在给定的方向角上沿沿恒向线移动指定距离的任何geojsonFeature或几何图形。

参数

参数	类型	描述
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	可选参数：见下文

options选项

属性	类型	默认值	描述
units	string	kilometers	in which
zTranslation	number	0	length of the vertical motion, same unit of distance

示例

// 注意：polygon首尾坐标要一致
var poly = turf.polygon([[[0,29],[3.5,29],[2.5,32],[0,29]]]);
var translatedPoly = turf.transformTranslate(poly, 100, 35);
