In this investigation students explore how resolution affects information content on remotely sensed images, relate remote sensor resolution (pixel size) to information content, and gain an understanding of the information content of different kinds of remote sensing imagery. Students examine aerial or satellite images of the area around their school,interpret remotely sense images, and verify them using ground trotting techniques. Magnifying glasses (2x, 5x and 10x power), aerial photographs, plant identification manual, and a tape measure are needed supplies. This exercise is part of the Ground Truth Studies Teacher Handbook (GTSTH), and is a follow-up investigation to the Digital Faces activity of the same resource. GTSTH provides more than 20 activities to build student understanding of global change and remote sensing, and includes background chapters for teachers, glossary, and appendices.
