Geographic information: information about places on the earth"s surface, knowledge about.

Definitions: database system set of operations system designed to deal with spatial data, helps solve complex planning and management problems input, data management (data storage and retrieval), manipulation and analysis, output. Time is also a factor, since things change with time. Why use it: use of spatially referenced data. Data whose location is known in a specific coordinate system: graphical and attribute data input and editing there is more crowdsourcing now, selective spatial and attribute query, specialized spatial analysis tools.
