cconv

#cconv - A Coordinate Conversion node module

In the chaotic world of GIS coordinate systems, a node module rises to bring a message of hope and understanding.

This module converts from geodesic latitude/longitude(degrees) to projected coordinates Easting/Northing (metres), and also the other way around.

##Usage

var cconv= require('cconv')

cB = cconv(sridA, sridB, cA, f);

var sridA = 4258; The srid of the coordinate system

var sridB = 3035; The srid of the projected system

###Forward

var f = true;

var cA = [50.000,-5.000]; [ latitude, longitude]

var cB = []; [ Easting, Northing ]

###Reverse

var f = true;

var cA = [3962799.45, 2999718.85 ]; [ Easting, Northing ]

var cB = []; [ latitude, longitude ]
