<p>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...</p>

<p>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... <a href="http://svn.osgeo.org/fdo/trunk/Providers/GenericRdbms/com/ExtendedCoordSys.txt/" rel="nofollow"><font color="#2c5893">http://svn.osgeo.org/fdo/trunk/Providers/GenericRdbms/com/ExtendedCoordSys.txt/</font></a> </p>
<p>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</p>
