Document Summary
The major technological advance of the late 20th century in this regard was one that, although not specific to geography in its wide range of applications, has had particular resonance for geographers. Geographic information systems (gis) are combined hardware and software systems for the capture, storage, checking, integration, manipulation, display, and analysis of spatially referenced (geocoded) data. The data (i. e. , information with coordinate referencing, such as latitude and longitude) are input into these systems and displayed in two- or three- dimensional maps and other diagrammatic forms. Two or more maps can be overlaid and integrated for analysis-such as a relief map and a map of wells-even if they are compiled on different spatial grids. If geocoding schemes can be made compatible, separate data sets can be combined, analyzed, and displayed. This is technically demanding in many circumstances because of the issues involved in the interpolation of values for particular points from partial data.
