I am using this DTM: http://ags.cuzk.cz/arcgis2/services/dmr4g/ImageServer/WMSServer?request=GetCapabilities&service=WMS

At ArcGIS I am able to ready pixel value of the raster but at QGIS it doesn't work. Tried this plugins to get the value

  • Point sampling tool
  • Value Tool
  • Profile tool

But the layer looks empty, like no pixel value in there (at ArcGIS there are).

Can anybody try me link to confirm same issue with layer? Maybe I do something wrong.

I believe the reason you cannot access the values from this DTM is because it is being served as a WMS, which QGIS is unable to obtain data from.

Sometimes some WMS work as WFS if this one does, the second answer here might be of help.


I think it is because you use WMS layer which can be served like a tiled image - not "real" DTM. Why not to use SRTM or EU-DEM?

EU-DEM https://www.eea.europa.eu/data-and-maps/data/copernicus-land-monitoring-service-eu-dem

This is an example of using EU-DEM data. I cropped some part using a polygon layer in SAGA-GIS and then applied custom styling in QGIS (nothing difficult). It is native offline dataset so I can perform various operations with it:
