识别要添加至 terrain 的要素。 每个要素必须位于 terrain 所在的要素数据集中,并且其角色通过以下属性定义:
值表列:
Input Features—Name of the feature class being added to the terrain.
Height Field—Field containing the feature's height information.
Type—The way the input future contributes to the terrain surface.
Mass_Points—Points that are used for triangulation.
Hard_Line—Linear features that represent sharp discontinuities in elevation.
Soft_Line—Linear features that represent a gradual discontinuity in elevation.
Hard_Clip—Polygon feature that defines the interpolation zone with sharp discontinuities at the edges.
Soft_Clip—Polygon feature that defines the interpolation zone with gradual discontinuities at the edges.
Hard_Erase—Polygon feature that defines the area to be treated as having no data. The hard designation indicates the boundary of the polygon represents a sharp discontinuity.
Soft_Erase—Polygon feature that defines the area to be treated as having no data. The soft designation indicates the boundary of the polygon represents a gradual discontinuity.
Hard_Replace—Polygon feature that defines a constant z-value for all mass points within the boundary. The hard designation indicates the boundary of the polygon represents a sharp discontinuity.
Soft_Replace—Polygon feature that defines a constant z-value for all mass points within the boundary. The soft designation indicates the boundary of the polygon represents a gradual discontinuity.
Hardvalue_Fill—Polygon feature that defines a constant z-value within its boundary. The hard designation indicates the boundary of the polygon represents a sharp discontinuity.
Softvalue_Fill—Polygon feature that defines a constant z-value within its boundary. The soft designation indicates the boundary of the polygon represents a gradual discontinuity.
Group—Defines the group of each contributing feature.
Min Resolution—The lowest resolution that the surface feature will be enforced.
Max Resolution—The highest resolution that the surface feature will be enforced.
Overview—Indicates whether the feature is enforced at the coarsest representation of the terrain dataset.
Embed—Checking this option indicates the source features will be copied to a hidden feature class that will be referenced by and only available to the terrain.
Embed Name—Name of the embedded feature class.
Embed Fields—Specifies Blob field attributes to be retained in the embedded feature class.
Anchor—Specifies whether the point feature class will be anchored through all terrain pyramid levels.

代码示例
AddFeatureClassToTerrain 示例 1(Python 窗口)
下面的示例演示了如何在 Python 窗口中使用此工具:
arcpy.env.workspace = "C:/data"
terrain_data = ["terrain.gdb/terrainFDS/points2", "SHAPE", "masspoints", 2, 0,
10, "true", "false", "points_embed", "<None>", "false"]
arcpy.ddd.AddFeatureClassToTerrain("test.gdb/featuredataset/terrain", terrain_data)
AddFeatureClassToTerrain 示例 2(独立脚本)
下面的示例演示了如何在独立 Python 脚本中使用此工具:
"""****************************************************************************
Name: Create Terrain from TIN
Description: This script demonstrates how to create a terrain dataset using
features extracted from a TIN. It is particularly useful in
situations where the source data used in the TIN is not available,
and the amount of data stored in the TIN proves to be too large
for the TIN. The terrain's scalability will allow improved
display performance and faster analysis. The script is designed
to work as a script tool with 5 input arguments.
