Represented of Geometric Information Various geometric constructs can be represented in a database in a normalized fashion. Represent a line segment by the coordinates of its endpoints. Approximate a curve by partitioning it into a sequence of segments Create a list of vertices in order,or Represent each segment as a separate tuple that also carries with it the identifier of the curve(2D features such as roads). Closed polygons List of vertices in order,starting vertex is the same as the ending vertex.or Represent boundary edges as separate tuples,with each containing identifier of the polygon,or Use triangulation-divide polygon into triangles Note the polygon identifier with each of its triangles.
