Hi all, we recently hit a problem, that QGIS server, when serving GeoJSON data via WFS, is not using correct datum transformation parameters.
1. Original data (EPSG:5514 +towgs84=572.213,85.334,461.94,-4.9732,-1.529,-5.2484,3.5378) 2. QGIS Server GeoJSON over WFS -> automatic translation to WGS84 result is, that the GeoJSON data are shifted about 40m (which is common problem, if the data are transformed without +towgs84) In QGIS Server 2.18, there was DEFAULT_DATUM_TRANSFORM environment variable [1] but this seems to be missing in current QGIS version [2] How to force QGIS Server 3.x to use datum transformation options?
