Original Ground
Original Ground files can be produced automatically by a machine that is equipped with CAESultra.
Illustration 3 g00989531
If the automatic method is not used, then the Original Ground file is created from a series of ground survey points (4). The points are obtained using either a site design software package or else a surveyor software package.

Original ground survey pointsThe original ground points will typically be used to create a Triangulated Irregular Network (TIN) (5) of the area.
Illustration 5 g01191573
Triangulated Irregular Network (TIN)The CAESultra system uses a grid system (6) in order to represent both the original ground and the current ground. A combination of the overall area, the size of the machine, and the resolution that is required for the Surface Model, all affect the spacing of the established grid.
Illustration 6 g01191606
(6) Grid arrangement (7) Grid cell centersThe TIN uses a set of Cartesian coordinates to define the center points, (x) and (y), and the elevations (z) of the cells within the grid.

Grid arrangement with cell center elevations (8) CAESultra then uses these coordinates to create an "Internal surface" grid cell model (9) that represents the original ground. This model will be used for operations and calculations.

The current ground (2) is the surface that is continuously updated as the machine traverses the area. Typically, the initial Current ground and the Original ground are identical. Current ground files can be produced automatically by a machine that is equipped with CAESultra.

Illustration 11 depicts the process for updating the terrain model. The actual topography of the terrain is used as a starting point for the model. As the machine traverses the terrain, an updated terrain model is produced. The terrain elevations cannot be updated until the machine traverses the area. Once the dozing operations are completed, the terrain model can be accurately updated.

The design can be created by using a "site design" software package.

Elevation design created with software packageCAESultra requires Elevation Design files that are in the TIN format. ReferenceRefer to Systems Operation, RENR9966, "METSmanager User Guide" for supported formats.
