FeatureClass properties (arcpy)

Récapitulatif

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".

Propriétés

PropriétéExplicationType de données
featureType
(Lecture seule)

The feature type of the feature class.

  • SimplePolygons, 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.
  • SimpleJunctionSimple junction feature in a geometric network representing point objects, such as a fuse, service point, or telephone pole.
  • SimpleEdgeSimple edge feature in a geometric network representing polyline objects, such as primary or secondary overheads.
  • ComplexEdgeComplex 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.
  • AnnotationPlace or object names or identifiers, such as street names, hydrant ID numbers, land values, or elevation.
  • CoverageAnnotationPlace 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.
  • DimensionMeasurements, such as distances, lengths, widths, and depths.
  • RasterCatalogItemA raster dataset in a raster catalog that has information, such as footprints, names, metadata, and any other user-defined attributes.
String
hasM
(Lecture seule)

Indicates if the geometry is m-value enabled.

Boolean
hasZ
(Lecture seule)

Indicates if the geometry is z-value enabled.

Boolean
hasSpatialIndex
(Lecture seule)

Indicates if the feature class has a spatial index.

Boolean
shapeFieldName
(Lecture seule)

The name of the Shape field.

String
shapeType
(Lecture seule)

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)
