They are tools that allow users to create interactive queries, analyze spatial information, edit data, maps, present the results of all these operations. This article describes the basic concepts of these systems. Likewise, the forms of data representation are shown, as well as the use of the main current spatial database software. Several works that establish comparisons between the main geographic information systems of the market are analyzed. Finally, the use of geographic information systems in agriculture is addressed.]]></p></abstract>
