Method for storing spatial data involving assigning coordinates for each entity.
1) Mathematical object with precise direction and length but without specific location. Vector data is stored as XYZ coordinates that describe points, symbols, lines, areas, and volumes.
2) Method for storing spatial data involving assigning coordinates for each entity; an X,Y,Z for a point, a pair of such points for a line, a series of such lines for a polygon, the method is very useful for modeling discrete physical features.
3) Quantity, such as velocity, completely specified by a magnitude and a direction.
