Cet atelier pratique pensé comme une formation – gratuite et accessible à tous – a permis au public présent de rentrer de plain-pied dans la collecte et la création collective de données. Petite fabrique de services urbains Parmi les actions portées par le programme Montpellier Territoire Numérique, l’initiative d’ un portail open data a permis de récolter déjà plus de 50 jeux de données. Ces données publiques facilement téléchargeables sont mises à disposition pour permettre aux citoyens, entreprises, associations, d’innover et de créer des services urbains pour leur lieu de vie .

Introduction This tutorial is on how to lookup and geocode places in a Wikipedia article and visualize those with the help of Processing. It gives a basic overview on the related topics, and provides mutiple Processing examples, below. This brief article, as well as the examples were created for the GeoWiki workshop at the Interface Design department of FH Potsdam . Placemaker Yahoo Placemaker is a "geoparsing web service" that enrichs content with geographic metadata by extracting places from unstructured texts.
This page presents a variety of calculations for latitude/longitude points, with the formulæ and code fragments for implementing them. All these formulæ are for calculations on the basis of a spherical earth (ignoring ellipsoidal effects) – which is accurate enough * for most purposes… [In fact, the earth is very slightly ellipsoidal; using a spherical model gives errors typically up to 0.3% – see notes for further details]. Distance This uses the ‘ haversine ’ formula to calculate the great-circle distance between two points – that is, the shortest distance over the earth’s surface – giving an ‘as-the-crow-flies’ distance between the points (ignoring any hills, of course!). The haversine formula 1 ‘remains particularly well-conditioned for numerical computation even at small distances’ – unlike calculations based on the spherical law of cosines . The ‘versed sine’ is 1-cosθ, and the ‘half-versed-sine’ (1-cosθ)/2 = sin²(θ/2) as used above.

Download Style from GitHub Acetate is a new way of thinking about basemap tiles. Made in conjunction with Stamen Design and 41 Latitude, it allows you to layer pieces of the basemap throughout your visualization. We think what we came up with is quite beautiful, but if it’s not to your tastes all the stylesheets and code is opensource so you can roll your own. For developers, GeoIQ has released the stylesheets and code to create the Acetate tiles.

There’s an increasing amount of useful packages that allow for spatial analysis in python. Having said that, actually drawing a map remains relatively tricky, here I am sharing a few of the methods that I have come up with recently to help in this area. Firstly, let’s consider the basic set of prerequisites that you should have installed to do some useful things in Python. Numpy and Scipy – easy_install Numpy / easy_install Scipy Numeric Python and Scientific Python vastly extend the scientific programming capabilities of Python. Numpy adds the array() object which, for numeric matters, is far superior to the standard Python List, as well as numerous mathematical methods.

Over the past few months we have been harvesting geospatial data from Twitter with the aim of creating a series of new city maps based on Twitter data. Via a radius of 30km around New York, London, Paris, Munich we have collated the number of Tweets and created our New City Landscape Maps.
