repositioned
============
Convert positions from one coordinate system to another. Currently supports the conversion of a __customOffset__ coordinate system to __WGS84__.
Hello repositioned!
-------------------
```javascript
const repositioned = require('repositioned');
// The coordinate system has its origin at 73.57123°W, 45.50883°N
// and uses feet as a unit of measurement
const COORDINATE_SYSTEM = {
type: "customOrigin",
originOffset: [ -73.57123, 45.50883, 0 ],
measurementUnits: [ 'ft', 'ft', 'ft' ]
};
// This is the position in the customOrigin coordinate system
let position = [ -2240.450648739, 4071.88290589, 32.8084 ];
// This is the position converted to WGS84
let convertedPosition = repositioned.toWGS84(position, COORDINATE_SYSTEM);
console.log(convertedPosition);
```
Which should yield `[ -73.58, 45.52, 10 ]`.
Coordinate Systems
------------------
### customOrigin
A __customOrigin__ coordinate system uses an origin _other than_ 0° longitude, 0° latitude and measurements in standard units of a given type in each axis.
{
originOffset: [ -73.57123, 45.50883, 50 ],
measurementUnits: [ 'deg', 'deg', 'm' ],
horizontalPlaneRotation: 0
}
At present, the `originOffset` coordinate system is assumed to be WGS84. In future, an additional property may be added to specify this coordinate system.
