我有两个多边形,它们交叉但无法去除。我试图通过从第一个多边形中减去第二个多边形的区域来找到它们之间的差异,并再次找到它们的交集 - 结果交集仍然存在并且有公共区域。为什么会发生这种情况?如何消除两个多边形之间的交集,并使它们的边界相接?

const difference = turf.difference(turf.polygon(poly1), turf.polygon(poly2)); // removed poly2 from poly1, difference now is Feature<Polygon>
const intersection = turf.intersect(turf.polygon(difference.geometry.coordinates), turf.polygon(poly2));
if (intersection) { //intersection is geometry collection with polygons
// why???
}
