Save TIFF from WMS layer QGIS for bhuvan lulc

Question

I am new to QGIS. I was trying to export .tiff from WMS layer.

WMS URL is :

https://bhuvan-ras2.nrsc.gov.in/cgi-bin/LULC250K.exe

This WMS layer is from bhuvan for lulc data India.

https://bhuvan-app1.nrsc.gov.in/thematic/thematic/index.php

I can successfully add layer to QGIS but fail to save it as .tiff . My settings while saving TIFF file:

Problem is it does not create any .tiff file, even though it reports it has created a tiff. Exporting the layer as another data type (GeoPackage) to the same location works.

How can I save it as .tiff and how to check what formats are supported by a WMS service ?

Answer 1

you need to set resolution to 5 or 10 meter(project unit),extent as same as the layer,uncheck the vrt option and then you are good to go.

Answer 2

You can check the output formats available by looking at the GetCapabilities response:

<GetMap>
  <Format>image/png</Format>
  <Format>image/jpeg</Format>
  <Format>image/png; mode=8bit</Format>
  <Format>application/x-pdf</Format>
  <Format>image/svg+xml</Format>
  <Format>image/tiff</Format>
  <Format>application/vnd.google-earth.kml+xml</Format>
  <Format>application/vnd.google-earth.kmz</Format>

or by right clicking the layer in the browser and selecting layer properties.

Also the image formats that are available in the service for use in QGIS are shown in the WMS/WMTS data source manager, as below.

Tiff is available and selecting tiff gives you the tiff through a request like:

https://bhuvan-ras2.nrsc.gov.in/cgi-bin/mapserv.exe?map=/ms4w/apps/mapfiles/LULC250K.map&SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&BBOX=5.604149999999999743,66.76200000000000045,37.158299999999997,98.64979999999999905&CRS=EPSG:4326&WIDTH=780&HEIGHT=771&LAYERS=LULC250K_0405&STYLES=&FORMAT=image/tiff&MAP_RESOLUTION=96&TRANSPARENT=TRUE

I'm not sure why the file isn't created when you export it though.
