DefinitionGIS data (GISデータ) is the general term for data tied to locations on a map and handled in a geographic information system (GIS).
ExplanationGIS is a system that overlays location-based data on a map and analyzes distribution and distance. For instance, layering surrounding population and road data over store locations helps when deciding where to open a new store. A shapefile is one of the formats used to store such data.
AnalogyPicture laying several transparent sheets showing population and roads over a blank map and comparing them, except a computer does the work.
Memory hookGIS stands for Geographic Information System, and the word Geographic is the clue.
