Customizing OSM map with osm2postgresql & QGIS
Loading...
Uploaded by mayeulk on May 18, 2011
Discover how to customize your own map with openstreetmap data with a few cliks!
The data was imported to a new postgresql/postgis database with a single line command using my osm2postgresql bash script.
This works with qgis 1.6 (you need qgis 1.7 if you want both rule-based rendering AND symbol levels). For the symbology for ways, I use map units (and I meant them to be meters: a road can be 30 meter wide, not 30 degrees!).
In the middle of the video QGIS seems slow then there is an orange screen, because I made a mistake: On this database, I have latitude-longitude data [1] ... and I forgot to check the "reproject on the fly" checkbox in QGIS, so in the video you see QGIS making some time to draw roads of 30 degrees ! (hence the orange screen).
[1] Note that osm2postgresql can reproject when importing an .osm file; this improves rendering performance. You should use it!
