We will start with a brief history of mapping, and then look at some of the new ways we can nowadays use information traditionally shown on maps - SatNav systems, Web Mapping, Google Earth, Geographic Information Systems, etc. We will then look at the new technologies that make these new developments possible and consider a range of applications of geographical information systems including e-government, planning, the environment, transportation and location-based services and some of the ethical and societal issues involved. Hopefully there will be time to do a little crystal ball gazing. No previous knowledge will be assumed, but some level of familiarity with the Internet would be useful. The course will introduce a wide range of websites with geographical content. There will be a class website and in the final session members can present their own topics. This is an update of the course given last year.
