1.相交 intersects(判断是否相交)   intersection（获取相交的几何形状）

getGeometryTypeId () 获取相交的几何类型  如：geos::geom::GEOS_MULTIPOINT等

getCoordinates ()获取相交几何的坐标序列

getSize()获取坐标点的个数

getAt(i) 获取每个点的坐标

geos::geom::Coordinate vertex(vertex_infos.at(i).x, vertex_infos.at(i).y, vertex_infos.at(i).z);
                        std::unique_ptr<geos::geom::Point> vertex_geom(geos::geom::GeometryFactory::getDefaultInstance()->createPoint(vertex));
                        auto buffer_geom = vertex_geom->buffer(15);
                        double min_distance = std::numeric_limits<double>::max();
                        if(buffer_geom->intersects(trajectory_multi_point.get()))
                        {
                            std::unique_ptr<geos::geom::Geometry> intersects_geom = buffer_geom->intersection(trajectory_multi_point.get());
                            if(intersects_geom->getGeometryTypeId() != geos::geom::GEOS_MULTIPOINT && intersects_geom->getGeometryTypeId() != geos::geom::GEOS_POINT)
                            {
                                continue;
                            }
                            //std::unique_ptr<geos::geom::CoordinateArraySequence> intersects_coordinates = intersects_geom->getCoordinates();
                            auto intersects_coordinates = intersects_geom->getCoordinates();
                            for(int i = 0; i < intersects_coordinates->getSize(); ++i)
                            {}
