Based on the information you read in the “what is gis? ” article, describe the purpose and function of gis. your answer should be one or two short paragraphs.

A GIS, or geographic information system, is a system that helps people understand local geography. According to the article, GIS “is a computerized data management system used to capture, store, manage, retrieve, analyze, and display spatial information.”

A key feature of a GIS is that it allows users to combine different types of data for the same geographical region. Some examples of geographical data that a GIS can store are terrain features, climatic conditions, soil quality, and population. GIS software is useful in managing land resources and monitoring the environment. It can help government agencies plan effectively for urban development and other projects.

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.[3][4] Geographic information science is the science underlying geographic concepts, applications, and systems.[5]

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, transport/logistics, insurance, telecommunications, and business.[4] 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 space–time may be recorded as dates/times of occurrence, and x, y, and z coordinates representing, longitude, latitude, and elevation, respectively. All Earth-based spatial–temporal 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.
