CartosatDEM V1.1.R-1

Post by pd_jayakumar » Fri Jan 24, 2014 9:26 am

Dear Bhuvan,

I have downloaded the CartosatDEM V1.1.R-1 DEM of Kadwada, where in 2009 land slide has happened.
In that DEM the low elevation point pixel is -77, but in the respected toposheet 48K10/48K14 there is that much low value.

Then I though of filling the sinks to get the desired DEM, after filling also I am getting the -values in DEM.

So Confused..... please suggest some remedy...

(I am doing digital morphometry, it is important to take the proper DEM, or else drainage will go under the datum WGS_1984)

thanks

Dear Jayakumar,
There is no CartoDEM V1.1 R1 tile/data for Kadwad. It is of CartoDEM v1. Please check it once again. You may please mention the Toposheet number (OSM) of the tile showing incorrect values.

Thanks,
S Shadab

Thanks for the replay.

Please have a look on the attachment. May the OSM series number is mismatching, but data i have downloaded is correct.

Thanks.
