Suppose that I’m working with
Single Look Complex images from Sentinel-1 (or any other SAR sensor).
Right now, I’m carrying out only the
Slant range to ground range projection on these images, and the resulting image’s geometry seems a bit different (distorted) from the optical one I’m visualizing on Google Maps.
Is it necessary to perform an
Ellipsoid correction after the
slant range to ground projection to have the image projected into the
WGS84projection, and therefore to obtain a geometry that is similar to the one shown on Google Maps?
