Agregar clase de entidad al terreno (Herramientas de 3D Analyst)

Resumen

Agrega una o más clases de entidades a un dataset de terreno.

Uso

Las entidades de entrada deben residir en el mismo dataset de entidades que el dataset de terreno.
El dataset de terreno ya debe tener uno o más niveles de pirámide definidos.
Dependiendo del tipo de superficie asociada a las entidades agregadas a un terreno, puede ser necesario reconstruir el dataset de terreno usando Construir terreno. El cuadro de diálogo Propiedades del dataset de terreno en ArcCatalog y el cuadro de diálogo Propiedades de la capa de terreno en ArcMap proporcionan una indicación sobre si es necesario reconstruir el dataset.
Considera activar la opción de vista general para tipos de entidades de línea de corte y superficie de polígonos solo si las entidades contienen geometría simplificada y son visualmente relevantes para la escala de visualización prevista. Por ejemplo, las líneas de corte pueden no ser lo suficientemente visibles como para importar en una visualización general, mientras que un polígono de recorte sería útil. Si la entidad límite está detallada, considere generalizarlo y use la representación más gruesa para la vista general. La versión detallada debería usarse a escalas de visualización más adecuadas para su resolución de detalle.
Para datsets de terreno almacenados en una geodatabase corporativa:
- El terreno objetivo no se puede registrar como versionado.
- La clase de entidad de entrada no puede estar registrada como versionada.

Ejemplo 1 de AddFeatureClassToTerrain (ventana de Python)

El siguiente ejemplo muestra cómo usar esta herramienta en la ventana de Python:

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)

Ejemplo 2 de AddFeatureClassToTerrain (secuencia de comando independiente)

El siguiente ejemplo muestra cómo usar esta herramienta en un script independiente de Python:

"""****************************************************************************
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.
