How do I get edges and vertices from an OSM map?

I am looking for means to import edges and vertices from OSM map to finally make a good digraph. Can please someone help me? Automated driving toolbox imports the map but unable to fetch egdes and vertices from it.

Hi @Srinivasan V

You can use the "OpenStreetMap" Functions package from MATLAB File Exchange. This toolset is specifically designed for exactly what you're trying to do - it can import OSM files and extract the adjacency matrix representing the road network connectivity.

Using this package you can:

• Import and parse OSM XML files into MATLAB structures
• Extract the adjacency matrix of the directed graph representing road intersections
• Find shortest routes between nodes in the network
• Plot the transportation network with nodes and labels

% Basic usage example
map = parse_openstreetmap('your_map_file.osm');
plot_openstreetmap(map);
[adjacency_matrix, intersection_nodes] = extract_connectivity(map);

% Create digraph from the adjacency matrix
G = digraph(adjacency_matrix);

Please refer to the following File Exchange page for more information regarding "OpenStreetMap" Functions - www.mathworks.com/matlabcentral/fileexchange/35819-openstreetmap-functions.
