    ptolemy

    A simple way to retrieve geographic projection information, in a variety of formats, from an EPSG SRID. Uses the epsg.io website.

    The following formats for projections are supported:

    • proj4
    • wkt
    • prettywkt (human-readable)
    • esriwkt
    • gml
    • mapnik
    • proj4js (returns js code - always be careful when using eval)

    Install

    $ npm install ptolemy
    

    Usage

    var ptolemy = require('ptolemy');
     
    ptolemy.get('4326', 'ogcwkt', function (err, resp) {
      console.log(resp);
    });
     
    // Result
    'GEOGCS["WGS 84",DATUM["WGS_1984",SPHEROID["WGS 84",6378137,298.257223563,AUTHORITY["EPSG","7030"]],AUTHORITY["EPSG","6326"]],PRIMEM["Greenwich",0,AUTHORITY["EPSG","8901"]],UNIT["degree",0.01745329251994328,AUTHORITY["EPSG","9122"]],AUTHORITY["EPSG","4326"]]'
