This article will demonstrate an approach for discovering and assessing local landscape change through the use of remotely sensed images. A brief introduction to remotely sensed imagery is followed by a discussion of relevant ways to introduce this technology into the college science classroom. The Map Detective activity demonstrates the integration of remotely sensed imagery into introductory-level geography courses by illuminating elements of human and physical landscape change via analysis of a series of historical aerial photographs.
