Generating random road network on existing data

Question

Hi everyone,

I wonder if there is a way to generate a random road network inside a given extent and make sure it is connected to the existing road data. As far as I know, there is the "Grow Streets" option under "Graph", yet it doesn't allow me to introduce my own streets, extent polygon or other layers to be excluded (i.e. lakes, buildings, parks).

Any suggestions for a solution?

Cheers,

Mel

Hi@MelanieVT,

Have you tried using grow streets together with an obstacle map? Here are some related links about this:

Hope this helps,
