I've decided to draw maps, on these maps, I planned on drawing regions which already have determined areas (ex. Region 1 has 30.000 km²), the problem is, how would a measure a region's area on a map? Some territories have some pretty wild shapes, with many islands, which makes it very difficult to measure its area by common means. So I resorted to (bear with me) pixel counting, needless to say, that didn't work out too well, especially on bigger maps.
So I came here to ask if there's any program, app, or technique at this point, to draw lands whose size's have already been established?
Edit - I plan on drawing multiple territories, each with set areas, on the same map, so I can't draw one region and calculate it's area (on the map) then change the scale of the map so it would fit that one region's (actual) area, because it wouldn't fit the other ones.
EDIT (from JBH): The "duplicate question" does not address the question of cartography software at all. This isn't a duplicate question, but it's closed, so it can no longer be answered. However, it's worth providing a simple link to help out people interested in software for drawing maps. Visit the Cartographer's Guild list of mapping software, where you will find a great many pieces of software both paid and free. Cheers.
