I've used Dungeondraft for making battle maps. It's simple enough to use, so maybe Wonderdraft is where I should start looking. I appreciate the lack of DRM on Dungeondraft so I can put it on a couple computers I use without issues, guessing Wonderdraft is similar in that approach. Thanks for the suggestions with links! I'll definitely check them out.Yep. Inkarnate is good, and VERY simple to use. Wonderdraft is another that gives similar-ish results, but I think requires a download. Azgaar's Fantasy Map Generator might do the trick as well. Like Inkarnate, it's online, but it's map-style is much different, but you also can generate whole worlds with cultures, etc. that can act as a starting point for world building.
This is what I've used and will second. Excellent at generating a basis that you can then tweak as inspired, and has a whole host of downstream attributes like biomes and nation boundaries that populate based on what "makes sense" for that world and the variables you set. Definitely a learning curve, and more than is strictly necessary, but once I got familiar with it, I loved it.Azgaar's Fantasy Map Generator might do the trick as well.

I've never used "mapping software" in my life, rather I use standard graphics applications, in my case Xara Designer Pro, a vector drawing program like Illustrator.
