[Gdal-dev] EPSG:32111

[Simone Giannecchini]

Hi all,
a quick curiosity.
I have a geotiff that claims to be in EPSG:32111 crs. The out put of
gdalinfo on it is as follows:

Driver: GTiff/GeoTIFF
Size is 8745, 5055
Coordinate System is:
PROJCS["NAD83 / New Jersey",
    GEOGCS["NAD83",
        DATUM["North_American_Datum_1983",
            SPHEROID["GRS 1980",6378137,298.2572221010002,
                AUTHORITY["EPSG","7019"]],
            AUTHORITY["EPSG","6269"]],
        PRIMEM["Greenwich",0],
        UNIT["degree",0.0174532925199433],
        AUTHORITY["EPSG","4269"]],
    PROJECTION["Transverse_Mercator"],
    PARAMETER["latitude_of_origin",38.83333333333334],
    PARAMETER["central_meridian",-74.5],
    PARAMETER["scale_factor",0.9999],
    PARAMETER["false_easting",492125],
    PARAMETER["false_northing",0],
    UNIT["US survey foot",0.3048006096012192,
        AUTHORITY["EPSG","9003"]],
    AUTHORITY["EPSG","32111"]]
Origin = (343005.000000000000000,435015.000000000000000)
Pixel Size = (1.000000000000000,-0.999999999000000)
Metadata:
  AREA_OR_POINT=Area
  TIFFTAG_XRESOLUTION=0
  TIFFTAG_YRESOLUTION=0
  TIFFTAG_RESOLUTIONUNIT=1 (unitless)
Corner Coordinates:
Upper Left  (  343005.000,  435015.000) ( 75d 1'57.07"W, 40d 1'35.41"N)
Lower Left  (  343005.000,  429960.000) ( 75d 1'56.68"W, 40d 0'45.46"N)
Upper Right (  351750.000,  435015.000) ( 75d 0'4.65"W, 40d 1'35.92"N)
Lower Right (  351750.000,  429960.000) ( 75d 0'4.28"W, 40d 0'45.96"N)
Center      (  347377.500,  432487.500) ( 75d 1'0.67"W, 40d 1'10.69"N)
Band 1 Block=8745x1 Type=Byte, ColorInterp=Red
Band 2 Block=8745x1 Type=Byte, ColorInterp=Green
Band 3 Block=8745x1 Type=Byte, ColorInterp=Blue

Anyway if I check the EPSG SQL db I have in postgresql I see that the
definition of the unit of measure is meters.

I assume there has to be one and oly one EPSG:32111, hence how it
comes that I get two different definitions each claiming to be 32111?

I am using fwtools 1.1.3.

Thx,
Simone.
