Package Exports

@turf/projection
@turf/projection/package.json

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@turf/projection) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

geojson (GeoJSON | Position) WGS84 GeoJSON object
options Object? Optional parameters
- 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
