make_EPSG: Make a data frame of EPSG projection codes

Description

Make a data frame of the now-defunct European Petroleum Survey Group (EPSG) geodetic parameter dataset as distributed with PROJ.4 software and included in this package.

The data collated here are as distributed with PROJ.4.

Usage

make_EPSG(file)

Arguments

file

file name of the file matching EPSG codes and PROJ.4 arguments, should usually be autodetected
