Geolocation-Grid Ellipsoid Correction operator (Menu
Radar > Geometric > Ellipsoid Correction > Geolocation-Grid) make a prior
Slant-Range to Ground Range projection (Knowing that the EllipsoidCorrectionGG isn’t based on the use of a DEM) ?
I’m asking because I came across many
srgr variables when I browsed the
Geolocation-Grid Ellipsoid Correction operator source-code on Github https://github.com/senbox-org/s1tbx/blob/master/s1tbx-op-sar-processing/src/main/java/org/esa/s1tbx/sar/gpf/geometric/GeolocationGridGeocodingOp.java
If so, is it the same srgr as the one appearing in the menu
Radar > Geometric > Slant Range to Ground Range ?
