Popular Mechanics: “Even in 2019, there are good reasons to own a paper map, whether it’s the kind you can grab at the gas station or a sturdy road atlas […] that lives in your car.” This is a listicle, so six reasons are given, some of which are absolute rubbish: paper maps aren’t “nearly flawless” in terms of accuracy (they do go out of date), and they’re not inherently more comparative (checking vs. online maps) than checking one online map against another (e.g. Google vs. Apple vs. OpenStreetMap). Valid points about reliability and being able to plot out your own routes, though. [CCA]
An Ottawa city councillor wants take a page out of Los Angeles’s playbook and create a real-time interactive map of the city’s road conditions. L.A.’s street assessment map rates road conditions as good, fair or poor. Since Ottawa’s roads are on balance between fair and poor, it might be revealing, if uncomfortable, to have all that road data easily accessible; at the moment it can only be accessed by asking city officials about the state of a given street.
An isochrone in a map shows with the same color all points from which it takes the same time to arrive to a specific location.
We chose 10 locations around the world and for each of them constructed the isochrones on top of the road network of the corresponding country. Consequently, we plot these isochrones using a dynamic color palette representing the diffusion from the location of interest to any other point of the road network.
Unexpectedly, we found that the isochrones follow beautiful fractal patterns, very similar to networks shaped in the Nature by rivers, veins, or lightnings.
This striking high-resolution map of Canada’s roads and highways, produced by EarthArtAustralia, is a work of GIS: it’s assembled from Canadian GIS road data, with roads coloured and weighted by importance (freeways are bright yellow, back roads are blue). This map is also inarguably a work of art: I could easily have one on my wall. It’s certainly being sold as such, with high-resolution digital downloads and prints available. (EarthArtAustralia has a number of downloadable and frameable maps based on road and waterway data: they’ve been coming at a furious clip lately.)
Interchange Choreography is a collection of maps of complicated highway interchanges by Chicago-based designer Nicholas Rougeux. “Applying colors to roads and using connecting roads to blend those colors adds structure and breathes new life in to areas that are often avoided for their complexity. The results resemble everything from dancers to otherworldly creatures.”
New Jersey’s interchanges look particularly complicated:
