Landsat TM image has a resolution of 30 m. A 1-ha plot (100 m x 100 m) would be equivalent to approximately 9 pixels (a square of 3 pixels by 3 pixels). School biodiversity plots are only 20 m2.) 5. Ask students what factors might affect the use of satellite images. (Cloud cover, for example, can reduce the detail obtained from a Landsat image.) EXTENSIONS 1. Repeat the above activity with a satellite image of your school site, (which should be available from the USGS web site) and a local topographic map

Teacher Guide 15 A c ti v it y 3 L <span class="highlight">an</span> d C ov er M ap pi ng OVERVIEW Thinking more globally, how do scientists assess biodiversity <span class="highlight">for</span> large regions? In this activity, students emulate scientists by using a <span class="highlight">satellite</span> <span class="highlight">image</span> to determine different land cover types <span class="highlight">and</span> create a land cover map <span class="highlight">of</span> Front Royal, Virginia. OBJECTIVES Students will be introduced to remote-sensing techniques <span class="highlight">and</span> their applications in monitoring forest biodiversity. Students will visually interpret a <span class="highlight">satellite</span> <span class="highlight">image</span> (as opposed to

Although remote-sensing techniques hold great promise <span class="highlight">for</span> extending our understanding <span class="highlight">of</span> biodiversity to a global level, scientists using <span class="highlight">satellite</span> data to identify forests <span class="highlight">and</span> other vegetation only now are able to reliably achieve the level <span class="highlight">of</span> detail necessary <span class="highlight">for</span> biodiversity studies. Interpretation <span class="highlight">of</span> vegetation is complicated by seasonal variations, environmental factors, <span class="highlight">and</span> health <span class="highlight">of</span> the vegetation. Transitional zones <span class="highlight">and</span> climatic gradients make
