I'm trying to calculate if a canon will be able to shoot over a height in the terrain.
lets saytThe canon have to be 15'000-18'000m from the target, and the impact degrees have to be over 30 degrees.
So the position of the target will be known, and the result i'm looking for are the areas where one can make the shot from. It would be fairly easy if one knew both the position of the target and the canon, but my trouble is that the canon is mobile and i do't know any efficient methods to calculate for all the possible positions...
I thought of making a spheroid or something and see how/where it would intersect with the elevation model, but i don't have the competence for it.
Tried to visualize me problem and desired output.
1 image: dilemma if the canon is to close to reach over the mountain
2 image: idea of result, red areas are areas where the shot can not be made from, while the green areas are ok
I'm using ArcGis for Desktop 10.3, also have 10.2 available, all extensions.
