By completing this topic you should have gained the knowledge and image processing skills to answer the following questions and complete the following tasks:

  • what is the relationship between the nature of land cover variation and the frequency of EO data acquisition?
  • why calibrate EO data in multitemporal image processing?
  • construct and visualise change in the time-profiles, multitemporal feature space and image space,
  • implement techniques to detect and characterise change and interpret the results of those techiques,
  • critically assess the strengths and weaknesses of techniques to extract information in the temporal domain
  • what are the prospects for improving multitemporal image processing?
