#Qwant_Maps arrive pour concurrencer #Google_Maps

Qwant présentait en 2017, lors du salon Vivatech à Paris, son projet Qwant Maps. Aujourd’hui, l’idée se concrétise et promet une navigation et des options avancées sans collecter de données sur l’utilisateur. Ainsi, la société française compte proposer une alternative au géant Google, y compris dans la navigation. C’est en juin dernier que Qwant dévoilait les premiers prototypes de Qwant Maps.

Esri and Winning · Paul Ramsey

Despite all that, the Esri representative still went to the president of the association, complained to her about the content of my talk, and asked her to ensure that nothing I would say in my afternoon technical talk would be objectionable to himself. (…)
For some of these people, no amount of winning is enough, no position of dominance is safe, no amount of market leverage is sufficient.

OpenStreetMap Carto Tutorials
▻https://ircama.github.io/osm-carto-tutorials

#OpenStreetMap #Carto is the style used for the Standard tile layer of OpenStreetMap.

This independent site includes unofficial #tutorials to set-up a development environment of OpenStreetMap Carto and to manage this software. It will allow exploiting the style and also being able to contribute to the developments.

To implement this site I kept track of technical notes that have been useful to me and that I hope will also be of help to master OpenStreetMap Carto fast, learning all most relevant aspects from the ground up.

All pages of this site allow commenting. You can also contribute or create GitHup issues. Opening GitHup issues is the most effective way for correction requests.

On the discussion on OSMF supported #vector #tiles maps
▻http://blog.imagico.de/on-the-discussion-on-osmf-supported-vector-tiles-maps

But trying to address this problem now by crawling under the wings of Mapbox or other big corporations and making OSMs public image fully dependent on technology developed and controlled by corporate players would in my opinion be a big mistake. Open Source or not – the past experience with Mapnik and Carto has quite well demonstrated i think that OSM currently lacks the resources and expertise to develop or to organize development of a map rendering framework for the specific needs of the project independent of either the big corporate #OSM users or the broader FOSS community.

#Itinérance_cartographique andine : #Nomad_Maps

Je souhaite partager avec vous un projet particulièrement intéressant dans lequel la #cartographie_collaborative, le #voyage et le #vélo sont mis à l’honneur.
Il s’agit de Nomad Maps, un projet porté par #Alban_Vivert, un jeune géographe/géomaticien de Lyon, et #CartONG (▻http://www.cartong.org/fr). C’est une itinérance de 6 mois à vélo à travers trois pays andins (la #Colombie, l’#Equateur et le #Pérou) axée sur « l’opportunité de la cartographie et de l’#information_géographique collaborative comme outil de développement ».

Au programme, des contributions journalières sur #OpenStreetMap, l’enregistrement du trajet sur #Mapillary, des rencontres avec les communautés #OSM sud-américaines et des micro-projets cartographiques avec des associations locales en différents points du parcours. Davantage d’informations sur les objectifs du projet et sur son déroulé sont sur le site du projet : ▻http://nomadmaps.net

Alban Vivert est l’unique voyageur-cartographe de ce premier voyage, en espérant que celui-ci soit le premier d’une longue liste et qu’une communauté de voyageurs-cartographes se créera. Une cagnotte a été ouverte pour aider au financement du projet sur cette plateforme : ▻https://www.kisskissbankbank.com/fr/projects/nomad-maps

