I want to report a problem detected.
I have reproduced the problem using several EEC images with corner reflectors located in well-known coordinates.
(1) When I import the PAZ product to SNAP (*xml) the image coordinates appear with an offset, it seems an error of interpretation of the geocoding information.
File - Import- SAR Sensors - PAZ
(2) Nevertheless, if you directly open the geotif product from the IMAGEDATA folder from the product package (*tif), the interpretation of the geocoding is good, the coordinates appear in the correct position.
File- Open Product
Maybe the problem is in the SNAP importer ¿? I have used the PAZ importer of ERDAS with the same images and the coordinates are ok.
Please, may you reproduce this problem in order to check the SNAP PAZ products importer?
This is an example of the coordinate displacement in EEC PAZ products that I have notice:
Terrain Corner coord. (WGS84) = 40º 04’0.96 ’’, -3º 32 ’02.92
(1) Image coord. Image directly imported to SNAP (*xml) = 40º04’08 ’’, -3º 34 ’01’ bad coordinates!!
Offset 2.8km aprox.)
(2)Image coord. Opening the geotif from IMAGEDATA (*tif) = 40º 04 ’01’’, -3º 32’ 03’’ coordinates are OK.
Thanks in advance!
