[Boost-users] boost::geometry::model::linestring

Hi all, I have the following code. I can correctly print the content of line_smp with boost::geometry::dsv but get strange results when I copy line_smp into a vector and then print the content of the vector. Any ideas on what I am doing wrong? bg::model::d2::point_xy p; while(rs->next()){ bg::set<0>(p, i); bg::set<1>(p, rs->getDouble("num")); i++; line +=p; } boost::geometry::simplify(line, line_smp, 0.3); std::cout<< " original: " << boost::geometry::dsv(line) << std::endl << "simplified: " <(v[i]); cout << sa; sa.str(""); }
