I ran gdalinfo (listed at the bottom) for a jpeg 2000 that I want to host via mapserver and it says that the EPSG code is 32128 but when I look at this EPSG code definition within mapserver listed below I noticed that the definition is listed in meters but gdalinfo is listed in feet and the definition +x_0=600000 but gdalinfo value is listed as PARAMETER["false_easting",1968500].
# NAD83 / Pennsylvania North <32128> +proj=lcc +lat_1=41.95 +lat_2=40.88333333333333 +lat_0=40.16666666666666 +lon_0=-77.75 +x_0=600000 +y_0=0 +ellps=GRS80 +datum=NAD83 +units=m +no_defs <> I created a new EPSG code called 321288 which I believe matches the definition that gdalinfo contains. Does this make sense? # NAD83 / Pennsylvania North feet <321288> +proj=lcc +lat_1=41.95 +lat_2=40.88333333333333 +lat_0=40.16666666666666 +lon_0=-77.75 +x_0=1968500 +y_0=0 +ellps=GRS80 +datum=NAD83 +to_meter=0.3048006096012192 +no_defs <> Driver: JP2KAK/JPEG-2000 (based on Kakadu) Files: A:\MappedDrives\DriveK\FTPCounties\Pa State Data\Pa Imagery\PA-Luzerne-2008\luzerne.jp2 Size is 210000, 200000 Coordinate System is: PROJCS["NAD83 / Pennsylvania North", 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["Lambert_Conformal_Conic_2SP"], PARAMETER["standard_parallel_1",41.95], PARAMETER["standard_parallel_2",40.88333333333333], PARAMETER["latitude_of_origin",40.16666666666666], PARAMETER["central_meridian",-77.75], PARAMETER["false_easting",1968500], PARAMETER["false_northing",0], UNIT["US survey foot",0.3048006096012192, AUTHORITY["EPSG","9003"]], AUTHORITY["EPSG","32128"]] Origin = (2360000.000000000000000,470000.000000000000000) Pixel Size = (1.000000000000000,-1.000000000000000) Corner Coordinates: Upper Left ( 2360000.000, 470000.000) ( 76d19'18.70"W, 41d26'52.00"N) Lower Left ( 2360000.000, 270000.000) ( 76d20'1.64"W, 40d53'56.14"N) Upper Right ( 2570000.000, 470000.000) ( 75d33'21.88"W, 41d26'8.62"N) Lower Right ( 2570000.000, 270000.000) ( 75d34'27.83"W, 40d53'13.12"N) Center ( 2465000.000, 370000.000) ( 75d56'47.50"W, 41d10'4.77"N) Band 1 Block=2048x128 Type=Byte, ColorInterp=Red Overviews: 105000x100000, 52500x50000, 26250x25000, 13125x12500, 6563x6250, 3282x3125, 1641x1563, 821x782 Metadata: LAYER_TYPE=athematic Band 2 Block=2048x128 Type=Byte, ColorInterp=Green Overviews: 105000x100000, 52500x50000, 26250x25000, 13125x12500, 6563x6250, 3282x3125, 1641x1563, 821x782 Metadata: LAYER_TYPE=athematic Band 3 Block=2048x128 Type=Byte, ColorInterp=Blue Overviews: 105000x100000, 52500x50000, 26250x25000, 13125x12500, 6563x6250, 3282x3125, 1641x1563, 821x782 Metadata: LAYER_TYPE=athematic -- John J.
