I almost exclusively hand draw my maps- most of them on paper for campaigns that I'm running, because I generate them on the spot.

Why? Because I don't know if the players are planning to go right or left, travel to this continent or that one, and I don't have the time or motivation to map everything for my campaigns (though I plan out a general idea in my head of what's where).

When I'm doing a serious work, like an overworld map for promotional or concept art material, or a map for hire, I use a tablet and do it digitally. However, I'm trying to move towards a process of reducing my hand drawn details to certain things (like a hand full of trees) that I can clone repeatedly.

So, yes, I suppose they're still hand drawn by me, but I'm moving towards methods of producing work faster so I can get more done, so the elements that are independently hand-drawn are being reduced over time.

My maps, though, are almost exclusively of an archaic "isometric" style iconography placed on an overhead map.

I also, occasionally, hand-sculpt my maps from clay. Sand is also useful if you have access to a beach.
