In GIS, Vector data represents geographic features as points, lines, and polygons. Each vector feature is defined by its coordinates and can store data attributes describing the feature. Vector data is particularly useful for applications that require precise geographic positioning and detailed attribute management, such as mapping city infrastructure, cadastral surveys, and thematic mapping. Unlike raster data, which captures data in a grid format, vector data allows for more straightforward querying and efficient spatial analysis of discrete features across various scales.
