Summary

• SEDRIS allows terrain data to be represented in several different ways:

  • Raster, as Image objects in an Image Library
  • Gridded, as Property Grid objects in a Data Table Library and/or in the geometry hierarchy within the Environment Root or a Model
  • Vector, as Feature and Feature Topology objects hierarchically organized within the Environment Root or a Model
  • Polygonal, as Geometry and optional Geometry Topology objects hierarchically organized within the Environment Root or a Model

• SEDRIS provides many mechanisms for hierarchically organizing Feature and Geometry objects that represent terrain:

  • Spatial, Level of Detail, Classification, State, Time, etc., etc., etc.

• SEDRIS allows multiple representations of the same terrain to be associated:

  • Feature <-> Feature
  • Feature <-> Geometry Hierarchy
  • Geometry Hierarchy <-> Geometry Hierarchy
  • Feature <-> Property Grid
