1. Ans: A geographic information system (GIS) is a system that creates, manages, analyzes, and maps all types of data. GIS connects data to a map, integrating location data (where things are) with all types of descriptive information (what things are like there). This provides a foundation for mapping and analysis that is used in science and almost every industry. GIS helps users understand patterns, relationships, and geographic context. The benefits include improved communication and efficiency as well as better management and decision making.
2.Ans: The five components of GIS establish a fundamental framework upon which all types of geographically referenced information may be logically assembled and scientifically explored. Consisting of people, methods, data, software and hardware, the five components of GIS form a foundation that empowers users to analyze, visualize and improve an incredibly diverse spectrum of real-world issues. In the following paragraphs, the five components of GIS are explored in greater detail
