Line of Sight
In earth science, "topographic profile" or "cross section" is the correct terminology. The best locations for topographic profiles will be perpendicular to features like ridges, valleys, sand dunes.
Graphically displays the line of sight between two points (whether or not the points share intervisibility), in black with intervening terrain shown in red if masked or green if visible, and can be used to determine LOS for:
Line of sight/Topographic Profiles directions.
Create terrain profile from line shape file.
Stream Profile plot longitudinal profile of a stream valley by clicking on points on map.
