FeatureClass properties

サマリー

The Describe function returns the following properties for Feature Classes. Table Properties and Dataset Properties are also supported. Editor Tracking Properties are supported if editor tracking has been enabled for this feature class.

A Feature Class returns a dataType of "FeatureClass".

プロパティ

プロパティ	説明	データ タイプ
featureType (読み取り専用)	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 edges 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 (読み取り専用)	Indicates whether the geometry is m-value enabled.	Boolean
hasZ (読み取り専用)	Indicates whether the geometry is z-value enabled.	Boolean
hasSpatialIndex (読み取り専用)	Indicates whether the feature class has a spatial index.	Boolean
shapeFieldName (読み取り専用)	The name of the geometry field.	String
shapeType (読み取り専用)	The geometry shape type. Polygon Polyline Point Multipoint MultiPatch	String
splitModel (読み取り専用)	The split model that is set for the feature class. DeleteInsertInsert UpdateInsert	String

コードのサンプル

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))
