Satellite Survey Group Exercise: Research and Applications of Remote Sensing Data

In this class exercise, each group will focus on one of several satellites, including Landsat MSS, TM, 8 OLI, MODIS, AVHRR, WorldView-2, or SPOT-6. Teams will answer key questions about their chosen satellite's characteristics such as spatial, spectral, temporal, and radiometric resolution, costs, launch dates, data sources, and cessation of data collection. Additionally, each group will explore a practical application for their satellite's data. Finally, teams will collaborate to select suitable satellites for mapping land cover in the Saharan desert and assessing flood damage in Boulder, Colorado.

  1. Satellite Survey In-class group exercise

  2. Each group researches one of the following: • Landsat MSS • Landsat TM • Landsat 8 OLI • MODIS • AVHRR • WorldView-2 • SPOT-6

  3. Answer each of the following questions for your satellite(s) and record your answers in in a word file: • What is the spatial resolution(s)? • What is the spectral resolution? • What bands are included? • What is the temporal resolution? • What is the radiometric resolution? • What is the cost per km2? • When was it launched? • If not still collecting data, when did it stop? • Where do you get the data?

  4. Also… • Find one application of data from your satellite (but you don’t have to e-mail it to the class). • Be prepared to describe the application.

  5. When you have answered all questions, use WyoWeb to e-mail your answers to the entire class.

  6. After you receive the info from your classmates, with your group, decide which satellite(s) you would use for each of the following: You have been asked to accomplish two tasks: • Map the land cover of the southern margin of the Saharan desert in Africa as a baseline for future studies of land cover change resulting from possible climate change. • Map flood damage in Boulder, Colorado from the recent unprecedented rainstorm. Write down your answers and a brief justification, along with any questions you need to ask to make a better choice.
