I don't have keep a tally of map types, but we do have 50 maps now. Most of those are overland, but we have a couple of cities, a handfull of buildings and at least one outside battlemap. You can check the list of maps, the names often betray their type.
Heads-up for Monsen: I'm getting a Runtime Error message when trying to access the Drunken Sailor Inn's Cellar map in the Atlas this evening. This applies whether I click on the highlighted stairway of the Ground Floor map, or using the link from the Latest Map Updates page, so I'm guessing there's been some glitch in the address line, or some aspect of the linking software. Everything else seems to be fine among the newer files.

overland: 39; Inns: 2; City: 1; ruins: 3; religious: 2
Which is 47, but if I count each one in the list, I get 51. So, I'm not sure where I made my mistake.
