I am currently working on a project for which I need to get GIS maps of India at a district-level in the 80's and 90's. India's district and state boundaries have changed over the time period 1980-2011 considerably, and I need to map these changes over time.
Most of the versions that I found online are current (or based on the 2011 Census). Is it possible to find these older GIS files?
I would really appreciate your help.
Regards,
Susan
