I've mentioned the KOKAE resource before on my Google Earth page, but for those who don't know, it's a series of video resources based on Google Earth.
A session was delivered to the GA Conference in April 2007 by Richard Treves, and this is now available for you to view HERE. This includes all details of the talk and lots of other materials. A very helpful resource.
I was unable to attend this session as I was delivering our 2 hour workshop on GIS, delivered by members of the GA Secondary Committee at the time.
The materials from the GA Conference are now appearing on the website.
There's plenty more of Geographical interest there...
