Where can I find EPSG codes?

[Aaron Racicot]

John,
Just realized that the EPSG entry that I sent you was in meters, yet the
name of the projection you are trying to locate has "Feet" in the
name... Looks like you might be after a non-standard projection that is
not defined in the EPSG file?  I am not familiar with Alabama's state
plane coordinate system but it looks like they are in meters, so you
might have to do some local digging or define your own projection and
forgo the convenience of the EPSG codes.

Good luck...

Aaron

John,
The EPSG codes can be found using your local installation of PROJ.4.  On
my machine this is located at:

/usr/local/share/proj/epsg

I also took a quick look and found this in the EPSG file... Hope it
helps.

# NAD83 / Alabama West
<26930> +proj=tmerc +lat_0=30 +lon_0=-87.5 +k=0.999933 +x_0=600000
+y_0=0 +ellps=GRS80 +datum=NAD83 +units=m +no_defs  <>

I'm looking for NAD_1983_StatePlane_Alabama_West_FIPS_0102_Feet.  I've
done a google search on EPSG and lookup (among others) and haven't found
it (though it might be in there somewhere :-)


Where do you look up this stuff?

Thanks,

John Cole
