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 whichdistance
will be express; miles, kilometers, degrees, or radians (optional, default'kilometers'
) -
options.zTranslation
number length of the vertical motion, same unit of distance (optional, default0
) -
options.mutate
boolean allows GeoJSON input to be mutated (significant performance increase if true) (optional, defaultfalse
)
-
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
