary to build a polyline directly on DEM, not a projected line. The initial data below: start coordinates (X, Y, Z), azimuth 3D length (real, measured length) DEM of the study area Standard scheme (set point, CTRL + G, enter the azimuth and length) works only for 2D data and make only a projection on the surface, but projection of the line will always be different from the actual measured length . How can I build line by using measured (3D polyline) length? There is any tools or suggestions? Could I find tool in ArcMap, which let me use DEM like a reference surface and then use it for measurements? Thanks in advance!
