如果两个几何体的交集不为空集，则 Boolean-intersects 返回 (TRUE)。

🌐 Boolean-intersects returns (TRUE) if the intersection of the two geometries is NOT an empty set.

参数

🌐 Parameters

名称	类型	描述
feature1	Geometry | Feature<any>	GeoJSON 特性或几何
feature2	Geometry | Feature<any>	GeoJSON 特性或几何
options?	Object	可选参数 (默认 {})
options.ignoreSelfIntersections?	boolean	忽略输入特性上的自相交 (默认 true)

返回

🌐 Returns

boolean 如果几何图形相交则为真，否则为假

示例

🌐 Examples

var point1 = turf.point([2, 2]);
var point2 = turf.point([1, 2]);
var line = turf.lineString([
  [1, 1],
  [1, 3],
  [1, 4],
]);

turf.booleanIntersects(line, point1);
//=false

turf.booleanIntersects(line, point2);
//=true
