Hello everyone,
I am trying to get height change in the water level (rivers, lakes) from sar images,
How you guys suggest processing chain and method?
Is it possible directly through the interferometry to get differences?
If there are some related existing topics already, please navigate me?
Cheers,
Mapping water bodies with SAR data is comparably easy, beacuse they are mostly black. You could investigate the change of the coastline which should mostly correspond to the water surface level.
I am trying to estimate water level of inland water bodies using Sentinel 3 Altimeter L2 data. I am processing the file in latest version of BRAT GUI 4.2.0 x 64. To estimate the water level I am using following equation:
While executing this expression in BRAT 4.2.0, I am getting error in reading mod_dry_tropo_cor_zero_altitude_01, rad_wet_tropo_cor_01_ku, solid_earth_tide_01 and pole_tide_01 correction data.
If anybody could successfully processed Sentinel 3 Altimeter data in BRAT, I request you to kindly help me to rectify this problem.
Hi Vaibhav,
I’m facing the same problem as you mentioned in this post. If you’ve solved it, can I know how you do that?Really appreciate for your help.
If you have a high resolution DEM it’s actually quite easy for higher-than-average waterlevels. Extract the waterlevels and extract the DEM values at the edges, with some statistocs it’s a pretty good approximation of the water levels.
