The Terrain Modeling Solution is a set of tools to generate slope, elevation and aspect terrain models with user-defined classes. The output can be generalized and smoothed. Output options include shape files for rendering or line files with centroids for colour theming using the Poly-Theming Solution or subsequent GIS analysis. It includes specialized utilities and the following modules:

SEA 3D
SEA 3D generates slope, elevation and aspect class polygons from a MAPS 3D binary TIN surface. Optional outputs include 3D gridded shapes or polygon boundaries and centroids.   The Classes can be represented by either Text or Textnodes.  

SEA SMOOTH 3D
SEA SMOOTH 3D is used to "smooth" polygon boundaries from SEA 3D to improve their cartographic appearance.

SEA NEAT 3D
SEA NEAT 3D facilitates correct placement of polygon centroids within the map sheet boundary.

All three modules within the Terrain Modeling Solution can be executed from within a MAPS 3D script for batch processing of multiple files.

For the additional utility to accompany the Terrain Modeling Solution, we suggest: CENTROID 3D, MAP SURROUND 3D or MOEP 3D.
