Geo Calc

Bounding box (min/max latitude and longitude) enclosing a radius in meters around a point, with pole and 180 degree handling.

The eight adjacent geohash cells (N, NE, E, SE, S, SW, W, NW) for a geohash, wrapping at 180 degrees longitude.

Convert WGS84 latitude/longitude to UTM (zone, band, easting, northing) and MGRS, with Norway/Svalbard zone rules.

Convert a coordinate pair between decimal degrees, degrees-minutes-seconds and degrees-decimal-minutes.

Destination latitude/longitude and final bearing from a start point, initial bearing and distance (WGS84, Vincenty).

Ellipsoidal (WGS84, Vincenty) distance and bearings between two points, compared with haversine on a sphere.

Decode a geohash to its center latitude/longitude, bounding box and the plus-or-minus error in degrees.

Encode latitude/longitude as a geohash (1 to 12 characters) with the cell bounds, center and size in meters.

Decode a Plus Code (Open Location Code) to its area and center; recovers short codes near a reference point.

Encode latitude/longitude as an Open Location Code (Plus Code) with its area bounds and a short local form.

Area, perimeter and centroid of a lat,lon polygon using spherical excess on the WGS84 equal-area sphere.

Convert a UTM (18T 585628 4511322) or MGRS (18TWL8562811322) reference to WGS84 latitude/longitude.
