Coastal DEM Data

[Onkar Keskar]

Respective All,

Please Guide me to get the Coastal DEM data of Maharashtra state (India) where i can generate the whole DEM of Coastal area from Mumbai to Ratnagiti District.

Thanks in Advance

[Devdatta Tengshe]

What resolution of data do you need?

If 30 m is sufficient, then you can use the SRTM DEM, the  ASTER GDEM or even download the Carto DEM from Bhuvan's site.

If you need higher resolution, then you will have to pay to a commercial provider, or NRSC.

Regards,

Devdatta

Since you are talking about COASTAL DEM I think it will look good only when it includes Bathymetry  data also. 

The best or rather the only source (i know of ) of Bathymetry data is 

GEBCO ... 
https://www.gebco.net/data_and_products/gridded_bathymetry_data/

It includes land data also. 

For only land data currently the best source is  

JAXA
