I'm trying to use gdalsrsinfo (1.9) to extract out WKT-formatted info
from NOAA's BSB/KAP files. It works on many - but has problems with
others - and I can't find a pattern. I'm not sure if it is a problem
with the BSB driver or with gdalsrsinfo, but I'm leaning toward
gdalsrsinfo as the problem because I'm not having problems on the files
when running the other gdal tools on them (translate/gdaladdo/etc).
Any suggestions would be appreciated.
The link below is an example of a file that is giving me problems:
http://www.charts.noaa.gov/RNCs/11532.zip
Running: gdalsrsinfo -V 11532_1.KAP
gives me:
Validate Fails - SRS is not well formed
PROJ.4 : ''
OGC WKT :
"!CRR/ThiselectronicchartwasproducedundertheauthorityofUSA-NOAA/NOS.Byusingthischartyouacknowledgethatyouhaveread"
This is an example of one that works well:
http://www.charts.noaa.gov/RNCs/50.zip
Here's the output from "gdalsrsinfo -V 50_2.KAP"
