Re: [Boost-users] grid_graph vertex properties

This should just be (something like):

typedef boost::property_map<GraphType, boost::vertex_index_t>::const_type indexMapType;

indexMapType indexMap(get(boost::vertex_index, graph));

boost::iterator_property_map<std::vector<float>::iterator, indexMapType> myMap(vertexData.begin(), indexMap);

// grid_graph_index_map is internal

Thanks, that seems to do it.

For posterity: http://programmingexamples.net/wiki/CPP/Boost/BGL/GridGraphProperties

For future reference, that is the approach to build external property maps for all types of graphs, not just grid graphs. -- Jeremiah Willcock
