#2223 assigned defect

CEOS driver doesn't recognize beam mode in RADARSAT-1 ScanSAR imagery

Reported by: allanx13 Owned by: pvachon
Priority: normal Milestone:
Component: GDAL_Raster Version: unspecified
Severity: normal Keywords: CEOS
Cc: pvachon, antonio

Description

The beam mode for RADARSAT-1 ScanSAR products is found in the trailer file. Currently, the CEOS driver (ceos2/sar_ceosdataset.cpp) does not look in the trailer for this value. So, the CEOS_BEAM_TYPE metadata field is not added to the product's metadata.

Allan,

Can you point me to a dataset demonstrating this issue?

Frank,

I just sent you an e-mail pointing to a ScanSAR product for download.

Apart from the beam mode, there are a few other metadata items not being reported by GDAL for the ScanSAR product:

CEOS_DM_SLOW_ALPHA CEOS_DM_FAST_BETA CEOS_DM_FAST_ALPHA_2 CEOS_DM_FAST_ALPHA CEOS_DM_TRANSPOSE CEOS_DM_SLOW_BETA CEOS_DM_START_SAMPLE CEOS_DM_START_PULSE CEOS_DM_CORNER

It'd be nice to have these values reported, although the beam mode is definitely the most important of the bunch.

Hi Allan,

Mind pointing me to the dataset as well, perhaps I can look into this at some point today.

Cheers, Phil
