All,

Working in C#...  I have need for EPSG:4418. Per http://www.epsg-registry.org/ 
this is the code for "ProjectedCRS [NAD27 / BLM 18N (ftUS)]".  This code does 
not seem to be in the GDAL/OGR/Prog4 database in FWTools2.4.7.  Executing the 
line:

var i = src.ImportFromEPSG(4418);

This call returns an error indicating the code is invalid.  I also searched the 
/data directory for this projection but was not able to find it.  So my next 
move was to try:

var i = 
src.ImportFromUrl(@"http://www.epsg-registry.org/export.htm?gml=urn:ogc:def:crs:EPSG::4410";);

This did not work either.

So my general question is, for missing CRS's how does one retrieve the 
projection information from the web?

Thanks in Advance,
David
