100 km as the crow flies. What does it look like from home?

100 km as the crow flies. What does it look like from home?

A young Grenoble engineer has developed “CovidRadius”, an interactive map to meet our legitimate need for escape (and allow Parisians to pass the Canal Saint-Martin). All in open source and without data storage.

The first time he surfed on a ride site, it was to frame our daily exits from containment. Because if the “kilometer” of dog walking or jogging seems simple on paper, it is a little less so in fact. Maxime Girard, 25, and his friend Loïc Bouvet wondered, from the start of the confinement, how far the famous authorized perimeter was going: ” we looked for an app.But those that did exist gave this information as the crow flies, not taking into account paths and roads. But to respond to the government instructions, it was necessary to work on isodistances “, explains Maxime Girard, freelance computer engineer.

A few sleepless nights and a weekend later “CovidRadius” was born. Put online on March 29 – and spotted in the process by blogger Korben – the site took off: “We exceeded one million visits two days ago! “ the Grenoblois is still surprised.

100 km as the crow flies, it’s already an adventure

With the deconfinement, the CovidRadius site. info has naturally adapted to the new “100 km” rule. This time again it is circumscribed “as the crow flies”, ” around his residence, or further away, but remaining within his department ” as the on the site of the national gendarmerie.

But do not sulk our pleasure. By bike, motorbike, car (boat?), 100 km as the crow flies, given the circumstances, it’s already an adventure. Not to mention the possibility of exceeding 100 km within the same department – a boon for the Girondins, the largest department in France, a little less for Parisians …

Open Source and no data storage

The three stooges, Maxime Girard, always technical, helped by Loïc Bouvet for the impulse and Rémi Serrano for communication, have therefore resized their site for after confinement on the same model as their previous version. Very few frills, almost no advertising, except to pay a minimum of development costs. And the assurance of not being traced or seeing our data stored: “I put the source code online (It is available on Github, the N.D.L.R. source code sharing platform). And a few seconds after entering your address, it will be deleted. I don’t want to store anything, even anonymously ” says Maxime Girard.

CovidRadius (2) has been in operation since Monday morning, and … sells dreams within a click. Just enter your address (or activate the geolocation, but with full knowledge of the facts) for the perimeter of our next escapes to appear. If I go beyond my area, an audible alert will sound every 5 seconds, coupled with a small vibration.

So from this corner of the 12the Parisian who did not allow me to reach the Bois de Vincennes before confinement without breaking the “1 km” rule, I can now safely drive to Orbay l’Abeille – but not push to Epernay . In the North, mine is Bonneuil-les-Eaux, but not Amiens. A desire for Cathedrals? For Chartres, it’s all good, but not for Rouen. Walks in the forest? And to go see the sea from the capital? It’s no.

And also :

-Besides this site of “buddies”, heavyweights of distance calculation have been able to adapt their sites. This is the case of ViaMichelin, who added a 100 km radius tab to their search bar. Here, too, just enter your address to see the circle of our possible walks appear. It is possible to deactivate all cookies beforehand, the site will work just as well.

-Warning ! government site “Geoportail”, which was recommended for walks of 1 km, does not allow a “bird’s-eye” calculation. However, if you want to see what 100 km give by road or path from home, you must enter an address, then open a window with a right click and choose: isochronous from this place. In a new window, on the right, choose “isodistance” and deactivate “isochronous”, then enter “100 km”, and “calculate”. It’s a bit long. But in the end you get an imperfect circle that can always be useful knowing that you lose precious kilometers.
