Lieux de pouvoir à Paris, une carte qui dérange (Le Monde diplomatique, février 2019)
La mise en ligne en décembre dernier sur le site du Monde diplomatique de la carte des lieux de pouvoir à Paris, initialement parue dans Manière de voir en 2012, a suscité nombre de commentaires apeurés. Publier des données publiques, mais que seuls les initiés vivent intimement : ce travail journalistique a été qualifié d’« irresponsable » par Frédéric Haziza, de « faute professionnelle » par Mohamed Sifaoui, tandis que Caroline Fourest évoquait des « cartes qui incitent au lynchage ».

Navigation Apps Are Turning Quiet Neighborhoods Into Traffic Nightmares - The New York Times
But Leonia is not alone. From Medford, Mass. to Fremont, Calif., communities are grappling with the local gridlock caused by well-intentioned traffic apps like Waze, which was purchased by Google in 2013 for $1.15 billion.

Since Waze uses crowd sourcing to update its information, some people — frustrated at the influx of outside traffic — have taken to fabricating reports of traffic accidents in their communities to try to deter the app from sending motorists their way.

Observatoire sur la couverture et la qualité des services mobiles
Pour évaluer les performances des réseaux mobiles, l’Arcep considère deux critères, mis en avant sur son outil

la couverture, qui reflète sous format cartographique l’ampleur du réseau déployé par chaque opérateur (découlant de la quantité d’antennes existantes),
et la qualité des services mobiles, depuis la qualité sonore d’un appel à la rapidité de téléchargement d’un fichier.

Couverture des services mobiles

Sur la base des cartes de couverture des opérateurs, l'Arcep calcule les taux de couverture de la population et en superficie du territoire, pour les différentes technologies. Ces taux reflètent la possibilité, à l'extérieur des bâtiments, d'accéder à un service.

Fly6 Camera review - TitaniumGeek
With the Garmin Virb elite, and several other action cams, there is a built in GPS for adding data overly that will sync perfectly to the video. There is no wifi or GPS in the Fly6 but Garmins own VIRB EDIT software can be used to put on the after mentioned overlays! However the Fly6 does have a mild irritation for the Mac user – movie format is .AVI which isn’t handled superbly on the Mac. Plus, in order to use the Virb Edit software, the movie needs converting into Mpg. But again, there is a 3x price difference between the VIRB and the Fly6, so the Fly6, is still working out at very good value!

Urban Form Analysis with OpenStreetMap Data - Geoff Boeing
Given OpenStreetMap’s vast repository of walking paths and bike routes, we can easily model how trip distances and times, routing options, and accessibility change from one network type to another. OSMnx has built-in shortest path calculators to find the network distance between any two addresses or points. Beyond the basic network stats common in urban morphology and design, we can just as easily calculate advanced topological measures such as betweenness centralities, clustering coefficients, PageRanks, etc. Such measures have arisen recently from the study of complex networks in statistical physics, and provide insight into a network’s structure, performance, and resilience. Consider three small network subsets in different neighborhoods of Portland, Oregon:

Redditch to paris! help | Forum |
My top tip would be: decide HOW you are going to navigate ASAP, then practise using that method before you set off. Neither Portsmouth nor Paris are hard to find.

I'm an old git, so I use paper maps* carried in an Ortlieb bar bag mapcase, but I've observed that many young people enjoy squinting at electronic devices in bright sunlight, and rising to the challenge of their continuing electrical nourishment. If I was a really old git I'd copy out a routesheet by hand before I set off, but then if you deviate off it for some reason you're a bit stuffed. I also carry a small magnetic compass on my watchstrap, which is handy for maintaining navigational awareness in overcast or nocturnal conditions, especially if a one-way system has given the old sense of direction a dizzying stir.

Mmh! 60 km in the morning and 60 km in the afternoon. Lovely! Have a great trip.

Guest Post: In Praise of Globes | mathbabe
If you take the Gall-Peters map of the world and cut out the maps of Suriname and Iceland, then the relative areas will be correct; Suriname will be about 1.6 times as large as Iceland. However, both will have bad distortion in the aspect ratio in opposite direction; the north-south span Suriname will appear substantially larger than its east-west span; and the north-south span of Iceland will appear very much smaller than its east-west span. Both of these are terrible maps of their individual countries. If you are used to looking at maps of Iceland and then look at Iceland on the Gall-Peters map, it will look seriously wrong, for good reason.

On the other hand, if you take a Mercator map of the world and cut out the maps of Suriname and Iceland, then each one by itself is exactly the right shape; each is a fine map of its individual country. However, Iceland will be 3 times the area of Suriname instead of 2/3 the area.

