[Gdal-dev] Subdatasets

[Murphy, David]

Hello-

 

I'm trying to run GDAL_Translate against a subdataset of CADRG RPF
dataset.  The GDALInfo results of this dataset are...

 

Driver: OGDI/OGDI Bridge

Size is 2000, 2000

Coordinate System is:

GEOGCS["WGS 84",

    DATUM["unknown",

        SPHEROID["WGS84",6378137,298.257223563]],

    PRIMEM["Greenwich",0],

    UNIT["degree",0.0174532925199433]]

Origin = (124.126904,43.092269)

Pixel Size = (0.00335787,-0.00248609)

Subdatasets:

  SUBDATASET_1_NAME=gltp:/rpf/d:/rpf:"1:50K at 2@CADRG at DMAAC@0":Matrix

  SUBDATASET_1_DESC=1:50K at 2@CADRG at DMAAC@0 as Matrix

  SUBDATASET_2_NAME=gltp:/rpf/d:/rpf:"1:50K at 2@CADRG at DMAAC@0":Image

  SUBDATASET_2_DESC=1:50K at 2@CADRG at DMAAC@0 as Image

Corner Coordinates:

Upper Left  ( 124.1269036,  43.0922693) (124d 7'36.85"E, 43d 5'32.17"N)

Lower Left  ( 124.1269036,  38.1200844) (124d 7'36.85"E, 38d 7'12.30"N)

Upper Right ( 130.8426396,  43.0922693) (130d50'33.50"E, 43d 5'32.17"N)

Lower Right ( 130.8426396,  38.1200844) (130d50'33.50"E, 38d 7'12.30"N)

Center      ( 127.4847716,  40.6061769) (127d29'5.18"E, 40d36'22.24"N)

Band 1 Block=2000x1 Type=Byte, ColorInterp=Red

  Overviews: arbitrary

Band 2 Block=2000x1 Type=Byte, ColorInterp=Green

  Overviews: arbitrary

Band 3 Block=2000x1 Type=Byte, ColorInterp=Blue

  Overviews: arbitrary

Band 4 Block=2000x1 Type=Byte, ColorInterp=Alpha

  Overviews: arbitrary

 

When I try to run GDAL_Translate.. (gdal_translate -of jp2kak
gltp:/rpf/d:/rpf:"1:50K at 2@CADRG at DMAAC@0":Matrix  gdal_jp2test.jp2) I get
an error message ...

ERROR 1: Invalid URL. The rpf directory is invalid

GDALOpen failed - 1

Invalid URL. The rpf directory is invalid

 

Any suggestions on how I should specify a subdataset here?

 

Thanks,

Dave Murphy
