Purpose
This functionality can be used when the result of the nominal geocoding comes with geo-location inaccuracies. It allows to correct the azimuth start time and/or the slant range distance on the basis of a Ground Control Point.
The properly corrected product does not require any further manual correction either for the slant-to-geocoded or for the geocoded-to-slant related processes (e.g. GCP-based Geocoding, Interferogram Flattening, etc.)
Technical Note
As result of the processing, the header (.sml) of the "Input file" is modified by changing the original azimuth start time and/or the slant range distance with the corrected values.
PLEASE NOTE:
In case the auxiliary orbit file is not include in the orbit repository, a download query is performed to get the only the missing orbit file. The downloaded file is stored in the SARcape work directory and used during the import step. Once the data is imported, the orbit file is deleted.
Input Files
Input file
Input file name of the data to correct. This file is mandatory.
Geometry GCP file
Either a previously created Ground Control Point file (.xml) is loaded (Load GCP File) or the interface to create a new Ground Control Point file is automatically loaded (Create GCP File, refer to the "Tools>Generate Ground Control Point" for details). This file is mandatory.
General Functions
Exec
The processing step is executed.
Store Batch
The processing step is stored in the batch list. The Batch Browser button allows to load the batch processing list.
Close
The window will be closed.
Help
Specific help document section.
Specific Function(s)
Undo
The original azimuth start time and/or the slant range distance are restored. Only the "Input file" is required to run this function.
