Dataset properties

サマリー

The Describe function returns the following properties for datasets.

Dataset properties are available in many types of Describe objects.

String
DSID
(読み取り専用)

The ID of the dataset.

Integer
extent
(読み取り専用)

The Extent object.

注意:

extent is available for spatial datasets only.

Extent
isArchived
(読み取り専用)

Indicates whether the dataset has been archived. isArchived is only supported for an enterprise geodatabase.

Boolean
isVersioned
(読み取り専用)

Indicates whether the dataset is versioned.

Boolean
MExtent
(読み取り専用)

A space-delimited string (MMin, MMax).

注意:

MExtent is available for spatial datasets only.

String
spatialReference
(読み取り専用)

Returns the SpatialReference object for the dataset.

注意:

spatialReference is available for spatial datasets only.

SpatialReference
workspace
(読み取り専用)

Returns a Describe object with the properties of the input dataset's workspace.

See Workspace properties for specific workspace-related Describe details.

注意:

Use this property to determine workspace properties for many data types including: layers, and feature classes in a geodatabase that may or may not be in a feature dataset.

Describe
ZExtent
(読み取り専用)

A space-delimited string (ZMin, ZMax).

注意:

ZExtent is available for spatial datasets only.

String

Dataset properties example

The following stand-alone script displays dataset properties for a shapefile.

import arcpy

# Create a Describe object from the shapefile
#
desc = arcpy.Describe("C:/temp/xy.shp")

# Print dataset properties
#
print(("Dataset Type: {0}".format(desc.datasetType)))
print(("Extent:\n  XMin: {0}, XMax: {1}, YMin: {2}, YMax: {3}".format(
    desc.extent.XMin, desc.extent.XMax, desc.extent.YMin, desc.extent.YMax)))
print(("MExtent: {0}".format(desc.MExtent)))
print(("ZExtent: {0}".format(desc.ZExtent)))

print(("Spatial reference name: {0}:".format(desc.spatialReference.name)))
