proj4node v0.0.6

Proj4node

Synchronous Proj4js slimmed down for Node.js

Usage

Convert a WGS884 coordinate to SWEREF99 TM.

var proj4node = require('proj4node'),
    sweref = new proj4node.Proj('+proj=utm +zone=33 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs'),
    p = proj4node.transform(proj4node.WGS84, sweref, new proj4node.Point(11.901, 57.689));

console.log(p);

Syncing with Proj4js SVN repository

$ git clone https://github.com/icetan/proj4node.git
$ cd proj4node
$ ./connect-proj4js-repo.sh

Then read instructions from output.

Attributions

Important to note, I have only removed functionality from the original Proj4js project. All the hard stuff (algorithms and parsing) is solely thanks to the authors of Proj4js.
