The Geospatial Revolution examines the world of digital mapping and how it is changing the way we think, behave, and interact. Geospatial information influences nearly everything. Seamless layers of satellites, surveillance, and location-based technologies create a worldwide geographic knowledge base vital to the interconnected global community. The Geospatial Revolution explores compelling human stories that explain the history, applications, related privacy issues, and impact of location-based technologies including GPS and GIS. The video episodes are useful for teaching history, social studies, geography, environment and ecology, science and technology, and for learning about career development.
