[Qgis-user] Subsection of an OSM dataset

[Mayeul Kauffmann]

Hi,
You could use osmosis to create a smaller .osm (providing a bounding
box). This is multiplatform.
For the remaining part, it depends on your application. Below a link
explaining why OSM shapefiles are not of very good quality:

http://www.qgis.org/wiki/Using_OpenStreetMap_data#Let_QGIS_access_OSM_data_for_rendering

In QGIS, you'll get much better result if you can run osm2postgresql,
which is optimized for QGIS:
http://wiki.openstreetmap.org/wiki/Osm2postgresql

The above requires Linux (for the first part of the script only).
However, if you understand that the following is bash:

if my_condition; then
   my_command
fi

and that "INSERT INTO" is a SQL command, then you can use osmosis
yourself and run the second part of osm2postgresql with any sql client.
