Vector

Vector Data Types:

In vector data the basic units of spatial information are:

• Point = Location position, no area.
• Line = Length, no width
• Polygon = Area and perimeter
  

Advantages of Vector Structure:

• Capable of handling points, lines, and areas as seperate classes of data.
• Topology can be completely described, including network linkages.
• Great looking graphics ("Looks like a map is supposed to")
• Classification generalization is easy, however, the end map user cannot detect that the data have been homogenized; such processing description must accompany the map.
