How to get the CRS from a shapefile?

[nk9]

I don't see how I can get the CRS out of a shapefile read with this library. Am I correct that these are the docs for this project? If so, I don't see "CRS" mentioned in there. Should I be using another library?

This library does not read CRS information, You can read it yourself by reading the .prj that has the same name as the .shp file and use another library that can parse the content for you

If there is no .prj file, then crs does no exists for the file

Thanks for the quick reply. There is indeed a .prj file in my case. Can you point me to another library which can parse the prj file? I'm hoping to get an EPSG number out.

You might be able to get something with proj / proj4 and/or proj4wkt
