DefinitionA shapefile (シェープファイル) is a geographic data file format that stores the shapes of map features (points, lines, and polygons) together with their attributes.
ExplanationOne dataset is made up of several files with different extensions that work as a set. For instance, a bus stop is recorded as a point, a road as a line, and a town block as a polygon, with attributes such as name and area attached in table form. Most geographic information system software can read and write the format, so it is widely used to exchange map data.
AnalogyIt is like putting a stack of shapes drawn on a map and a stack of note cards describing each shape into one envelope.
Memory hookAs the word shape suggests, it is a file that records shapes.
