[mapserver-users] creating an epsg code that can be used within the epsg file for fwtools and MapServer

[John Mitchell]

Hi,

How would I create an epsg code that can be used within the epsg file for
fwtools and MapServer?

Below is the information that I would like to use to create an epsg code.
What would be format for the new epsg code?  Is the information listed below
enough to create an epsg code and if not what am I missing?


*The 2001 data was originally in a Guatemalan Transverse Mercator coordinate
system with the parameters shown below:

Projection: Transverse Mercator
False Easting: 500000.000000
False Northing: 0.000000
Central Meridian: -90.500000
Scale Factor: 0.999800
Latitude of Origin: 0.0000000
Linear Unit: Meter
Geographic Coordinate System: GCS_WGS_1984

*Below is the gdalinfo listing for one of files that I would like to
associate to this new epsg code:

*Driver: GTiff/GeoTIFF
Size is 11214, 7860
Coordinate System is `'
Origin = (317049.000000000000000,**1659460.000000000000000)
Pixel Size = (0.500000000000000,-0.**500000000000000)
Metadata:
  AREA_OR_POINT=Area
  TIFFTAG_SOFTWARE=ERDAS IMAGINE
  TIFFTAG_XRESOLUTION=1
  TIFFTAG_YRESOLUTION=1
  TIFFTAG_RESOLUTIONUNIT=1 (unitless)
Corner Coordinates:
Upper Left  (  317049.000, 1659460.000)
Lower Left  (  317049.000, 1655530.000)
Upper Right (  322656.000, 1659460.000)
Lower Right (  322656.000, 1655530.000)
Center      (  319852.500, 1657495.000)
Band 1 Block=11214x8 Type=Byte, ColorInterp=Red
Band 2 Block=11214x8 Type=Byte, ColorInterp=Green
Band 3 Block=11214x8 Type=Byte, ColorInterp=Blue*



Thanks,
