Editing OSM data in QGIS looks quite difficult. The OSM data format is quite far away from any GIS format. And relations are totally not supported. I think it's out of scope for now
> Does quick OSM give us the same download as local dataset feature. I have never looked. Yes it does. You can either use the Overpass API to query the OSM database or you can open a local OSM file (PBF or XML) using your custom osmconf.ini. I think QGIS should provide a way to : * download an OSM dataset from overpass and save it to a local file. It was only XML format, but it seems PBF is supported since a few months only http://gis.19327.n8.nabble.com/PBF-output-prototype-available-for-testing-td5884534.html so I might be good to load the PBF file with OGR now. * load this file in QGIS, without having the "other_tags" column (or having hstore as mentioned). QuickOSM is doing a first loop to determine every field which are needed in the vector layer, it's quite time-consuming. 2017-10-12 14:52 GMT+02:00 Hugo Mercier <[email protected]>: > > > On 12/10/2017 14:27, Stefan Keller wrote: > > 2017-10-12 11:43 GMT+02:00 Hugo Mercier <[email protected]>: > >> On 12/10/2017 11:30, Stefan Keller wrote: > > ... > >> Support for hstore columns in qgis 3 for example could be reused in some > > > > Yes, I'm excited to hear that hstore type is part of QGIS 3. > > > >> And we would have to find a smart way to handle OSM relations. > > > > Agreed.
