What I'm looking for is a tool to generate for me floorplans and maps for a wide array of situations. Home and office interiors are foremost, towns, streets, cities, and more are desired.
There are already a lot of great tools on the internet to help gamers (http://donjon.bin.sh/ stands out). And I know there are a lot of great hand crafted ones for sale. But I've not been able to find a tool (or group of tools) that allows me to create the wealth of modern setting maps and other resources I want. Shadowrun is what has really inspired the search, but such tools would be useful for a great number of systems.
I'm planning to use these maps as aids for theater of the mind in-person games, with either printouts (I have access to a decent array of printers) or computer screens (on a large screen laptop).
Are there any tools that do this? Or are there any open source projects that get close? (I'm a web developer professionally and might consider pitching in if someone is chasing this dream.) I'm specifically looking for a tool to create the resources for me, not a visual tool that allows me to create them myself. Procedural generation of some sort (or maybe something that just has a mind boggling archive it draws from?).
