Abstract
The vector data model is used for representation of geographic phenomena as geometric objects composed of points, lines and areas. Lines are used for roads, railroads, streams, or utility networks, while areas can represent soil types, land use categories, lakes, or zoning in urban areas. Vector data are stored using their coordinates. In GRASS, the vector data model includes the description of topology.
