In this topic we will examine the role of remotely sensed data for mapping and monitoring the Earth. Your main task is to make a critical evaluation of case studies for different applications and on completing this topic you should better characterise remote sensing as a source of geospatial information. As you work through the material you should gain the knowledge to enable you to address the following questions:

  • How is remote sensing contributing to local, regional and global studies of the Earth?
  • What are the strengths and weaknesses of Earth observation by remote sensing?
  • How and why is the industry surrounding remotely sensed data developing?
