Oakland crime maps XI: how close, and how bad? Michal Migurski’s experiments with heat maps for Oakland Crimespotting, using OpenStreetMap data as that allows him to position his heat map layer underneath the street labels, keeping them legible. # 30th December 2008, 10:16 am

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

HeatMapAPI (via) Cool (or should that be hot?) API for adding heat maps to any Google Maps application. # 19th July 2008, 11:46 pm

OSM routing, A*, cycle-filtered, python (via) A python library for finding routes using OpenStreetMap data. # 5th July 2008, 3:13 pm

Berlin Zoo on OpenStreetMap. Someone has added all of the animal enclosures in Berlin Zoo (with German animal names) to OpenStreetMap. # 5th July 2008, 3:07 pm

Dopplr place googlemaps, with and without Yahoo Geo API bounding box adjustment. Dopplr uses Geonames for most geo information, but is now mixing in bounding box data from the Yahoo! Geo web service to improve the default zoom level for their maps. The JSON callback API means no server-side code is required on Dopplr’s end. # 17th May 2008, 11:35 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

About our maps. Why and how EveryBlock rolled their own maps. # 5th March 2008, 1:05 am

Google Maps Without the Scripting. Google Maps has finally added a simple API for retrieving static map images. # 4th March 2008, 11:54 pm
