Good day everyone!
I applied Mask out areas without elevation back in the Back-Geocoding operator while doing Coregistration. But water bodies (specially sea area) is not masked out in the images. DEM used was SRTM 1sec (hgt). I saw posts in this forum saying SRTM 1sec is more useful, but how was it different with the one with ‘hgt’ on it?
My study area is located in Surigao City, Mindanao, Philippines with latitude 9deg27min which is good for SRTM coverage.
