I would like to use this open data DSM data source QGIS from Geneva, Switzerland municipality. Here is the data server

I tried to link it as an ArcGisMapServer source or as WMTS. But when I open the layer properties, QGIS 3.12 (on Linux) cannot determine raster data type.

What am I doing wrong? Thank you very much in advance.

PS I have been struggling with this for a couple of days, sorry. At this point I do not even know if it is a dumb question...


I added https://ge.ch/sitgags2/rest/services/RASTER/MNA_SURFACE/MapServer/WMTS/1.0.0/WMTSCapabilities.xml as a WMTS server to my QGIS 3.12 and it loads fine.

  • Yes, I did that as well. But I cannot use this layer as a DTM. For example in Layer > Properties > Symbology i cannot set HIllshade, and in the Data pane QGIS says Data type: Could not determine raster data type. – Emanuele Gissi May 19 '20 at 14:20
  • I cannot even save it locally to a Geotiff file. – Emanuele Gissi May 19 '20 at 14:21
  • For example., I do not have the same problems with this WCS connection: Name: Landfire CONUS Topographic URL: landfire.cr.usgs.gov/arcgis/services/Landfire/US_other/… I import the DEM layer, and it works perfectly as a DEM – Emanuele Gissi May 19 '20 at 14:28
  • Any idea? (thank you in advance) – Emanuele Gissi May 20 '20 at 8:18
  • that is because WMTS layers are pictures of your data not the data itself – Ian Turton May 20 '20 at 8:20
