GIS are tools that allow users to create interactive queries, analyze spatial information, edit and update a database and edit maps. Thus, in its simplest terms, GIS is the merging of cartography and database technology. Generally, GIS applications were used to display the different phenomena that have a spatial location in the physical environment. Now, with advances in technology, data management and subsequent availability, GIS technology has the ability to be integrated more effectively applied to the provision of services, evaluation, decision making for better land management.
