A Shapefile is a popular geospatial vector data format used in geographic information system (GIS) software. It stores the geometric location and attribute information of geographic features, such as points, lines, and polygons. Each shapefile consists of at least three main files: the .shp file for geometry, the .shx file for shape index, and the .dbf file for attribute data. Shapefiles are widely used for mapping and spatial analysis, allowing users to visualize and analyze geographic data easily. They can represent various features, including roads, rivers, and administrative boundaries, making them essential for urban planning, environmental studies, and resource management.
