Package Exports

@turf/transform-translate

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/transform-translate) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

@turf/transform-translate

transformTranslate

Moves any geojson Feature or Geometry of a specified distance along a Rhumb Line on the provided direction angle.

Parameters

geojson GeoJSON object to be translated
distance number length of the motion; negative values determine motion in opposite direction
direction number of the motion; angle from North in decimal degrees, positive clockwise
options Object Optional parameters (optional, default {})
- options.units string in which distance will be express; miles, kilometers, degrees, or radians (optional, default 'kilometers')
- options.zTranslation number length of the vertical motion, same unit of distance (optional, default 0)
- options.mutate boolean allows GeoJSON input to be mutated (significant performance increase if true) (optional, default false)

Examples

var poly = turf.polygon([[[0,29],[3.5,29],[2.5,32],[0,29]]]);
var translatedPoly = turf.transformTranslate(poly, 100, 35);

//addToMap
var addToMap = [poly, translatedPoly];
translatedPoly.properties = {stroke: '#F00', 'stroke-width': 4};

Returns GeoJSON the translated GeoJSON object
