Linking nodes using links in a graph based on information from another layer

Is it possible to work with layers in matlab? The first layer should contain the graph network with nodes and edges (which represents the road network).The second layer should contain information on the geographical terrain of the area which decides if a link can pass through the area. I need to add new edges to the graph based on the information from the second second layer. If this is possible how can I bring in the second layer?

You could represent the first layer as a graph object, adding coordinate information for each node to the Nodes table. For the second layer, the mapping toolbox provides different representations.
