ridge maps or shapefiles of the Hills of India

[Prabhakar Shukla]

Dear all,

I hope this message finds you well.

I am currently working on a hydrological research project and am looking for ridge maps or shapefiles of the Hills of India to support terrain and watershed analysis.

I have already explored Bhuvan and Bhukosh portals, but unfortunately, I could not find data suitable for my research requirements.

Could anyone please guide me on where I might access such datasets or share any relevant sources (e.g., open GIS repositories, government data portals, or academic resources)?

Any leads or suggestions would be highly appreciated.

Thank you in advance for your time and help.

Best regards,

Prabhakar

Hi, 

I haven't done it but you can probably extract what you need from DEM data: https://www.data.gov.in/keywords/dem

Had to delineate ridges recently and had similar trouble finding a dataset. At the end, the best was to manually digitize them using micro watershed boundaries as a reference.

These are what the micro watersheds look like and each watershed boundary always follow the ridges https://amche.in/?layers=mapbox-satellite,india-micro-watersheds&terrain=1.5#9.58/15.4377/73.9995

Raw data for the watersheds are at https://github.com/ramSeraph/indian_water_features/releases/tag/hydro-boundaries

I didn't even know that sub watershed data can be used for this purpose :). 

Also, wanted to add that Cartosat v3 30m DEM data is also accessible here - https://github.com/ramSeraph/indian_land_features/releases/tag/cartodem-30m-v3r1
