Summary – Create shapefiles or geotiff from a wms link using Arcgis or Qgis (digitization).

Instructions provided describe how to Create shapefiles from a wms link using qgis or Arcgis, Data used for digitization is from Bhuvan Landuse WMS link at Bhuvan Store all credit goes to bhuvan and Other departments.

Three Steps:

  1. Connect the WMS link and load the layer to digitize.
  2. Digitize features using drawing tools.
  3. Export features to required format.

Procedure

Connect the WMS link and load the layer for digitization

 

Get the URL from source website
  1. Find the Appropirate Layer on the Source Website. in my case this is :- Land Use Land Cover.
  2. Look for the Respective WMS URL For the layer. in my case this is :- http://bhuvan5.nrsc.gov.in/bhuvan/wms.

Note : You can also use the WMTS URL instead of WMS URL for same results.
