The acronym GIS is sometimes used for geographic information science GIScience to refer to the academic discipline that studies geographic information systems1 and is a large domain within the broader academic discipline of geoinformatics. What goes beyond a GIS is a spatial data infrastructure, a concept that has no such restrictive boundaries. In general, the term describes any information system that integrates, stores, edits, analyzes, shares, and displays geographic information. GIS applications are tools that allow users to create interactive queries user created searches, analyze spatial information, edit data in maps, and present the results of all these operations. Geographic information science is the science underlying geographic concepts, applications, and systems. GIS can refer to a number of different technologies, processes, and methods. It is attached to many operations and has many applications related to engineering, planning, management, transportlogistics, insurance, telecommunications, and business. For that reason, GIS and location intelligence applications can be the foundation for many location enabled services that rely on analysis and visualization. GIS can relate unrelated information by using location as the key index variable. Locations or extents in the Earth spacetime may be recorded as datestimes of occurrence, and x, y, and z coordinates representing, longitude, latitude, and elevation, respectively. All Earth based spatialtemporal location and extent references should be relatable to one another and ultimately to a real physical location or extent. This key characteristic of GIS has begun to open new avenues of scientific inquiry. History of developmenteditThe first known use of the term geographic information system was by Roger Tomlinson in the year 1. A Geographic Information System for Regional Planning. Tomlinson is also acknowledged as the father of GIS. Previously, one of the first applications of spatial analysis in epidemiology is the 1. Rapport sur la marche et les effets du cholra dans Paris et le dpartement de la Seine. The French geographer Charles Picquet represented the 4. Paris by halftone color gradient according to the number of deaths by cholera per 1,0. In 1. 85. 4 John Snow determined the source of a cholera outbreak in London by marking points on a map depicting where the cholera victims lived, and connecting the cluster that he found with a nearby water source. This was one of the earliest successful uses of a geographic methodology in epidemiology. While the basic elements of topography and theme existed previously in cartography, the John Snow map was unique, using cartographic methods not only to depict but also to analyze clusters of geographically dependent phenomena. The early 2. 0th century saw the development of photozincography, which allowed maps to be split into layers, for example one layer for vegetation and another for water. This was particularly used for printing contours  drawing these was a labour intensive task but having them on a separate layer meant they could be worked on without the other layers to confuse the draughtsman. This work was originally drawn on glass plates but later plastic film was introduced, with the advantages of being lighter, using less storage space and being less brittle, among others. When all the layers were finished, they were combined into one image using a large process camera. Once color printing came in, the layers idea was also used for creating separate printing plates for each color. While the use of layers much later became one of the main typical features of a contemporary GIS, the photographic process just described is not considered to be a GIS in itself  as the maps were just images with no database to link them to. Computer hardware development spurred by nuclear weapon research led to general purpose computer mapping applications by the early 1. The year 1. 96. 0 saw the development of the worlds first true operational GIS in Ottawa, Ontario, Canada by the federal Department of Forestry and Rural Development. Developed by Dr. Roger Tomlinson, it was called the Canada Geographic Information System CGIS and was used to store, analyze, and manipulate data collected for the Canada Land Inventory  an effort to determine the land capability for rural Canada by mapping information about soils, agriculture, recreation, wildlife, waterfowl, forestry and land use at a scale of 1 5. A rating classification factor was also added to permit analysis. CGIS was an improvement over computer mapping applications as it provided capabilities for overlay, measurement, and digitizingscanning. It supported a national coordinate system that spanned the continent, coded lines as arcs having a true embedded topology and it stored the attribute and locational information in separate files. As a result of this, Tomlinson has become known as the father of GIS, particularly for his use of overlays in promoting the spatial analysis of convergent geographic data. CGIS lasted into the 1. Canada. It was developed as a mainframe based system in support of federal and provincial resource planning and management. Its strength was continent wide analysis of complex datasets. The CGIS was never available commercially. In 1. 96. 4 Howard T. Fisher formed the Laboratory for Computer Graphics and Spatial Analysis at the Harvard Graduate School of Design LCGSA 1. SYMAP, GRID, and ODYSSEY  that served as sources for subsequent commercial developmentto universities, research centers and corporations worldwide. By the late 1. 97. GIS systems MOSS and GRASS GIS were in development, and by the early 1. The Sims 3 Base Game Iso here. M S Computing later Intergraph along with Bentley Systems Incorporated for the CAD platform, Environmental Systems Research Institute ESRI, CARIS Computer Aided Resource Information System, Map. Info Corporation and ERDAS Earth Resource Data Analysis System emerged as commercial vendors of GIS software, successfully incorporating many of the CGIS features, combining the first generation approach to separation of spatial and attribute information with a second generation approach to organizing attribute data into database structures. In 1. 98. 6, Mapping Display and Analysis System MIDAS, the first desktop GIS productcitation needed was released for the DOS operating system. This was renamed in 1. Map. Info for Windows when it was ported to the Microsoft Windows platform. This began the process of moving GIS from the research department into the business environment. By the end of the 2. GIS data over the Internet, requiring data format and transfer standards. More recently, a growing number of free, open source GIS packages run on a range of operating systems and can be customized to perform specific tasks. Increasingly geospatial data and mapping applications are being made available via the World Wide Web see List of GIS software  GIS as a service. Several articles on the history of GIS have been published. GIS techniques and technologyeditModern GIS technologies use digital information, for which various digitized data creation methods are used.
