Well, I want to calculate the area of a game map. To do this, I timed myself crossing an area of the game world that can be easily identified on the map. Now, I've got all my notes and measurements as a scale for the map, but I don't know how to transfer this into a total area for the map. Does anybody know how I can do this with a program or anything? I tried ImageJ but I honestly didn't understand how to work it.
