Plugin adding OSM support to QGIS
|This plugin no longer works with current OSM data, or with current versions of QGIS. QGIS 2.0 integrates OSM as a core functionality, which makes the plugin obsolete. The QGIS page has more details.|
The QGIS OpenStreetMap Plugin is a plugin for the desktop GIS application QGIS. It adds support for OpenStreetMap raw vector data, bringing it in as a layer either from .osm XML file or by direct download from the OpenStreetMap API. It also permits editing and upload back the OSM server. The plugin is at its (TODO: still in the last versions?) early stages of development. As of QGIS it has been superceded by functionality in the QGIS core.
64 bit bug and other development problems
There's a fairly serious bug at the moment. See 'openstreetmap plugin missbehaviour' and 'My lines and polygons have turned to nodes when exported as OSM XML data and imported into QGIS!'. This has appeared recently due to needing 64-bit Identifiers.
...but raises other wider discussion about 'The future of the OpenStreetMap plugin'.
If you are working with any recently added OSM data, you'll need to take a different approach. There are many other approaches, all a bit technical. You can convert OSM data to Shapefiles (or just download pre-generated shapfiles) or convert to various other formats for import into QGIS, or write OSM data into to PostGIS database. There is also a somewhat dirty hack by loading your OSM data first into JOSM, copy and paste the data to a new data layer and then save that layer (whatever you do don't upload it to OSM!). This new OSM file will not have the original ID numbers for each item so it will happily load into qgis.
It is a "core" plugin which comes with QGIS when it's first installed, and just needs to be enabled. Go to 'Plugins' menu -> 'Manage Plugins...' and find OpenStreetMap. Tick the plugin to enable it.
Having installed it you should see a new menu under 'Web' called 'OpenStreetMap'. The same new options are also on the toolbar (OSM icon).
In general consult the full manual on the QGIS site.
There is also a short description provided on the Mapperz blog.
- The 'Download OSM Data' option prompts for bounding coordinates. These default to the current viewport display in QGIS. Load any other layer to get your bearings e.g. an OSM raster layer and then you do a download when you've got a good area on screen (similar to JOSM)
- The coordinates must be in the right SRS for the OSM server (EPSG:900913) See QGIS#Setting the CRS
Data from other vector layers can be imported into the OSM layers, but attribute information does not appear to also be imported.
OSM data do not appear to be readily copied into other vector layers in a similar manner, but entire layers can be exported as shapefiles, with tags concatenated as a single attribute. Also the plugin does not handle multipolygons well - in most cases not at all! Instead you are left with lines instead of polygons
