Space Facts II - Improved Mapping Of Roads From Space

The video discusses a mobile mapping system that uses satellite signals to create accurate and up-to-date digital maps. This technology, developed by NASA researchers, allows for precise location tracking and road mapping by maintaining contact with navigational satellites. The digital format of the maps facilitates computer processing, aiding governmental agencies in highway management and decision-making. The system also simplifies data collection on highway features and has potential applications for mapping other planets in the future.
