Calibration - GIS Wiki | The GIS Encyclopedia

HistoryCalibration Versus MetrologyBasic Calibration ProcessAdditional InformationQualityCalibration of InstrumentsInternationalSee AlsoExternal LinksFurther ReadingMany of the earliest measuring devices were intuitive and easy to conceptually validate. The term "calibration" probably was first associated with the precise division of linear distance and angles using a dividing engine and the measurement of gravitational mass using a weighing scale. These two forms of measurement alone and their direct derivatives supported nearly all commerce and technology development from the earliest civilizations until about 1800AD. The Industrial Revolution introduced wide scale use of indirect measurement. The measurement of pressure was an early example of how indirect measurement was added to the existing direct measurement of the same phenomena. Before the Industrial Revolution, the most common pressure measurement device was a hydrostatic manometer, which is not practical for measuring high pressure. Eugene Bourdon filled the need for high pressure measurement with his Bourdon tube pressure gage. In the direct reading hydrostatic manometer design on t...Get price

Geographic information system - Wikipedia

History and DevelopmentTechniques and TechnologySpatial Analysis with GISApplicationsSemanticsImplications of GIS in SocietyFurther ReadingThe phrase, "geographic information system", was coined by Roger Tomlinson in 1968, when he published the scientific paper, "A Geographic Information System for Regional Planning". Tomlinson, acknowledged as the "father of GIS", is credited with enabling the first computerized–GIS to be created through his work on the Canada Geographic Information Systemin 1963. Ultimately, Tomlinson created a framework for a database that was capable of storing and analyzing huge amounts of data; leading to the Canadian government being able to implement its National Land-Use Management Program. One of the first known instances in which spatial analysis was used, came from the field of epidemiology in the, "Rapport sur la marche et les effets du choléra dans Paris et le département de la Seine" (1832). French geographer and cartographer, Charles Picquet, created a map outlining the forty-eight Districts in Paris, using halftone color gradients, to provide a visual representation for the number of r...Get price
