@turf/projection

toMercator

Converts a WGS84 GeoJSON object into Mercator (EPSG:900913) projection

Parameters

• geojson (GeoJSON | Position) WGS84 GeoJSON object

• options Object? Optional parameters (optional, default {})

  • options.mutate boolean allows GeoJSON input to be mutated (significant performance increase if true) (optional, default false)

Examples

var pt = turf.point([-71,41]);
var converted = turf.toMercator(pt);

//addToMap
var addToMap = [pt, converted];

Returns GeoJSON Projected GeoJSON
