[gdal-dev] FWTools 2.3.0 does find State Plane projection information

[Charles Karney]

FWTools 2.2.8 and 2.3.0 seem not to know about some state plane
coordinate systems, while gdal under Linux and Cygwin report the correct
projection data.

For example, I have some imagery (a GeoTiff) for Florida downloaded from
the USGS site.  The cygwin version of listgeo reports:

  Geotiff_Information:
     Version: 1
     Key_Revision: 1.0

	End_Of_Keys.
     End_Of_Geotiff.

  PCS = 26960 (NAD83 / Florida North)
  Projection = 10933 (SPCS83 Florida North zone (meters))
  Projection Method: CT_LambertConfConic_2SP

     ProjFalseEastingGeoKey: 600000.000000 m
     ProjFalseNorthingGeoKey: 0.000000 m
  GCS: 4269/NAD83
  Datum: 6269/North American Datum 1983
  Ellipsoid: 7019/GRS 1980 (6378137.00,6356752.31)
  Prime Meridian: 8901/Greenwich (0.000000/  0d 0' 0.00"E)
  Projection Linear Units: 9001/metre (1.000000m)

  Corner Coordinates:
  Upper Left    (  419093.218,  185211.481)  ( 86d23'15.45"W, 30d39'26.37"N)
  Lower Left    (  419093.218,  183070.562)  ( 86d23'14.12"W, 30d38'16.86"N)
  Upper Right   (  420296.571,  185211.481)  ( 86d22'30.26"W, 30d39'27.02"N)
  Lower Right   (  420296.571,  183070.562)  ( 86d22'28.94"W, 30d38'17.50"N)
  Center        (  419694.894,  184141.021)  ( 86d22'52.19"W, 30d38'51.94"N)

The version of lisgeo in FWTools2.3.0 reports the same information up to
the PCS line.  Then it has

  PCS = 26960 (name unknown)
  Projection = 10933 ()

and the corner points are listed without the lat/long equivalents.

I see that there's a stateplane.csv in the FWTools distribution.  But it
appears not to be read?  (I can provide the GeoTiff, if necessary.)

Thanks.
