If you step through this prezi presentation to the end you can see:
- My bullet points for the lecture
- To the right of the bullet points for each one I've added some commentary that you have to zoom into to read
- below the bullet points is a YouTube video walkthrough (links Gemma, Digimap) for each one except Google Earth which has a link to an earlier tutorial of mine. Note that the digimap one assumes you're a Southampton Uni student so can sign into the service.
Prezi maps: You might also like to follow the prezi through, I link to some of my favourite maps and there's commentary on most of them (in the form of the same small scale writing to the right) too.
