Thank you very much for this excellent instruction, really appreciated.

is it possible classify db images? for getting more classes

[@BS-AyeshaTariq]

hey ,
is data of SMAP is freely available?

[@swarnendusekharghosh9539]

Which date tells me about the acquisition date of the image in the Abstracted metadata can someone tell me, please?

[@chaskuhn6447]

are there any good lectures for radarsat-2

Hello, I have the same problem, when I want to perform the geometric correction, it does not run.

[@rayanerana9037]

Try the SRTM 1sec

[@stevenhiggins6174]

Good morning hope I am in right place

Hi, I have a problem with the Range Doppler Terrain Correction. When I try to correct with deafult options the image just doesnt show it is plain black, but ir does work with Ellipsoid correction. I was wondering why is that?

Hey, I had the same problem. Update your SNAP software to the latest edition, and try again. Hope it works.

[@alejandrofonseca1672]

@@sidharth1612 It doesn't work updating the SNAP as well

Hey, I had the same issue where the default instructions only resulted in a blank screen for the Terrain Correction step. I suspect it was due to the SRTM DEM not being downloaded. I used the SRTM 1Sec HGT (Auto Download) DEM instead, and this worked for me. I could see the DEM being downloaded in the bottom status bar, and the resultant images worked

[@robertmartinsorianomunarri3735]

It happened to me as well and what I did was to close the pop-up it started updating itself, not the program, but the plugins also, then I did the geometric correction and it worked

[@cesaraugustoarevalorivenso3551]

of the difficulties sent as consultations to ARSET, none were answered. Can I know why?
