Hi all,
I am running SNAP 6.0 (S1TBX version 6.0.4) and I have a problem on the projection of geotiffs using the GPT. I am running a graph in SNAP on Sentinel-1 IW imagery and write the result als geotiff. All is fine and geotiff has the correct projection which I can see in ENVI/IDL.
If I am running the same graph in the GPT, saving the output as geotiff, the projection is wrong/missing.
I tested with a standard graph (Read --> Apply-Orbit-File --> TOPSAR-Split --> TOPSAR Deburst --> Terrain Correction).
Is this a bug in GPT of SNAP 6.0? I have not observed this problem in GPT SNAP 5.x - as far as I remember corretcly.
Thanks for your help,
Tobias
The correct geotiff tags should be:
** Structure <2bc01ec0>, 6 tags, length=176, data length=166, refs=1:
MODELTRANSFORMATIONTAG
DOUBLE Array[4, 4]
GTMODELTYPEGEOKEY
INT 1
GTRASTERTYPEGEOKEY
INT 1
GTCITATIONGEOKEY
STRING âWGS 84 / UTM zone 32Nâ
PROJECTEDCSTYPEGEOKEY
INT 32632
PCSCITATIONGEOKEY
STRING âWGS 84 / UTM zone 32Nâ
But what I observe after processing with GPT is:
** Structure <2b3b3510>, 7 tags, length=48, data length=40, refs=1:
GTMODELTYPEGEOKEY
INT 2
GTRASTERTYPEGEOKEY
INT 1
GEOGRAPHICTYPEGEOKEY
INT 6326
GEOGCITATIONGEOKEY
STRING âWorld Geodetic System 1984â
GEOGANGULARUNITSGEOKEY
INT 9102
GEOGSEMIMAJORAXISGEOKEY
