The various village/taluk shapefile layers are available in the Bhuvan
GeoServer layer listing:
http://bhuvannuis.nrsc.gov.in/bhuvan/web/?wicket:bookmarkablePage=:org.geoserver.web.demo.MapPreviewPage
Search for 'vill' for village boundaries by state. Search for 'taluk'
for all taluk boundaries. Note that the page gives a timeout error if
you take more than a few seconds and you need to start over. Since WFS
export is disabled, you can use the GeoRSS option to download the shape.
The one issue is that the attributes are encoded as an html string and
needs to be parsed out. Nikhil has a great python script to do this:
https://github.com/answerquest/asi-monuments-xml2csv/blob/master/asi-monuments2.ipynb
but needs to be customized for each layer.

Hi Thejesh:
Did you ever manage to convert the data into a polygon file? I
could not follow the technical intricacies of what you were
discussing with Palash, but certainly the original json file
posted by him did not contain the polygons and could not be
imported into QGIS. Do you now have one which can be? And is it
good quality?

Hi Thejesh
Thanks for the heads up, I wasn't aware of the underlying
architecture which is used in geo systems. So wasn't able
to understand the layers data. And now I am able to
understand how they come up with polygon on the map. Other
wise I was thinking that they somehow came up random
shapes using min max x,y.
I'm looking into the new api that you have provided and
see what I can come up with. I ll update. Any advice?

@Palash Kulshrestha
Let me know if you downloaded the shapes too.
The accuracy isn't bad for a national level project

Dear everyone: I am not sure if
someone in the group has looked at
this website:
https://ncog.gov.in/garvgis/admin/gisModule.
If one zooms in on the map
sufficiently, the website gives
district>sub-district>village
polygons. I do not have the skills to
pull out them out into .shp file but I
am hoping that someone in the group
might have the time and resources to
kindly take a look at it.
Best,
