要避免几何形状的交叉，可以使用GIS中的空间分析函数来实现。下面是一个示例代码，使用Turf.js库中的turf.booleanCrosses()函数来检查两个多边形是否相交：

var poly1 = turf.polygon([[[-122.801742, 45.48565], [-122.801742, 45.60491], [-122.584762, 45.60491], [-122.584762, 45.48565], [-122.801742, 45.48565]]]); var poly2 = turf.polygon([[[-122.520217, 45.535693], [-122.64038, 45.553967], [-122.720031, 45.526554], [-122.669906, 45.507309], [-122.723464, 45.446643], [-122.532577, 45.408574], [-122.487258, 45.477466], [-122.520217, 45.535693]]]); var crosses = turf.booleanCrosses(poly1, poly2); if (crosses) { console.log('Polygons intersect!'); } else { console.log('Polygons do not intersect.'); }

在上面的示例中，我们创建了两个多边形并使用turf.booleanCrosses()函数检查它们是否相交。如果相交，将输出'Polygons intersect！”；否则将输出'Polygons do not intersect.”
