Hi,
I have loads of historical maps which are georeferenced by using ground control
points in a few different custom coordinate reference systems. I have saved
each CRS into QGIS as custom projections. Everything works otherwise OK but
each time when I open the map I must select the CRS of the
the proxy.

Hi,
I have a DEM file http://latuviitta.kapsi.fi/data/dem10m/dem10.tif on my
server. GDAL can access it fine through /vsicurl/ as can be verified with
gdalinfo /vsicurl/http://latuviitta.kapsi.fi/data/dem10m/dem10.tif
However, I cannot add this URI as a raster layer by using a protocol like in

Hi,
Your method in QGIS is sound. Area is calculated using the wgs84 ellipsoid
EPSG 7030. If you reproject to wgs84 zone 35N (I thin
Hi,
I wonder what method QGIS is using when it computes ellipsoidal area with $area
function. I made a test with this EPSG:4326 polygon:

Hi,
I can add vector tiles into QGIS 3.14 from the WMTS service of the National
Land Survey of Finland with the following URL (api-key will change some day)
