Yes,

the grey polygon shows the area (convex hull over the points reachable within 5 minutes on the street network) reachable within 5 minutes from the read dot.

Richard, can you explain what does this definition do?

It calculates all the area of the pedestrian, which can be achieved in 5 minute walk?

I used Elk to collect the roadmap data (so it's based on the information avalible fromopen street map) and than spiderweb to callculate the distances.

Asuming that a persons walks with 4 km/h the gray polygon marks the area reachable within 5 minutes.

The thicker blue lines is what is reachable with a maximum angular change of PI > 180°

Will add this to the next SpiderWeb release as a sample... (at the moment the definition is a mass, so I can send it to you but will not post it because I doubt that anyone can read it)

Can you explain the calculation process?
