Traditionally GIS was run on computer system where people capture store, analyse information pertaining to land. The concept of GIS and its applications were first used by Canadian expert Roger Tomlinson during the 1960's when he used it to collect, store and analyze data about Canada's land use patterns. After this during the decades of 1970's and 1980's several national agencies of many countries started using GIS information for various land use purposes. It was during this phase that GIS technology started to evolve rapidly improving the quality and usability of technologies. Throughout the 1990's software companies started making various desktop applications for the purpose of doing GIS research. ArcGIS, MapInfo, ArcView, GeoViewer among many other software applications were created for the public, government agencies to extract information about land use patterns. Businesses also started to use GIS information to know about the usability of land and also to know the distribution of not only their customers but also suppliers of resources and raw materials.THE VARIOUS APPLICATIONS OF GIS:GIS uses many types of data to reveal insights and patterns that help people and organizations in everything, from urban planning, environmental conservation, and disaster response to healthcare and even marketing. At present the GIS market is valued to be around 10 Billion USD and is expected to rise around 18 Billion by 2023. GIS and its applications span nearly in all conceivable fields. This growth is mainly due to investments in homeland security by both developed and developing nations, and also immense capital funding in urban development.Urban Planning: At present times, urban planning accompanied with the use of GIS has immense applications. GIS helps surveyors, engineers and urban architects to not only design, map and expand the cities wherever possible but it also helps to determine illegal encroachment of land, detect urban areas vulnerable to disaster among many other such applications. The "smart cities" also heavily rely on GIS data for the purpose of development of infrastructure and services.THE CONCEPT OF GIS AND ITS APPLICATIONS WERE FIRST USED BY CANADIAN EXPERT ROGER TOMLINSON DURING THE 1960'S WHEN HE USED IT TO COLLECT, STORE AND ANALYZE DATA ABOUT CANADA'S LAND USE PATTERNS
