• Abstract:
  The MS Extended Vector Product (MSEVP) prototype being developed is an extended vector product format-based product containing a continuous surface representation and a consistent view of elevation across the thematic coverages contained within a database. A continuous surface representation is provided in the MSEVP prototype as a Triangulated Irregular Network (TIN) and stored in the MSEVP elevation coverage. This report also examines how a TIN representation of the transportation network is constructed from a two-dimensional linear representation. Each linear road is widened to provide a more realistic representation of its real work counterpart and then overlaid over the elevation TIN to ensure that the road adheres to the surface characterized by the elevation coverage. This overlay process ensures that a consistent view of elevation wille xist across coverages.
