This course examines how innovative earth observation and other geospatial technologies allow us to better understand the changing Earth, including how humans are impacting the planet and interacting with the environment and each other. The course will cover a range of space-based technologies such as the use of remote sensing, global positioning systems, location-based services, virtual globes (like GOOGLE EARTH), web-based mapping and big-data geospatial analysis. A range of environmental change applications will be covered and the use of remote sensing and GIS to examine these changes demonstrated. Focus will be on forest cover and change. The course will introduce computer-based skills and techniques for spatial thinking, image interpretation, and environmental decision-making as well as time for reflection on the images and how they can be used to inspire the general public.
