If you create your own maps digitally, what do you use as map-making software?
Personally, I am fond of Inkscape, as it gives me maximum flexibility and the vector-based approach is great for scaling and rotating things.
A couple years back I got illwinter floorplan [Link[(http://www.illwinter.com/floorplan/) on steam sales. Which for "indoor map" fits my need.
I don't play D&D, in general do not use "battle map" but still sometimes like to take time to visualise/describe a situation (and because it can be fun to do)
