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!
