[FWTools] try understand epsg and albers

[Brad Nesom]

I am trying to create a geotiff in the software (raster design) it is asking
for a code that I thought was EPSG code. however while trying to find out
what epsg = us48 I noticed that the dialog actually says geotiff code. Now I
am really in a loop. autocad map contains a coordinate system that is named
us48 albers equal area, nad 27 meter orig lat 23, orig long -96, northern
standard par 45.5, southern standerd par 29.5 ESRI difines the same system
as...

'PROJCS["USA_Contiguous_Albers_Equal_Area_Conic_USGS_version",GEOGCS["GCS_North_American_1983",DATUM["D_North_American_1983",SPHEROID["GRS_1980",6378137.0,298.257222101]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.017453292519943295]],PROJECTION["Albers"],PARAMETER["False_Easting",0.0],PARAMETER["False_Northing",0.0],PARAMETER["Central_Meridian",-96.0],PARAMETER["Standard_Parallel_1",29.5],PARAMETER["Standard_Parallel_2",45.5],PARAMETER["Latitude_Of_Origin",23.0],UNIT["Meter",1.0]]'>


and it says USGS after it. This is the same as EPSG 6703, I cannot find
anything that matches in the raster design code. I found USA US National
Atlas Equal Area but it is lambert azimuthal 45, -100 the code for it in
raster design is 2163 Apparently the autodesk version is supposed to be the
same as epsg as desribed in this document...
http://svn.osgeo.org/fdo/trunk/Providers/GenericRdbms/com/ExtendedCoordSys.txt/

The values in this document are what I am using in the raster design dialog
that I thought were epsg. Can someone straighten me out? I want an epsg code
for US48
