Re: [datameet] Re: Shapefiles for "complete" India

[Khaliq Parkar]

Hi Eric,

I am working in Bihar within Madhubani district.
Could you link me to the block level shapefiles? Do you know anyone who has 
worked at village\panchayat level divisions?

Thanks!

Re: [datameet] Re: 2011 subdistrict Maps

[Khaliq Parkar]

As Sharad said, the typologies of the settlement change every census - in 
fact, the definition of what constitutes a census 'town' for example is 
determined at the end of current round. e.g. 2001 census determined which 
settlement would be listed as what *and *how it would be studied in 2011.

Yup, they do. I have all of Maharashtra and all of Bihar, and I can acquire 
the rest too. I can gather it all and upload it (approx 6-8 GB) if 
something comes out of it.

As Sharad and Eric have been pointing out, do we have a source for the 2011 
subdivision\block boundaries of Indian States?
(I plead newbie ignorance if I have missed out something in the vast data 
flow since the last time I logged in!)

Bihar has one of the most detailed map sets I can see. They have uploaded
