Mapping terrain

Hello all,

I am new to Arduino and new to the forum. I'm working on a project that will require the scanning of terrain and mapping it (top down over ditches and trenches and such), it will let a sprayer know when the right amount has been filled to the appropriate level and shutoff. Is this something that is possible? Any help would be appreciated.

Without a great deal more information it is impossible to say.

What role have you in mind for an Arduino?

If the scanning involves a camera then processing images is well beyond the capability of an Arduino.

...R

What will you use to scan the terrain?

What does the sprayer actually spray, and how much?
