[Talk-us] Troubleshooting rendering problems

[Leroy E Leonard]

The downtown area of Decatur, GA went from it's normal, cluttered beauty to
white in the Mapnik base layer of OpenStreetMap.

http://www.openstreetmap.org/?lat=33.77322&lon=-84.29307&zoom=15&layers=M

All the data is still there. I've been doing most of the changes in the area
in the last couple of weeks, so I'm probably responsible, but I can't figure
out what I could have done to break it.

How does somebody go about troubleshooting a rendering problem like this?

I've tried reversing out the boundary edits that I've made, waiting for the
tiles to be refreshed, then no change. I've tried to set up a rendering
environment on my Windows box, but am having trouble even loading a local
OSM extract into PostGIS. Next, I guess, I would need the style rules that
are used for the Mapnik layer, but not sure where to find them. Am I going
in the right direction?

Any help would be really appreciated.
