Hi folks, for everyone interested in OpenStreetMap’s fantastic road data… I’ve just posted a series of blogs about unsealed roads in Victoria. I’ve pitched it at cyclists rather than mappers to widen the audience, but you should still find lots of interest I hope.

It starts with the question, how far can you ride across Victoria without hitting a paved road? Then displays Victoria’s major ‘gravel zones’, and plots the route that crosses Victoria from west to east which contains the shortest possible distance of paved roads. It’s very circuitous.

A series of supplementary posts expand on the main theme and describe how the maps and routes were made. I hope you find it interesting. Best wishes Ian

We just need to select the smallest number of large gravel zones that lie between our starting point and destination. The route with the shortest length of paved roads must travel through these zones.

is not necessarily true
