Add Feature Class to Terrain
Adds one or more feature classes to a terrain dataset.
1. Input Terrain
The terrain to which feature classes will be added. The terrain dataset must already have one or more pyramid levels created.
2. Input Feature Class
Identifies features being added to the terrain. Each feature must reside in the same feature dataset as the terrain and have its role defined through the following properties:
·
Input Features—Name of the feature class being added to the terrain.
·
Height Field—Field containing the feature's height information.
Any numeric field can be specified, and z-enabled features can also choose the
geometry field. If the <none> option is chosen, z-values are interpolated
from the surface.
·
Type—Surface feature type that defines how the features
contributes to the terrain. Mass points denote features that contribute
z-measurements; breaklines denote linear features with known z-measurements,
and several polygon types. Breaklines and polygon-based feature types also have
hard and soft qualifiers that define the interpolation behavior around the
feature's edges when exporting to raster. Soft features exhibit gradual changes
in slope, whereas hard features represent sharp discontinuities.
·
Group—Defines the group of each contributing feature.
Unspecification of breaklines and polygon surface features representing the
same geographic features at different levels of detail are intended for display
at certain scale ranges. Data representing the same geographic features at
different levels of detail can be grouped by assigning the same numeric value.
For example, assigning two boundary features with a high and low level of
detail to the same group would ensure there is no overlap in their associated
display scale range.
·
Min/Max Resolution—Defines the range of pyramid resolutions at
which the feature is enforced in the terrain. Mass points must use the smallest
and largest range of values.
·
Overview—Indicates whether the feature is enforced at the coarsest
representation of the terrain dataset. To maximize display performance, make
sure that feature classes represented in the overview contain simplified
geometry. Only valid for feature types other than mass points.
·
Embed—Setting this option to TRUE indicates the source features
will be copied to a hidden feature class that will be referenced by and only
available to the terrain. Embedded features will not be directly viewable, as
they can only be accessed through terrain tools. Only valid for multipoint
features.
·
Embed Name—Name of the embedded feature class. Only applies if the
feature is being embedded.
·
Embed Fields—Specifies BLOB field attributes to be retained in the
embedded feature class. These attributes can be used to symbolize the terrain.
LAS attribution can be stored in BLOB fields of multipoint features through the
LAS To Multipoint tool.
· Anchor—Specifies whether the point feature class will be anchored through all terrain pyramid levels. Anchor points are never filtered or thinned away to ensure they persist in the terrain surface. This option only applies to single-point feature classes.

Add Terrain Pyramid Level
Adds one or more pyramid
levels to an existing terrain dataset.
1. Input Terrain
The terrain dataset to
process.
2. Pyramid Levels Definition
The z-tolerance or window size and its associated reference scale for each pyramid level being added to the terrain. Each pyramid level is entered as a space-delimited pair of the pyramid level resolution and reference scale (for example, "20 24000" for a window size of 20 and reference scale of 1:24000, or "1.5 10000" for a z-tolerance of 1.5 and reference scale of 1:10000). The pyramid level resolution can be provided as a floating-point value, while the reference scale must be entered as a whole number.
The z-tolerance value represents the maximum deviation that can occur from the elevation of the terrain at full resolution, whereas the window size value defines the area of the terrain tile used in thinning elevation points by selecting one or two points from the area based on the window size method defined during the creation of the terrain. The reference scale represents the largest map scale at which the pyramid level is enforced. When the terrain is displayed at a scale larger than this value, the next highest pyramid level is displayed.
3. Pyramid Type (optional)
The pyramid type used by the terrain dataset. This parameter is not used in ArcGIS 9.3 and beyond, as its purpose is to ensure backward-compatibility with scripts and models written using ArcGIS 9.2.
