[Qgis-user] QGIS 2.0 and reading OSM through GDAL
Hi, I ask this because I am on 32-bit Windows and therefore my QGIS 2.0 comes with GDAL 1.9 and I can't test myself yet. Question is: How well QGIS 2.0 supports reading OSM data with the GDAL read-only OSM driver http://www.gdal.org/ogr/drv_osm.html? The driver is fast with medium sized datasets. It takes 3 minutes to convert everything from a Finnish OSM data (150 MB as .pbf) into Spatialite database. GDAL driver creates 5 OGR layers from the OSM data and reading them as is may not make much sense with QGIS but with some query wizard users could select a subset of OSM data and convert those into normal GIS layers in QGIS. The wizard might help users by creating a list of columns which can be used for quories by parsing the "osmconf.ini" file. Then there should be an editable SQL query box for the final query. The contents of the box would be converted into GDAL/OGR SQL clause. The result would be something similar than this ogr2ogr command which selects all lines with any highway tag from an OSM file and saves them into shapefile. ogr2ogr -f "ESRI Shapefile" -dialect sqlite -sql "select * from lines where highway is not null" highways.shp berlin-latest.osm.pbf Once I have QGIS with GDAL 1.10 I can myself do this kind of things by writing GDAL .vrt files which would take care of the SQL part but I guess many other users would appreciate to have a wizard. -Jukka Rahkonen- ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
