OSM Tilings

Posted on 08:55 by Unknown
This is two pictures of "tilings" of OpenStreetMap for use in global scenery. I downloaded a OSM new planet extract about a month ago; in the 11 months since I last grabbed it, the data size has grown 56%! The new, larger file required some changes to my extracting code. After much debugging, I was able to see this in QGIS:


The first picture is 1x1 tiles, which are derived from the second picture (10x10s). You'll see some "ragged" edges. This is because the cutting scheme leaves whole roads of interest in one piece even outside the tiling bounds. Later, more sophisticated code crops the road when the actual DSF is built.

The OSM processing tools are part of the open source scenery tools; I will get my changes checked in to source control over the next few days, although my code is only one of dozens of programs for bulk processing OSM.
