I just discovered this tool, it is really great!
I’m wondering if there are some minimal distances to get an accurate map. I have been doing isochrone calculation in a zone with a canal and no bridge within 3 min walk and yet the accessible zone is going over the water. (see picture below).
I was trying to make a point that this zone is kind of an enclave for pedestrians due to the canal but the map doesn’t go in this direction.
Thanks for your tips
