booleanCrosses

描述

¥Description

如果相交结果的几何体维度比两个源几何体的最大维度小一，且相交集位于两个源几何体的内部，则 Boolean-Crosses 返回 True。

¥Boolean-Crosses returns True if the intersection results in a geometry whose dimension is one less than the maximum dimension of the two source geometries and the intersection set is interior to both source geometries.

Boolean-Crosses 仅在多点/多边形、多点/线串、线串/线串、线串/多边形以及线串/多多边形比较时返回 t (TRUE)。不支持其他比较，因为它们超出了 OpenGIS 简单特性规范，并且可能会产生意外结果。

¥Boolean-Crosses returns t (TRUE) for only multipoint/polygon, multipoint/linestring, linestring/linestring, linestring/polygon, and linestring/multipolygon comparisons. Other comparisons are not supported as they are outside the OpenGIS Simple Features spec and may give unexpected results.

示例

¥Examples

var line1 = turf.lineString([
  [-2, 2],
  [4, 2],
]);
var line2 = turf.lineString([
