Methods

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). Notable historical background to methods used.

toUtm(zoneOverrideopt) → {Utm}

Converts latitude/longitude to UTM coordinate. Implements Karney’s method, using Krüger series to order n⁶, giving results accurate to 5nm for distances up to 3900km from the central meridian.
Parameters:
Name Type Attributes Description
zoneOverride number <optional>
 Use specified zone rather than zone within which point lies; note overriding the UTM zone has the potential to result in negative eastings, and perverse results within Norway/Svalbard exceptions.

Throws:
Latitude outside UTM limits.

TypeError
Returns:
UTM coordinate.
Type
Utm
Example
const latlong = new LatLon(48.8582, 2.2945);
  const utmCoord = latlong.toUtm(); // 31 N 448252 5411933
