For the fourth year in a row, the author and a computer teacher have joined forces to guide students through an annual technology and research project that benefits area institutions and community members. The author presents the three key areas of the geospatial technologies curriculum at Douglas High School in Box Elder, South Dakota: (1) Geographic Information System (GIS); (2) Global Positioning System (GPS); and (3) remote sensing theory. GIS is digital mapping and analysis software that integrates data from many sources, including location data from GPS satellites orbiting Earth. The author states that students embrace these technologies enthusiastically in both computer science and science classes, but as with so many classroom projects, application is necessary to make learning relevant.
