Map data refers to the information used to create maps, which visually represent geographic areas. This data includes various elements such as terrain features, roads, landmarks, and boundaries. It can be collected through methods like satellite imagery, aerial photography, and ground surveys, ensuring accurate representations of locations. In addition to physical features, map data often includes demographic information, such as population density and land use. This data is essential for urban planning, navigation, and environmental studies. Technologies like Geographic Information Systems (GIS) help analyze and visualize map data, making it easier to understand spatial relationships and patterns.
