We do so in MySQL by expanding our existing geometry classes, namely Gis_point, Gis_line_string, Gis_polygon, Gis_multi_point, Gis_multi_line_string, and Gis_multi_polygon. Firstly we needed to add a few member functions for Gis_point and Gis_polygon, then we needed to define a few ...

同时Boost::Polygon的合并还存在一个问题,就是如果是点接壤那么两个图形不会被合并成一个,而Boost::Geometry的intersects支持这种情况。 经过测试,连接提取貌似是会把点接壤的两图当做有连接的,而merge的话会当成两个矩形(建议自己动手测试)。 不过,需要注意的是代码的注释里说到: ...

在上面的示例代码中,我们首先创建了一个多边形,然后使用Boost Geometry库中的函数获取了多边形的点的坐标,并输出了这些点的坐标。 需要注意的是,Boost Geometry库中的函数可以处理不仅仅是矩形,还可以处理任意多边形,包括凹多边形和自相交多边形。相关搜索:
