IRL, I'm an #archaeologist and #GIS analyst. So I spend a lot of time looking at and working with #maps.
But I've also employed GIS in #gaming. Here I've created a hex grid over a land-use map of a lakeside subdivision near my home. I then used that as a basis for creating "Lakeside Subdivision", a map you can find in the #opensource computer version of #BattleTech, #MegaMek.
