|Sample Inn Schematic|
This type of map is mostly for use during play (with or without miniatures) and often uses the 1" to 5' scale convention. To test the output of each of the maps I used Inkwell Ideas Random Inn Generator to build a simple one storey building which I would then build in each of the mapping tools trying to stay as close to the original as possible and include as many items of decor as possible.
I restricted myself to free tools available to either download or use in a web app interface and limited myself to around 1½ hours time in order to learn the interface and build the map.
A free web app tile based editor which appears to be either a hobby project or a technical exercise. Limited functionality with only 4 layers per grid square (Floor, Walls, Objects, Special. Limited default tiles reduce its usefulness, but if you are in need of a quick map it has no learning curve at all and a reasonable output. One word of warning though, make sure that you keep your plan entirely inside the editor frame otherwise you will have difficulty exporting the result as there are no save or export functions - 5/10 " Simple, perhaps too simple"

This free web application is limited to an 8x10 grid and has a very limited tile set and you can only only uses 3 layers per square. Once you've set up an account you can add your own tiles, but there is a submission and approval process so it's not instantaneous. Development seems to have stalled at the moment and I hope that the coders pick up work again soon as this is a veery noble effort and I really like the clean no nonsense interface. 4/10 "I will follow your progress closely young Jedi"
Apologies if I've missed out any other tools, or if you know of any you want me to try out, just drop me a comment below.
