Hello, Some thoughts after reading the various comments.
I have worked on similar data for Delhi about 10 -12 years ago. Things might have changed now. But I guess the following. NIC (National Informatics Center) started with the original base data. They have very very strict data sharing policies. The vector data in based on NIC servers. They serve it to Municipalities and strictly monitor the usage. Municipalities draw on top of the base layers. The condition is that they can not even share that Drawn data with anyone outside a designated ROOM in soft copy. If they find violations they will stop serving Vectors (in case of Delhi DJB they were serving vector base layer data to DJB) and only serve Rasterized base data. I earned some money in a project to RE-Digitise DJB's own drawn layers from Paper Prints to give to a consultant. this is much much better that Paper prints. Digitise the Area of Interest.
