[OpenLayers-Users] How to find shapefile's projection?

[Amos Hayes]

You can also search the incredibly useful spatialreference.org for  
something like "NAD83 17N".

Interestingly, searching for "NAD_1983_UTM_Zone_17N" doesn't turn up  
any results, despite being a string that exists in the PRJ file  
description you can download from that site for EPSG:26917.

I'm guessing the various format outputs are all auto-generated and  
it's a bit tricky to search them all when they are built on the fly.  
Too bad since it would be handy to help identify EPSG codes from .PRJ  
files.

P.S. Many thanks to cschmidt for helping to create that site. Very  
handy.
