Here's the recent open source / open data geonews covering the last two weeks.
Google's Ed Parsons has an entry on the proposal of the International Cartographic Association (ICA) to establish a commission on neocartography.
From the entry: "Many examples of new and innovative mapping are being produced outside the normal orbit of existing cartographers or map producers. The term neocartographers is being used to describe map makers who may not have come from traditional mapping backgrounds, and are frequently using open data and open source mapping tools. Another difference is in the blurring of boundaries between map producers and map consumers. The availability of data and tools allows neocartographers to make their own maps, show what they want, and often be the intended audience as well – that is to say they may make the maps for themselves, just because they can. There is a real need for a discipline to be established to study this essentially undisciplined field of neocartography."
