Hi! I am a beginner here and I just want to know how do I make a weighted graph from a local map? The roads will be the edges and the intersections will be the nodes? I need to make one to use for application of Dijkstra's algorithm. Also, what product (or toolbox) is needed?
Like this picture below for example:

If you have a list of coordinates and a list of which nodes are connected by a road, use the graph or digraph (if you have one-way streets) functions included in MATLAB.
If you just have a picture, I think that's a bit more complicated and I don't do enough image processing to have an example ready for how to generate the list of coordinates and connections to use with graph or digraph.