Man rides 500 kilometres in wrong direction on way home for Chinese New Year |
The migrant worker, who told police who was unable to read road signs or maps, relied on passers-by to give him directions on his planned 1,700-kilometre trip north from Rizhao, a port on the Yellow Sea in Shandong province, to join his family for the festivities.

But instead of heading north to Qiqihar in China’s most north-easterly province, Heilongjiang, he was heading south and covered 500 kilometres before police stopped him.

Cycling with a classic paper map was compared with navigating with a moving map displayed on a smartphone, and with auditory, and visual turn-by-turn route guidance...

Navigating from a paper map required most mental effort and both young and older cyclists preferred electronic over paper map navigation. In particular a turn-by-turn dedicated guidance device was favoured.

Using Your Smartphone as a GPS -
There are various ways to carry your phone. We tend to keep ours in shorts pockets – which is a reason why the smaller phones can be more travel-friendly than the ‘phablets’, even if the latter have enticingly large screens. Gossamer Gear does a nice shoulder strap pocket, or there are mounts that attach to the handlebars. Watch out for dust and rain though, unless you use a Lifeproof case with their Life Active Bike Mount. Loksaks are cheap and work very well too, if you’re on a budget. And always apply a protective glass screen, like those from Zagg...
After considerable investigation, our favourite app for backcountry bikepacking is Gaia GPS, which works on both iOS and Android devices. It costs $20, which is more than most.

Unofficial TCR Advice, Navigation & Gadgets
The piece of equipment that will save you more time than any other during the TCR is not a lightweight frame or an aerodynamic pair of wheels; it is a GPS navigation device with your pre-planned route loaded onto it that you are familiar with using. It's possible to use more traditional / low-tech navigation methods like paper maps or cue sheets, but doing so will certainly cost significant time compared to having a screen on your handlebars showing where you are and which road you should take next.

You can ask GPS devices to find a route for you, but they normally choose a route that is far from optimal in terms of time and effort, and they often struggle when calculating particularly long routes. It's therefore better to plan your route on a computer at home and transfer the files to the device. It's often useful to pre-load multiple versions of some sections of the route and wait until you are there to choose one. See the Route Planning section for more advice on this topic.

Some people successfully use a smart phone for their navigation, which can work if you have a good charging setup (see the USB Chargers page) and maps pre-loaded as well as the route so that you don't need data access to view the map. Personally, I prefer to use a dedicated GPS device for navigation...

All of the Garmin Edge models mentioned as being suitable can be charged while riding (see the USB Chargers page). However, if using a dynamo-powered USB charger that doesn't include a cache battery then there is a problem with the Touring and 810 models in that every time the bike slows down too much and so the input power drops, the computer prepares to go to sleep and gives a 10 second warning for you to override this, which can become very annoying. The 1000 does not suffer from this problem, and I expect that the same is true for the Explore 1000, but I haven't tried it on that model.

The Edge 1000 and Explore 1000 share the larger screen and also have far crisper resolution than the Touring or 810 models. However, the better screen comes at a slight cost in battery life, with about 8 hours being possible from one charge for the 1000 and 10 hours for the 810, plus the models with the larger screen cost more money. I find that the difference in the screen is more than worthwhile because I can easily figure out a way to change my planned route and navigate on the fly with the Edge 1000, but I find doing so to be far more difficult with the 810 due to the reduced amount of map detail that can be viewed at one time. However, if I am sticking to my pre-planned route then the screen on the 810 works fine.

GPS cycle route planning made easy - how to plan and follow a bike route |
While plotting a route on a smartphone is probably the quickest way to get a route ready, for more detailed route planning there’s no beating the advantage of using a bigger computer screen. I can spend ages looking at online maps and researching new roads and putting together different routes.

Many of the more popular mapping services offer both an app and website, and you can often save and store a route, making it easy to get onto your phone.

London bike couriers set to map the capital's pollution |
A team of 50 cycle couriers from London same-day courier service Gophr are set to be equipped with carbon monoxide monitors to map the capital's pollution.

The project goal is to create "the world's most advanced air pollution map," and has been masterminded by former Labour minister Paul Drayson's firm Drayson Technologies, which works towards connecting the world via the 'internet of things.

Drayson Technologies has equipped Gophr cycle couriers with 50 of their carbon monoxide sensors which they call CleanSpace Tags.

These tags will collect data from the trips each rider takes every day and will compile it to make a real-time map of the air pollution levels around the city.

The cyclists are expected to cover around 17,000 per month, and the data collection won't be relying on patchy and unreliable mobile phone GPS connections. Each CleanSpace Tagged ride will have its height and real-time location data monitored using long range trackers developed by Inmarsat - a satellite communications provider - to give precise context to the air pollution data collected.

