An automated system for the capture, storage, retrieval, analysis, and display of spatial data. Computer-based mapping, analysis, and retrieval of location- based data. Giss are simultaneously the telescope, the microscope, the computer, and the xerox machine of regional analysis and synthesis. a system that includes computer software, hardware and personnel (human- ware) to help manipulate, analyze, and present geographic information. Location intelligence -> location matters: data collection. Doubled in the last 50 years -> over 7 billon. Past 300 years, humans have permanently altered most of earth surface.
