geometry multi_polygon Sınıfı

Giriş
Şu satırları dahil ederiz.

#include <boost/geometry.hpp>
#include <boost/geometry/geometries/point_xy.hpp>
#include <boost/geometry/geometries/polygon.hpp>
#include <boost/geometry/geometries/multi_polygon.hpp>

Constructor

Şöyle yaparız.

using PointType = boost::geometry::model::d2::point_xy<double>;
using PolygonType = boost::geometry::model::polygon<PointType>;
using MultiPolygonType = boost::geometry::model::multi_polygon<PolygonType>;

MultiPolygonType polygon;
boost::geometry::read_wkt("MULTIPOLYGON(((...)))", polygon);

push_back metodu
Elimizde iki tane polygon olsun.

PolygonType singlePolygon1;
PolygonType singlePolygon2;

boost::geometry::read_wkt("POLYGON((...))", singlePolygon1);
boost::geometry::read_wkt("POLYGON((...))", singlePolygon2);

boost::geometry::correct(singlePolygon1);
boost::geometry::correct(singlePolygon2);

Şöyle yaparız.

MultiPolygonType polygon;
polygon.push_back (singlePolygon1);
polygon.push_back (singlePolygon2);
