Comment nous avons enquêté avec les données d'Airbnb
Demain et dès à présent sur le site web du Temps, vous pourrez lire une enquête de notre journaliste Julie Conti sur Airbnb à Genève. L’article s’intéresse à cette plate-forme de location de logements fondée en 2008 par des Américains, et qui connaît un immense succès dans le monde entier. Et cette enquête contient une bonne dose de datajournalisme. Du journalisme de données Tout est parti d’une question. Dans de nombreuses grandes villes - Paris, New-York, Berlin - Airbnb est accusé de confisquer le marché locatif. Pour répondre à ces questions, nous aurions pu, en surfant sur le site, en lisant les commentaires, aller récupérer des informations et des témoignages au cas par cas. Nous avons essayé de travailler un peu différemment, en nous appuyant sur les données, pour tenter une approche plus globale. Voici donc le mode d’emploi de cette enquête. Première étape, récupérer les données, la matière première indispensable. Scraper, comment ça marche ? Un tableau de 1000 lignes

Workshop: Introduction to Mapping Taught by Francesca Giannetti, Digital Humanities Librarian, Alexander Library Wednesday, December 10, 2014 4:00 – 6:00 PM Alexander Library, Room 415 169 College Avenue, New Brunswick, NJ Have you been wanting to explore a geographic component to your research but don’t know how to get started? 30 must-see infographic galleries from newspapers After last month’s article highlighting data viz galleries we recommend everyone to follow, we return to this subject not only with more amazing sources of visual inspiration, but in many ways, with the true place where you’ll find the best infographics. And that’s because, before there was an Internet (or television, or radio, for that matter), infographics and maps were already present in several newspapers and magazines – something we are reminded of every Monday, as you saw earlier today. More importantly, journalistic infographics are bound (or should be, at least) to the same principles any journalistic piece is, namely in terms of the accuracy and relevance of the message/data presented to the readers. Combine that with the talent of experienced illustrators, graphic designers and copywriters, and what you have is decades of history told in infographic form.

Georeferencing imagery You can place a scanned aerial image or a historical map onto a Mapbox map with spatial referencing. Below, we go over the steps of how to take a non-georeferenced JPEG image and turn it into a geospatial dataset ready for rendering in Mapbox Studio and other Mapbox tools. Here, we use the free and open-source application Quantum GIS (version 2.4) and a couple plugins to georeference an image onto a map. We’ll then save the image and upload it to Mapbox.

The Map Academy › CartoDB.js What you’ll learn This introduction to CartoDB.js from the ground up will take you through the common uses of the library. You'll start out by pulling your maps from CartoDB with only a few lines of code. Later you'll customize your maps with JavaScript, interact with the data, add custom SQL queries, integrating other features, and much more. Prerequesites in the classroom, now unlimited — CartoDB Blog We think a lot about how mapping and technology work in the classroom. We’ve always felt that CartoDB could be used to support education in a diverse set of classes and be a go to tool for educators wanting to expose students to technologies that also can lead to research, jobs, and innovation. We also know that educators have to work really hard with typically small budgets for anything more than their own time. One of the things we have learned in our own work with CartoDB is that limits can make the tool hard to teach.

10 Dataviz Pinterest users that you must follow Since it became ‘mainstream’ – sometime during 2011 – Pinterest has grown into one of the favorite Internet destinations for those seeking to explore visual content, in its various forms and shapes. Infographics, of course, are all over the place there – including a good part of our late Tumblr archive. Despite this popularity – just check the results for “Data visualization” on Pinterest -, lack of time might be main reason why Alberto Cairo, Andy Kirk and others have a profile without anything posted there. So, we decided to pull together a quick list of Pinterest “power-users” that are very familiar to most of us that keep up with the data visualization field. They update their boards regularly, providing users with less time for curating the Internet with an almost endless stream of inspiration and references.

CartoDB at the MWC - The Next Generation Mapping platform will be Open Source — CartoDB Blog From March 2-5, we will be at the Mobile World Congress in Barcelona showcasing our latest developments in geospatial platforms and other mapping technologies.

Guardian launches open-source data journalism tool Collaborative data journalism platform Swarmize has launched today to offer editors and journalists better tools for the use of data, including real-time visualisation. Swarmize, now in alpha, won funding through the Knight News Challenge in June, and has been built at the Guardian over the last four months. "The Guardian and lots of other news organisations like to use Google Docs for collecting data," said Matt McAlister, the Guardian's general manager of new digital businesses. I'm hopeful that we'll start to see better data journalism because the tools are moving alongMatt McAlister, the Guardian "It's free, it's pretty easy to use, however it does have a lot of shortfalls," McAlister told "Data journalism has moved a lot in the last couple of years, and it [Google Docs] is just too limited for some of the sophisticated stuff that people want to do."
