Geographic information system
A Geographic Information System (GIS) is an organized set of (i) geolocated (also georeferenced) datasets in different formats, (ii) computer hardware, software, applications, and procedures that allow data capture, storage, and processing (Kennedy 2001), and (iii) people involved in using the system. These components once combined enable effective usage of geolocated data for finding answers and solutions to spatially based challenges. GIS is an integral part of the Geographic information technology that uses computer-based tools to analyze spatial information (Leblon 2013). The key advantage of GIS is that it offers summarized geographically related replies to the end-users’ questions related to space such as “Where is it?” “What is it?” “Object’s shape and relation to neighbors?” “Object’s change through time?” and “What if…?”
In a general sense, the term GIS describes any information system that integrates, stores, edits,...
