ecef-projector
convert geodetic coordinates (lat,lon, alt) to ecef (cartesian x,y,z) and ecef (cartesian x,y,z) to geodetic coordinates (lat,lon, alt)
example
var projector = require('ecef-projector');
var xyz = projector.project(37.8043722, -122.2708026, 0.0);
console.log(xyz);
var gps = projector.unproject(xyz[0], xyz[1], xyz[2]);
console.log(gps);
output:
$ node ecef.js
[ -2694044.4111565403, -4266368.805493665, 3888310.602276871 ]
[ 37.8043722, -122.27080260000001, 0.0 ]
methods
var projector = require('ecef-projector')
var xyz = projector.project(lat, lon, elevation)
Return an array xyz
of [x,y,z]
coordinates in meters from lat