Internet mapping turned a remote farm into a digital hell | Fusion
IP mapping isn’t an exact science. At its most precise, an IP address can be mapped to a house. (You can try to map your own IP address here.) At its least precise, it can be mapped only to a country. In order to deal with that imprecision, MaxMind decided to set default locations at the city, state and country level for when it knows only roughly where the IP address lives. If it knows only that an IP address is somewhere in the U.S., and can’t figure out anything more about where it is, it will point to the center of the country.

As any geography nerd knows, the precise center of the United States is in northern Kansas, near the Nebraska border. Technically, the latitudinal and longitudinal coordinates of the center spot are 39°50′N 98°35′W. In digital maps, that number is an ugly one: 39.8333333,-98.585522. So back in 2002, when MaxMind was first choosing the default point on its digital map for the center of the U.S., it decided to clean up the measurements and go with a simpler, nearby latitude and longitude: 38°N 97°W or 38.0000,-97.0000.

As a result, for the last 14 years, every time MaxMind’s database has been queried about the location of an IP address in the United States it can’t identify, it has spit out the default location of a spot two hours away from the geographic center of the country. This happens a lot: 5,000 companies rely on MaxMind’s IP mapping information, and in all, there are now over 600 million IP addresses associated with that default coordinate. If any of those IP addresses are used by a scammer, or a computer thief, or a suicidal person contacting a help line, MaxMind’s database places them at the same spot: 38.0000,-97.0000.

Why would you use OpenStreetMap if there is Google Maps? - Geoawesomeness
In 2008, the company introduced Google Map Maker, which used a similar approach and interface to the OSM in order to gather local data from people willing to contribute where map data was hard to purchase.

The main difference between these two services is that every edit you make to OSM is owned by you and the community, while every change you make to Google Maps… will be owned by Google.

The OSM community is what makes the project so special. Thousands of volunteers from all around the globe are updating the map as their world changes around them. Every update is immediately visible to all other users and is version controlled. There are no corporate map cycle releases, approvals and KPIs that are typical to large organizations.

McGraw-Hill destroys textbook to placate pro-Israel bloggers | The Electronic Intifada
The publisher McGraw-Hill Education is destroying all copies of a political science textbook after receiving complaints from hardline supporters of Israel that it features a series of “anti-Israel” maps.

The college textbook, titled Global Politics: Engaging a Complex World, was published in 2012. But it wasn’t until early this month that the maps generated criticism from a pro-Israel blogger known as Elder of Ziyon...
The maps, which appear in chronological succession on page 123, show Palestinian land loss from 1946, one year before Zionist militias initiated the displacement of more than 750,000 indigenous Palestinians from historic Palestine, to the year 2000, by which point Palestinian land had been reduced to a handful of tiny non-contiguous enclaves in the occupied West Bank and a sliver of Gaza.

Galileo: How Europe's answer to GPS will revolutionise your phone | TechRadar
Satnav receivers work out their position by timing the signals sent out by the satellites high above. An error of just a billionth of a second results in a 30cm error range.

Galileo's clocks are accurate to less than one nanosecond per 24 hours, meaning it can pinpoint your location to within a metre. GPS' margin of error can be ten times greater. So when you're lost on foot in an unfamiliar city, Galileo will be ten times less likely to lead you astray.

Galileo's satellites also soar at a higher altitude than GPS', meaning they have a wider cone of vision and thus there's more chance of you being within range of the four satellites needed for the satnav receiver to figure out its position – which is helpful if you're exploring a remote area.

Mapbox, OpenStreetMap, and the Future of the Global Digital Mapping Industry - CityLab
conversation quickly turned to dissatisfaction shared by business leaders about the piece of OSM’s license that requires users to “share back” their improvements to the data. In some places, the legal verbiage is vague on how much and what kinds of data must be contributed back, which makes some businesses nervous that OSM s legally incompatible with their own data (i.e., user data). OSM members see the license as a way of keeping information truly open—and of preventing users from simply profiting from the data without contributing anything back.

Edit Wars in OpenStreetMap -
The other reason that I believe edit wars are less common in OSM is that OSM has a higher bar required for editing. OSM does not allow anonymous edits, and unlike Wikipedia. If a particular user is causing problems, they can be easily identified.

Additionally, OSM is quite a bit smaller than Wikipedia. Even though OSM has over 1.2 million user accounts, on a daily basis only about 2000 users ever edit the map. While 2000 is certainly not a small number, it’s relatively easy to spot a troublemaker. But even then, a single user cannot start a war- someone who changes large parts of the map on their own is an isolated vandal, while actual edit wars would require at least two parties. This virtually never happens.

When another editor makes a change to something I’ve created, in every case I’ve seen, they’re enhanced the map. Either they’ve expanded on the data that I entered or they corrected a mistake I made. This is the norm in OpenStreetMap- additive and corrective edits. Edit conflicts are so infrequent that most users will never encounter them, and even to the group that’s oversees them, they’re a special case.
