flickr_logo.pngFlickr just announced support for OpenStreetMap, the wiki-like mapping service that allows users to create and edit maps. Starting today, photos that are tagged with an OpenStreetMap node ID will include a link to OpenStreetMap (OSM) right underneath the photo. OSM assigns a random number to objects on its maps and Flickr can now read this number and also extract additional data about places from the OSM database. In addition, Flickr also announced that it will now support venue ID tags for the increasingly popular Foursquare service.

MapOSMatic est un service Web en Logiciel Libre qui vous permet de générer des cartes de villes en utilisant les données OpenStreetMap. La carte d'une ville est constituée de deux pages :

* la carte elle-même, découpée en carrés pour faciliter la recherche de rues ;

* un index des rues référencées selon les carrés de la carte.

Les cartes générées sont disponibles aux formats PNG, PDF et SVG et sont prêtes à être imprimées.

Les données utilisées pour la génération des cartes provenant d'OpenStreetMap, vous pouvez librement réutiliser, vendre, modifier, ... les cartes générées (en respectant la licence OpenStreetMap).

CloudMade helps you make the most of map data. We source our maps from OpenStreetMap, the community mapping project which is making a free map of the world. Our aim is to continue the democratization of geo data and to expand access to open geo data through a range of simple yet powerful tools and APIs.

OpenStreetMap.org’s RESTful API allows anyone to access data on their continually growing collaborative map of the world… in XML. This is great for most applications, but if you’re working in JavaScript (as we are), XML might as well be greek. We need JSON.

Google Maps are passé

The OSM rails app and tile rendering system were straightforward to take offline, and run locally. Walking Papers took some hacking. The print and scan storage was optionally disengaged from S3.

From GPS to pen and paper

Getting more people to contribute is crucial for any community-driven scheme, but particularly for maps – often associated with anorak-clad hikers waving GPS units. That's why a number of people are trying to come up with new ways to track information and get it into the system.

Beyond good enough? Spatial Data Quality and OpenStreetMap data

let's dream of a simple visual interface to get from OSM to an illustrator or inkscape file.

Open Street Map - Static API (Early Development)

"Main idea of the project is to create an web application which will provide an easy way of embedding maps into web pages. Application is going to be deeply configurable and easy to install by anyone on his server. It is being implemented in PHP5.

There is no going back to a world before Open Street Map and that is, in many ways, just as impressive as the actual "thing" they've created. One reason the Internets have always excited me is that they afford the possibility of building the world we want to live in so I am doubly happy when someone does.

LinkedGeoData is an effort to add a spatial dimension to the Web of Data / Semantic Web. LinkedGeoData uses the information collected by the OpenStreetMap project and makes it available as an RDF knowledge base according to the Linked Data principles. It interlinks this data with other knowledge bases in the Linking Open Data initiative.

The above map is styled dynamically in the browser using a javascript implementation of the core architecture of the open source mapnik library (ie Layers, Styles, Rules and Filters plus a couple of Symbolizers). (Implemented by eye-balling the XML and reading the wiki, mainly).

OpenStreetMap, the wiki-style map of the world that anyone can edit, is in need of a new way to add content. I've been working on a way to "round trip" map data through paper, to make it easier to perform the kinds of eyes-on-the-street edits that OSM needs now the most, as well as distributing the load by making it possible for legible, easy notes to be shared and turned into real geographical data.

Walking Papers is a working service that implements this paper idea, based on initial technical experimentation from back in February.

I've been experimenting with some javascript classes that mimic the structure of mapnik's Layer/Style/Rule classes and render OSM data (via GeoJSON) to a <canvas> element. I've also finally taken a look at how github works, so I've decided to share the initial code there in case people are interested. If you don't want to check the code out for yourself there's a demo page here (tested in Firefox and Safari only, so far).

Print maps, draw on them, scan them back in and help OpenStreetMap improve its coverage of local points of interests and street detail.

pdate for TrailRunner, the outdoor oriented route-planning and journaling software for Mac OS X. This major milestone release now adds a routing feature based on openStreetMap,

The speedy success of the hardware appeal (target reached in less than three days) was pretty impressive, but what really perked my (PostgreSQL fanboi) ears up was the news that the new hardware was going to run PostgreSQL, instead of the MySQL database OSM has used from the start. As of April 19, OSM is running their new API live on PostgreSQL.

Lars Ahlzen worked up a beautiful online topographic map of the entire state of Massachusetts using data from OpenStreetMap and MassGIS, and only free and Open Source tools.

ideally all data in the public interest should be released in a format that is easily consumable by third-party applications.

Un petit bookmarklet pour passer de Google Maps à OpenStreetMap en un clic. (Ne cliquez pas dessus et lisez la suite)

The OSMTrack application is designed for people who would like to contribute to OpenStreetMap development. It is not a personal tracking application.
