SEZ Shapefiles

[Sudarshan Ramanujam]

Hi folks,

Could anyone help me get a hold of a shapefile of all SEZs (Special Economic Zones) we have (current and past)? If that doesn't exist, lat-longs of them could also work. I'm trying to put together a dataset that basically gives: SEZ name, when it was notified, when it became operational, when it went out of operation if it did and it's location (ideally a multipolygon). I've tried looking for replication data from papers online but couldn't quite find anything. 

I would be very grateful if someone could help me with the same or point me in the right direction. Thanks!

This has location - point data of all SEZs. I have the downloaded geojson file from the same source, and I can share it here in case this is helpful. Let me know, thanks.
