Tripline. Tuto : Créer des cartes personnalisées (polygones) avec Tableau Public – joel matriche. Alors que Google Fusion tables et CartoDB créent facilement des cartes choroplèthes à partir, respectivement, de fichiers kml ou shp, Tableau Public ne fait pas montre de la même souplesse. Mais on peut facilement y remédier. Explication et démonstration avec les 589 communes belges. En texte, images et vidéo. Une carte choroplèthe, c’est un nom compliqué pour désigner une représentation géographique que tout le monde connaît : des territoires (pays, régions, communes, départements…) sont colorés ou remplis d’un motif en fonction d’une mesure statistique (densité de la population, revenus, résultats électoraux…) Google Fusion Tables (exemple ci-dessus) et CartoDB permettent de créer facilement ces cartes colorées en injectant les fichiers ad hoc, kml pour le premier, shp notamment pour le second.

Créer une carte choroplèthe sur-mesure avec Tableau impose de trouver le bon fichier shp (oubliez, pour le coup, les kml). Nettoyer le csv Importer le csv dans Tableau En vidéo. @joelmatriche » Le blog de jo. L'objectif : produire des cartes (dans un premier temps, non dynamiques) originales, qui changent des traditionnels plans de rues ou vues satellites.

A cet effet, je me suis inspiré des très réussis plans de villes diffusés chaque semaine par M Le Mag, le supplément hebdomadaire du Monde. Il ne s'agit pas de vouloir reproduire au pixel près les cartes de M Le Mag mais de s'en inspirer avec le plus de fidélité en ne se servant, pour l'essentiel, que d'outils cartographiques gratuits. Lorsque le processus a été compris, de nombreuses variantes sont bien sûr possibles et souhaitées, la voie est libre pour des cartes sur mesure. Attention au fait que dans cette première étape, la carte est statique, elle est délivrée sous la forme d'un fichier jpeg. Voici de haut en bas la carte de Marseille extraite du dernier exemplaire de M. Le Mag (réalisée par Satoshi Hashimoto) et celle réalisée avec qgis : Le matériel nécessaire : 1. On exporte le résultat de première requête sous le format geojson. 2.

Cartographier rapidement des photos prises avec un téléphone Vous avez pris plein de photos avec votre iPhone, Samsung ou autre appareil et voulez les mettre sur une carte qui puisse être intégrée sur votre site ensuite? Il y a plusieurs options, notamment avec Picasa, mais qui permettent peu de personnalisation. Alors on va se tourner naturellement vers du script et Leaflet. Plus précisément vers un petit code vraiment bien fait, exif-to-geojson. On l’importe sur son ordi par git : $ git clone Il crée un répertoire img où il suffit de placer les images que l’on veut cartographier. Ensuite, on l’exécute avec Terminal (ou l’invite de commandes) node exif-to-geojson.js Et hop, il crée un .geojson et surtout, il encode le tout dans un fichier index.html immédiatement utilisable.

Le résultat final est ici. What Country has the Most Unsustainable Debt? (hint: not Greece) Créer une carte. Create Free Interactive Timelines – Stories Displayed on Maps | myHistro. How to build an interactive choropleth map with barely any code. Patrick Garvin, a designer and graphic artist with The Boston Globe, has built a handy web application called Mr. Map Generator to build interactive maps of the United States.

You supply the data you want to visualize and Garvin allows you to customize how the states are shaded and how many shades you want to use. You can preview your map and then copy and paste the simple Javascript into a set of files he provides.

Google maps tutorial (part 5/5): How to create Fusion Tables heat map. Tutorial goals: understand the ideas behind Google Fusion Tables heat maps; create an interactive map showing state-by-state U.S. population, as shown in the sample below. (This post is part five of a 5-part tutorial on creating Fusion Tables intensity map; the other parts are listed as related posts at end of this post) How Fusion Tables works to create heat maps It is essential that you understand the idea and the steps in creating a Fusion Tables map; otherwise, you will easily get lost when working on the demo map in this tutorial.

In its simplest form, a Fusion Tables map is a fusion, or merger, of two tables. In the U.S. population example, I have two tables: one contains state-by-state population numbers, the other one contains geographic information of each state (i.e., shape and boundary). The typical workflow is that you manage to get hold of two tables, upload them to Fusion Tables, merge the two tables, visualized the new table on a map, style the map, then share it. Step 1.

Using IFTTT and Google Drive to create a JSON API by Nick Moreton on CodePen. JSON APIs are a pretty powerful way of connecting your frontend app to a dataset through Javascript. Most of the big web apps provide their API in JSON format (Facebook, Twitter, Instagram) however, as you may know if you've ever tried to use these, they often require an OAuth login in order to access the API.

This obviously isn't ideal if you don't want your users to have to log in to their Twitter/Facebook/Instagram account every time they view your app or website! Well, I've found a little bit of a workaround that may get you working with data in your front end without having to worry about stuff like OAuth. A few months back I needed to deliver a Designing With Data class and began experimenting with JQuery and JSON APIs. During that time I stumbled across this post about how to use a Google Spreadsheet as a live JSON. I'll split this tutorial in to two bits: Getting the data in to a Google Spreadsheet via IFTTT, and then pulling that data in to your app using JQuery.

Mapping murder throughout the world | News. Comparing murder rates of countries can really highlight the countries with problems - the ones in seriously need attention. A high murder rate gives a "tip off" that something needs to change. The UNODC have collected together all the national data on homicide for 207 countries. But of course nothing is ever simple when bringing together national statistics. Countries have different definitions of murder and the data is collected at different times and using different methods. All of this makes comparison of murder rates a messy business. But we can draw out important trends.

We have the full map for you to explore more easily. What does a high murder rate tell us about the country? There is a clear link between violent crime and development: crime hampers poor human and economic development; this, in turn, fosters crime. If this is the case then Honduras needs social and economic interventions fast, as does El Salvador and Cote d'Ivoire. Data summary Download the data More data.

The resources available for working with data and visualising it have become more numerous and more accessible in recent years. "We find ourselves in this perfect storm where suddenly journalists, everybody, is paying attention to data and the ability to collect data and create new data," Vizzuality's Andrew Hill told Journalism.co.uk earlier this year. Vizzuality created open source mapping tool CartoDB, and the team also set up "the map academy" where journalists can access free resources to learn more about online mapping.

Mapping can be a powerful storytelling tool, which journalists can use to take their audience on a journey following a narrative storyline, or to illustrate and make sense of fast moving breaking news events. Here is a list of 11 mapping tools reporters can use to add an extra dimension to their reporting and to build a more immersive experience for readers.

GeoFlow Takes Data for a 3-D Drive. In November, during the SharePoint Conference 2012, attendees received a Public Preview of project codename “GeoFlow” for Excel, the latest business-intelligence (BI) functionality to be integrated with Microsoft Excel 2013 later this year. As an Excel add-in, GeoFlow provides interactive, 3-D geospatial and temporal data visualizations. It enables information workers to discover and share new insights from data through rich, 3-D data on a globe and fluid, cinematic guided tours—virtual cinematography moving through data.

With dynamic data exploration that turns rows and columns of spatiotemporal data into rich 3-D maps, the term “add-in” really doesn’t do justice to the technology behind GeoFlow, a preview of which is available for download. Take a look under the hood, and you’ll see stars. But even while Curtis Wong, principal researcher at Microsoft Research Redmond, was busy giving talks about WWT, he had further ambitions in mind for the technology.
