I guess location is any town,village,city, or perhaps feature, that is named on the map.. Some may have an entry on the Wiki to give you a bit of back story, or the lands creator may have some info tucked away. So you can look at the maps here, or at Ins Carto and find something that catches your eye and then contact the Lands Cartographer and let them know.

And then just jump right in. For Snapgallows, which I am mapping, and which lies in Redrobes Thrubmorton Fen, I read through his wiki entries to get the flavor of the over all country and then looked around the area it lies in to get a feel for the terrain/ border areas/ environment. From that you can pickout or surmise what type of buildings (stone or log), if fields would be for grazing or plowing and so on..
