I went to the Survey of India.

I went up to Dehradun last week to do a workshop on OpenStreetMap and Mapbox at the Indian Institute of Remote Sensing.

IIRS is run by the Indian Space Research Organisation (ISRO). They are also neighbors to the Survey of India – the national mapping agency. SoI governs all mapping activities in the country, maintains the National Map Policy and enforces publishing the correct international borders.

Recently, Google Maps got into trouble for large scale mapping activities without the permission from SoI.

SoI campus in Dehradun is massive and houses the only printing shop in India at the moment. They also sell some of the treasures and I was aiming for this.

The first day, they closed the store as I walked in at 4.45PM  and refused to let me do anything except for looking at the catalog; worth the walk. They sold maps worth 850 INR that day.

I went back the next day, right after the workshop to see more of the map room and talk to the folks there.

Gentlemen there told me that they don’t print much maps anymore. Congress government cut down funds. But SoI is not concerned, he said – ‘we are over 200 years old, most of the maps are complete now, you know.’

He pointed me to this map and said the state geospatial centers have lost their power and don’t do any printing at all. ‘People aren’t buying these maps.’ – well, duh, of course.


Everything except the toposheets are stored here

I talked about how they update the maps and they didn’t have much idea, not surprising. But I found out that SoI stores all vector data in DWG. You can buy the road network in DWG for ~ INR 6000.


I bought as many as I could.

SoI is still the primary organisation that the planning commission resorts to gather data for urban planning and infrastructure – much of this is outsourced to small agencies across the country.
