I've never used any type of GIS software before so I'm trying to find out if it is suitable for what I'm trying to do:
I've written a c++ program which estimates ground level noise from a distant source as a function partially of distance.
There are three things I'm looking to be able to do from QGIS,
- select a position in 3-D space,
- find the distance to the terrain below this point, and
- plot the resultant noise onto the terrain.
Is this sort of functionality achievable without significant work? If so do you have any suggestions for what should be looked up in the docs?
