[gdal-dev] Missing EPSG Codes and importFromUrl

[David Baker (Geoscience)]

Andy,

Great reference!  Thanks for the info.  But, when I execute the line:

var i = src.ImportFromUrl(@"http://georepository.com/search/by-name/?query=4418");

I get an error 6 of 6.  This gets back to my second question, can, and if so, how does one call on a URL to get the parameter info ?

Thanks,
David

You could try our website the GeoRepository.com

It will provide you with all the details of the CRS in question

http://georepository.com/search/by-name/?query=4418

Hope this helps

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
