Earth Observation Day

Earth Observation Day (EOD) is a STEM educational outreach event of AmericaView and our partners. EOD will be celebrated officially on Wednesday, October 14, 2015. The goal is to engage students and teachers in remote sensing as an exciting and powerful educational tool.

During 2013, teachers and AmericaView scientists worked with the GLOBE SATELLITES program to explore the surface temperature of two common types of land cover, asphalt and grass, using Landsat satellite data and measurements taken by students. The idea was to explore patterns of surface temperature as they relate to Earth’s energy budget. Land cover influences a wide range of important socio-economic and ecological conditions, including local climate, air and water quality, human health and wellness, soil permeability and productivity, stream flow and runoff, and wildlife habitat, to name a few. Mapping land cover using free Landsat data, along with surface temperature measurements, comprise engaging, standards-based exercises that introduce remote sensing technology and critically important spatial thinking skills, fostering a richer, more interesting, and more powerful scientific and cultural understanding of the local environment.

A tutorial covering how to access free Landsat and other remote sensing data is available here.

Why Landsat Images?

landcover_mtownLandsat images date back to 1972 and are the longest, most comprehensive set of satellite data of Earth and its features. The images are an exciting and freely available educational resource for teachers of all levels. Landsat images and derived products such as land cover maps (for example, at right), surface temperature maps, tree canopy maps, and soil permeability maps can be used in a wide variety of STEM disciplines including the physical and life sciences. Landsat images also support exploration and investigation in interdisciplinary subjects such as geography, social studies, political science, even history. Thus, land cover mapping using free Landsat imagery helps to meet science content standards and objectives in Physical Science, Life Science, Geography (including critically important spatial thinking skills), as well as Inquiry Standards and 21st Century Learning objectives.

Support for Teachers and How to Get Involved

wv_grafton_hs_small_4One of the unique features of Earth Observation Day is that AmericaView scientists, all of whom are experts in remote sensing and related geospatial technologies, are available to support teachers in their respective states. Pre-service teachers learning to use GPS receivers during an Earth Observation Day event in West Virginia. Support can come in various ways, either by answering questions about the lessons and activities, or by pointing teachers toward other resources, or by offering to talk with students in the classroom. AmericaView scientists are committed to helping their state’s K-12 teachers as they expand their horizons and begin to integrate remote sensing as a fun, informative, and engaging teaching tool in their classrooms.  For information about K-12 use of Landsat images on Earth Observation Day, October 14, 2015, contact by email or call him at 724-938-4255.
