# booleanOverlap

Compares two geometries of the same dimension and returns true if their intersection set results in a geometry different from both but of the same dimension. It applies to Polygon/Polygon, LineString/LineString, Multipoint/Multipoint, MultiLineString/MultiLineString and MultiPolygon/MultiPolygon.
比较相同维度的两个几何图形,如果它们的交集集产生的几何图形与两个几何图形不同,但维度相同,则返回true。适用于Polygon/PolygonLineString/LineStringMultipoint/MultipointMultiLineString/MultiLineStringMultiPolygon/MultiPolygon

> npm install @turf/boolean-overlap

参数

参数 类型 描述
feature1 (Geometry|Feature <(LineString|MultiLineString|Polygon|MultiPolygon)>) input
feature2 (Geometry|Feature <(LineString|MultiLineString|Polygon|MultiPolygon)>) input

返回

boolean - true/false

示例

// 注意:polygon首尾坐标要一致
var poly1 = turf.polygon([[[0,0],[0,5],[5,5],[5,0],[0,0]]]);
var poly2 = turf.polygon([[[1,1],[1,6],[6,6],[6,1],[1,1]]]);
var poly3 = turf.polygon([[[10,10],[10,15],[15,15],[15,10],[10,10]]]);

turf.booleanOverlap(poly1, poly2)
//=true
turf.booleanOverlap(poly2, poly3)
//=false
