The term MAP CLOSE-UP is composed of two words: MAP and INSET. MAP stands for a diagrammatic representation of an area, usually drawn to scale, showing physical features, cities, roads, etc. An INSET is a small MAP or diagram inserted within the borders of a larger one, used to show in more detail a particular area of the main MAP. Therefore, MAP CLOSE-UP refers to a detailed MAP of a specific area, usually shown as an INSET within a larger MAP.
