Vector GIS
Abstract
The Vector GIS model is based on vectors (as opposed to spaceoccupancy raster structures). Its fundamental primitive is a point. Objects are created by connecting points with straight lines. Some systems allow points to be connected using arcs of circles. Areas are defined by sets of lines. The term polygon is synonymous with area in
vector databases because of the use of straight line connections between points. This presentation discusses various uses of Vector GIS, including editing, storage, edge-matching, and the creation of arcs.
