Cartographer.js. “Thematic mapping for Google Maps”—which means an easy way of adding heat maps (aka chloropleths), pie charts and point clusters as a layer over a Google map. # 1st November 2009, 1:20 pm

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

OSM Super-Strength Export. Awesome new feature on OpenStreetMap: you can browse to anywhere on the map, then hit “export” and download a rendered bitmap or vector (PDF and SVG) image of the currently displayed map—and because it’s OSM there’s no watermark and a very liberal usage license. # 22nd April 2008, 9:56 am

KML: A new standard for sharing maps. Google’s KML format, which is already supported by both Microsoft and Yahoo!’s map software, has been accepted under the wing of the Open Geospatial Consortium and is now an international standard. # 14th April 2008, 6:36 pm

London Connections. Marvellously obsessive blog about the vagaries of London transport, including some really nice custom created maps. I love detailed maps of tube stations; anyone know a good place to find them? # 2nd April 2008, 8:53 pm

Information Freeway (via) Really lovely interface to Open Street Map, sadly suffering from a horribly vague name and almost no publicity at all. # 14th October 2007, 11:58 pm

Multimap API: Decluttering Markers (via) V1.2 of the Multimap API is out, and the nicest new feature is automatic decluttering of close-together markers. # 14th February 2007, 11:30 am
