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

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

Making Image Overlays Easy with GGroundOverlay and GGeoXML (via) Surprisingly, there doesn’t appear to be a good online tool for helping align an overlay image with a Google Map and exporting the result as a KML file. This is the best I could find—Yahoo! used to have a tool called MapMixer but it doesn’t seem to exist any more. # 30th July 2009, 10:58 pm

Announcing Google Maps API v3. Sounds like a complete rewrite, with performance as the key goal. Only a developer preview at the moment, but my favourite feature is that API keys are no longer required. # 28th May 2009, 1:22 am

Google Maps Data API (via) I’m disappointed by this one—it’s really just a CRUD store for the KML files used in Google MyMaps. It would be a lot more useful if it let you perform geospatial calculations against your stored map data using some kind of query API—a cloud service alternative to tools like PostGIS. # 20th May 2009, 9:07 pm

AJAX APIs Playground. Ferociously useful collection of executable and editable example code for all(?) of Google’s JavaScript APIs, including Google Maps and the increasingly interesting Visualization API. # 22nd January 2009, 6:38 pm
