A geographic information system (GIS) is a computer program that captures, stores, checks, and displays data about locations on the Earth's surface. GIS may help individuals and organizations better understand geographical patterns and relationships by connecting seemingly unconnected data. GIS can use any information that includes location. The location can be expressed in many different ways, such as latitude and longitude, address, or ZIP code.
Web GIS is similar to the usual client/server three-tier architecture when it comes to executing GIS analysis operations. The geoprocessing is being broken out into server and client processes. Typically, a client is a web browser. A web server, web GIS software, and a database make up the server side.
This network paradigm is common in businesses, with some computers acting as servers and others as clients. To interact between the client and proprietary GIS software, the server simply runs proprietary GIS and adds a client interface on the client side and middleware on the server side.
