distanceTo(point) → {number|*}
Direct (simplistic) implementation of Algorithms for geodesics, Charles F F Karney, Journal of Geodesy 2012
(see also Geodesics on an ellipsoid of revolution, Charles F F Karney, 2011 for further explanations).

toOsGrid() → {OsGridRef}
Converts latitude/longitude to Ordnance Survey grid reference easting/northing coordinate.

Returns:
OS Grid Reference easting/northing.
- Type
- OsGridRef
Example
const grid = new LatLon(52.65798, 1.71605).toOsGrid(); // TG 51409 13177
// for conversion of (historical) OSGB36 latitude/longitude point:
const grid = new LatLon(52.65798, 1.71605).toOsGrid(LatLon.datums.OSGB36);
