Hi,
for a site analysis I need the the distance and elevation angle from an observer point to objects at the horizon. I tried to implement this with the skyline and skyline-diagram function based on a raster DEM. So far, so good. But then the problems begin:
- "Skyline" doesn't use the elevation (Z-coordinate) of the observer point to draw the horizon line, but the elevation value of the raster. Is there a option to draw the skyline e.g. from a point two meters above the surface?
- "Skyline" actually includes a option to integrate earth's curvature, but it isn't possible to activate this option in the mentioned case. How it can be activated?
I would be glad if anyone have same ideas, because I spent a lot of time in esri-help and others without success...
Thanks,
