About this tutorial

Educational Objectives

After completing several of the activities in this tutorial, the student:

  • will be familiar with the basic concepts of .remote sensing. technology;
  • will be able to recognize/interpret some features in satellite images;
  • will be able to describe how remote sensing contributes to monitoring the environment.

Content

The material in this tutorial makes use of Canadian examples of environmental monitoring.

Presentation of the Material to Students

Sections 2.1, 2.2 and 2.3 should be carefully examined by the students. Sections 4.1, 4.2, 4.3 are intended as additional reading; Appendices A, B, and C, may be useful resources while working on the activities. The answers are found in Appendix D. The activities in Section 3 are presented in a recommended order.

Level of Difficulty

These activities and exercises are intended for children aged 11 and up. Some of the activities will be more suitable for older children. Length of time required for each activity varies between 5 and 30 minutes.

Format

It is anticipated that this tutorial will be used in a classroom setting. The activities can be completed by students working either individually or in small groups. This tutorial is intended for use as a printed copy.

Considerations Regarding Printing

The tutorial pages should be printed on a colour printer. Please use the best quality colour printer and paper that is available and check the results to ensure that features referred to in the exercises are indeed visible in the printed version.

Prerequisite Knowledge

The student should be familiar with:

  • Cartesian co-ordinates (x, y) for referencing locations of features in the imagery;
  • the cardinal points of the compass;
  • map reading.
  • See Appendices for descriptions of Cartesian co-ordinates, points of a compass and the dot grid technique for measuring area.
