Building a mega-city from Open Street Map data
"A wretched hive of scum and villainy - you'll be right at home."
Some of you will have seen the modified Tataouine map I did a few months ago. Now, we're looking to scale the process. The Tataouine map was quite fun to name all the streets for - feel free to spot the double entendre, puns and popular culture references. However, there were some lessons learned:
I'm starting on Moseli - an arm of the larger megacity of Vetawa that contains the old starport and startown, frequented by traders, free booters, smugglers and general riffraff - and of course our intrepid party of up-and-coming gangsters.
This series of postings will walk through the process of shaking down existing freely available map data into a form that lends itself to use in a role playing game. The end result will be at about the level of detail of the Duskvol map in Blades in the Dark but it will retain the skeleton of the roads, allowing more detailed sections to be overlaid in layers on the map. The map will also be tiled into chunks that can be printed out or included in a rule book.

P.S. Apologies for the teaser. The phone running the hot spot ran out of power. Onwards -

- For most of the city, it's at a level of detail that won't get used. Only certain areas need mapping in that depth.
- I didn't do a layer set with a low-res map that could be annotated with high-level detail.
- The streets are all one object. This is a bit unwieldy to work with and scales poorly.
- I didn't retain the original lines marking the actual routes of the streets. Not keeping those makes fixing the above issues much harder.
