I need the bounding box coordinates for NAD27 (EPSG/SRID 4267) to check the user's coordinate input.

http://spatialreference.org/ref/epsg/4267/ shows the area that doesn't cover North America at all. The EPSG Geodetic Parameter Registry gives the positive longitude as well.

What's the trick? What coordinates should I use or where I can find them?

Thanks,

yup

Are you using any GIS software to try and do this? – PolyGeo May 22 '13 at 21:18

The reason that there's a positive longitude value is because Alaska's Aleutian islands cross into the eastern hemisphere. If you can ignore those few islands, you could change the western longitude to -180, or if you can also omit Hawaii to something like -125. – mkennedy May 22 '13 at 22:27
    
PolyGeo, no, I'm just writing it in Visual Studio. – yup May 22 '13 at 23:41
    
mkennedy, thank you! I'll try it. Sounds reasonable. – yup May 22 '13 at 23:42
