Question

Quizplus · Accepted Answer

A GIS is a system that integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information. While remote sensing and thermal scanners can provide data for GIS, GIS is ultimately based on the use of a computer to organize and analyze spatial data. The electromagnetic spectrum is also relevant to GIS, as it includes the range of wavelengths of electromagnetic radiation used in remote sensing technology, but it is not the primary basis for GIS.
