Andy of Digital Urban is at the American Association of Geographers conference from where he writes about an education project using Google Maps.
What I wonder is why the author spent all that time programming these pages rather than just collating them in GEarth and getting the students to analyse the data within GEarth? It certainly would have saved him a lot of time and I think putting some of the images in pop up balloons would have made better sense. Having said that, There is an issue of running GEarth on student machines - GMaps is lighter on computing power which may be important for the students concerned.
Andy notes that GEarth, GMaps and neo-geography are still niche areas of discussion at the conference. I've been to AGU fall meeting for the last couple of years and its got a much higher profile there.
