graphics.,26/32,GIS germinated in the early 1960s,by the,Canada Roger F.Tomlinson,and the United States,Duane F.Marble,in different places from different angles.The former aimed at land use,established the Canada Geographic Information System(CGIS)at Canada Land Survey Bureau,while the latter research on large-scale urban transport at the Northwestern University of the United States,and proposed the establishment of GIS software systems thinking.,27/32,Seeing from GIS development history,advances to a higher level every decade:,1960s,：,Pioneering stage of development,.Computer-aided Mapping,and Analysis of Operator,1970s,：,Consolidation phase,.Large capacity,graphical HCI(Human-Computer Interaction),1980s,：,Breakthrough stage,.Microcomputer GIS software products,application extended.,1990s,：,Socialization stage.,Spatial information industry,WebGIS,21th Century,：,Spatial Information Infrastructure(SII),.Digital City,Digital Earth,28/32,Points 5 Relationship of GIS to other fields,29/32,The Highly Integrated 3S Technology,The integrated applications of,GPS,GIS,and,RS,constitute a whole,real-time and dynamic Earth observation,analysis and application operating system.,The interaction between the three formed a one brain,two eyes framework,namely,RS and GPS provide or update the regional information and spatial location for GIS.And GIS does the corresponding spatial analysis,to extract useful information from a broad array of data provided by RS and GPS,and then do prehensive integration so that it will become the scientific basis for decision-making.,30/32,In 3S technology integration,GPS rapidly provides the spatial location of the objects in real-time.RS quickly provided the information of a large area of surface objects and their various changes in real-time.GIS is the comprehensive processing and application analysis platform for Spatio-temporal data from multiple.,31/32,United States Cruise Missiles and Patriot Missiles installed the 3S integrated system,can achieve automatic navigation,automatic tracking,automatic target identification,to carry out an accurate interception and hit.,32/32,
