[Qgis-user] "live" openstreetmap data in qgis

[kimaidou]

Hi,

If your data is not that big, you could use QuickOsm processing scripts to
automate this a bit ( and use a macro at project opening to launch the
processing model you have build combining QuickOsm algs and others more
generic algs to do the job.)
If QuickOsm lacks some features, you should improve this plugin instead of
creating a new one, IMHO.

Regards
Michaël
