[gdal-dev] ogr2ogr with OSM data error Too many tags in relation

[G. Allegri]

Hi Even, thanks.
A new run ended with the mentioned errors and a warning about a bad
polygon.
I thought it was a bad sqlite because QGIS couldn't load it, but ogrinfo
and ogr2ogr work well with it (I could convert to shapefiles).