On imitated problem solving
▻http://blog.imagico.de/on-imitated-problem-solving

As many of you know for a few years now we have a new trend in remote sensing and cartography that is called Artificial Intelligence or Machine Learning.
...
Those in decision making positions at companies like Facebook and Mapbox who try to push AI or Machine Learning into cartography (see here and here) are largely aware of these limitations. If they truly believed that AIs can replace human intelligence in mapping they would not try to push such methods into OSM, they would simply build their own geo-database using these methods free of the inconvenient rules and constraints of OSM. The reason why they push this into OSM is because on their own these methods are pretty useless for cartographic purposes. As illustrated above for principal reasons they produce pretty blatant and stupid errors and even if the error rate is low that usually ruins things for most application. What would you think of a map where one percent of the buildings are in the middle of a road or river or similar? Would you trust a self driving car that uses a road database where 0.1 percent of the roads lead into a lake or wall?
...
What Facebook & Co. hope for is that by pushing AI methods into OSM they can get the OSM community to clean up the errors their trained mechanical kids inevitably produce and thereby turn the practically pretty useless AI results into something of practical value – or, to put it more bluntly, to change OSM from being a map by the people for the people into a project of crowd sourced slave work for the corporate AI overlords.
...
Computers should perform work for humans, not the other way round.
...
In other words: You should do exactly the opposite of what Facebook and Mapbox are doing in this field.

Pokemon GO migre sur OpenStreetMap - LinuxFr.org
▻https://linuxfr.org/users/blink38/journaux/pokemon-go-migre-sur-openstreetmap

Il y a quelques jours, les joueurs de PokemonGO ont vu les cartes du jeu modifiées. Il s’agit simplement d’une bascule des cartes de Google Maps vers OpenStreetMap par Niantic, l’éditeur du jeu Pokemon GO.

Plus exactement, d’après ce que j’ai compris, Pokemon GO utilise les données OSM (libres), mais pas leurs serveurs (pas libres de tous usages).

Du coup, plus de visibilité et de contributeurs pour OSM ?

On basic small scale landcover rendering
▻http://blog.imagico.de/on-basic-small-scale-landcover-rendering

Many #OSM based #maps show #landuse areas at the high zoom levels in either a plain #color or using #patterns. At smaller scales landcover depiction is also useful in particular to delineate urban and rural areas and to allow the map user to identify different landscapes in particular if there is no relief depiction in the map. At small scales it is usually not the specific shape of individual landcover areas that needs to be shown but the overall distribution of the different landcover types. And due to the variable scale of the mercator projection certain needs for landcover depiction occur at different zoom levels depending on where on earth you look.

Mapping coasts and the tidal zone

▻http://blog.imagico.de/mapping-coasts-and-the-tidal-zone

Mapping #coasts and the #tidal zone in #OpenStreetMap is not that difficult, here the basics:

– the coastline tagged with natural=coastline is placed at the top of the tidal range.
– the tidal zone is usually mapped as as natural=wetland, with wetland=tidalflat if it is bare mud or sand, other wetland types (like wetland=saltmarsh or wetland=mangrove) apply if it is vegetated.
– shallow, elevated areas permanently under water can be mapped as natural=reef.
– sand- and gravel bars in the tidal range or raising above can be mapped as natural=shoal.
– non-vegetated coastal stretches of sand, gravel or pebbles that are formed by waves can be mapped as natural=beach – preferrably with a surface tag indicating the material.
– rocky coasts can be tagged natural=bare_rock, coastal cliffs can be mapped with natural=cliff.
– for coastal dunes you can use natural=sand, individual dunes can also be mapped with natural=dune.

You can find some more details on coastal mapping in another blog post about beaches and reefs ▻http://blog.imagico.de/reefs-and-beaches-in-the-openstreetmap-standard-style

Square-Mile Street Network Visualization

The heart of Allan Jacobs’ classic book on street-level urban form and design, Great Streets, features dozens of hand-drawn figure-ground diagrams in the style of Nolli maps. Each depicts one square mile of a city’s street network. Drawing these cities at the same scale provides a revealing spatial objectivity in visually comparing their street networks and urban forms.

We can recreate these visualizations automatically with Python and the OSMnx package, which I developed as part of my dissertation. With OSMnx we can download a street network from OpenStreetMap for anywhere in the world in just one line of code. Here are the square-mile diagrams of #Portland, #San_Francisco, #Irvine, and #Rome created and plotted automatically by OSMnx.
