Topic: using the "Offset Field" when converting Tied Points to GCPS
Rather than selecting bands containing E/W and N/S displacement for the "Offset Field" option (which accounts for the regional-scale deformation), can I give COSI-Corr two text files with long/lat/displacement in column format corresponding to the displacement at each of the GCP's I have selected in the x and y domain?
If so, must these be in geodetic or utm coordinates? If geodetic, should the displacement column (i.e. z column) be in degrees or meters?
