Polymaps. Absurdly classy: “a JavaScript library for image- and vector-tiled maps using SVG”. It can pull in image tiles from sources such as OpenStreetMap, then overlay SVG paths specified using GeoJSON. The demos make use of GeoJSON tiles for US states and counties hosted on AppEngine. The library is developed by Stamen and SimpleGeo, and released under a BSD license. SVG support in the browser is required. # 20th August 2010, 6:46 pm

Tile Drawer (via) The most inspired use of EC2 I’ve seen yet: center a map on an area, pick a Cascadenik stylesheet URL (or write and link to your own) and Tile Drawer gives you an Amazon EC2 AMI and a short JSON snippet. Launch the AMI with the JSON as the “user data” parameter and you get your own OpenStreetMap tile rendering server, which self-configures on startup and starts rendering and serving tiles using your custom design. # 26th August 2009, 9:32 am

Static Maps API v2. The new version of the Google Static Maps API (static images generated using arguments in a URL, no JavaScript required) adds support for paths, areas and automatically geocoding addresses to specify locations of markers and the centre of the map. # 26th August 2009, 9:01 am

Best of OpenStreetMap (via) I keep on telling people OpenStreetMap is this year’s Wikipedia—at its best, it beats commercially available maps. This “best of” site highlights the areas where OSM really shines (the yellow stars)—the German mapping community in particular have produced some outstanding cartography. # 13th August 2009, 12:30 pm

cascadenik: cascading sheets of style for mapnik. Great idea. Mapnik (the open source tile rendering system used by OpenStreetMap and others) has a complex style configuration based on XML. Michal Migurski has build a CSS-style equivalent which compiles down to XML, hopefully making it much quicker and easier to get started with Mapnik customisation. # 30th August 2008, 10:04 am

Around the world and back again. Flickr are using data from OpenStreetMap to provide street-level detail of Beijing for the Olympics. # 13th August 2008, 11:05 pm
