Propiedades FeatureClass

Resumen

La función Describir devuelve las siguientes propiedades para las Clases de entidad. Las Propiedades de la tabla y las Propiedades del dataset también son compatibles.

Una Clase de entidad devuelve un tipo de datos de "FeatureClass".

Propiedades

Propiedad	Explicación	Tipo de datos
featureType (Sólo lectura)	The feature type of the feature class. Simple —Polygons, polylines, and points representing objects or places that have area such as water bodies; linear objects such as rivers; and localized positions, such as houses or sample sites. SimpleJunction —Simple junction feature in a geometric network representing point objects, such as a fuse, service point, or telephone pole. SimpleEdge —Simple edge feature in a geometric network representing polyline objects, such as primary or secondary overheads. ComplexEdge —Complex edge feature in a geometric network representing polyline objects, such as primary overheads, which have midspan connectivity. Network resources flow through complex edge without interruption by midspan connectivity. Annotation —Place or object names or identifiers, such as street names, hydrant ID numbers, land values, or elevation. CoverageAnnotation —Place or object names or identifiers, such as street names, hydrant ID numbers, land values, or elevation. Not supported in geodatabases; only supported in coverage datasets. Dimension —Measurements, such as distances, lengths, widths, and depths. RasterCatalogItem —A raster dataset in a raster catalog that has information, such as footprints, names, metadata, and any other user-defined attributes.	String
hasM (Sólo lectura)	Indicates if the geometry is m-value enabled.	Boolean
hasZ (Sólo lectura)	Indicates if the geometry is z-value enabled.	Boolean
hasSpatialIndex (Sólo lectura)	Indicates if the feature class has a spatial index.	Boolean
shapeFieldName (Sólo lectura)	The name of the Shape field.	String
shapeType (Sólo lectura)	The geometry shape type. Polygon Polyline Point MultiPoint MultiPatch	String

FeatureClass properties example (stand-alone script)

The following stand-alone script displays some feature class properties.

import arcpy

# Create a Describe object from the feature class
#
desc = arcpy.Describe("C:/data/arch.dgn/Point")

# Print some feature class properties
#
print "Feature Type:  " + desc.featureType
print "Shape Type :   " + desc.shapeType
print "Spatial Index: " + str(desc.hasSpatialIndex)
