Geographic Information Systems Specialists
GIS is basically a computer system that can assemble, store, manipulate, and display geographically referenced information. GIS specialists use this computer technology to combine mapmaking techniques with massive databases. The data are cataloged according to location, stored in map form, and analyzed as though they were a map rather than a list. The databases might include physical geographic data, demographics, census information, or epidemiology. Environmental planning and natural resource management find GIS particularly useful, but the techniques are now being applied to a variety of disciplines, including scientific investigations, homeland defense, and crime analysis.
