Input Feature Dataset
The feature dataset that will contain the terrain dataset.
The name of the terrain dataset.
Average Point Spacing
The average horizontal distance between the data points that will be used in modeling the terrain. Sensor based measurements—such as photogrammetric, lidar, and sonar surveys—typically have a known spacing that should be used. Use the horizontal units of the feature dataset's coordinate system for the spacing.
Maximum Overview Size
The terrain overview is similar to the image thumbnail concept. It is the coarsest representation of the terrain dataset, and the maximum size represents the upper limit of the number of measurement points that can be sampled to create the overview.
The configuration keyword that will be used to optimize the terrain's storage in an enterprise database.
Specifies the point thinning method that will be used to construct the terrain pyramids.
Window Size Method
Specifies how points in the area defined by the window size will be selected. This parameter is only applicable when Window Size is specified for the Pyramid Type parameter.
Secondary Thinning Method
Specifies additional thinning that will be performed to reduce the number of points used over flat areas when window size pyramids are used. An area is considered flat if the heights of points in that area are within the Secondary Thinning Threshold parameter value. Its effect is more evident at higher-resolution pyramid levels, since smaller areas are more likely to be flat than larger areas.
Secondary Thinning Threshold
The vertical threshold that will be used to activate secondary thinning when the Pyramid Type parameter is set to Window Size. Set the value equal to or larger than the vertical accuracy of the data.
Specifies whether breakline features will be incorporated into the terrain surface by densifying their segments to conform to Delaunay triangulation rules for constructing a TIN surface.
Delaunay triangulation will densify breakline features to accommodate the points surrounding them in a manner that avoids the creation of long, thin triangles that typically yield undesirable results when analyzing a TIN-based surface. Additionally, natural neighbor interpolation and Thiessen (Voronoi) polygon generation can only be performed on conforming Delaunay triangulations.
A constrained Delaunay triangulation will avoid densifying breakline features, incorporating breakline segments as edges into the TIN surface. Consider this option when you need to explicitly define certain edges that are guaranteed not to be modified (that is, split into multiple edges) by the triangulator.
