Mit der Business Analyst-Lizenz verfügbar.

Zusammenfassung

Aggregates and dissolves features based on specified attributes.

Learn more about how Dissolve By Attribute Range works

Verwendung

  • The spatial reference of the output feature class will be the same as the layer containing attributes.

  • Current map layers can be used to define input features. When using layers, only the currently selected features are used in the dissolve operation.

  • The dissolved fields are written to the output feature class table.

  • One common use of this tool is to take the output of a thematic map and dissolve the features as a single polygon or feature.

  • You can use this tool to dissolve the output from Huff Models to create probabilistic trade areas based on probability ranges.

Syntax

DissolveByAttributeRange_ba (InputFeatureLayer, IDField, ContoursValues, OutputFeatureClass, {SelectedFeaturesOnly}, {Donut})
ParameterErläuterungDatentyp
InputFeatureLayer

Layer containing the values that will be dissolved.

Feature Layer
IDField

The attribute field containing the values to be dissolved.

Field
ContoursValues
[ContoursValues,...]

The range for each attribute to be dissolved. If using the Python function call, you can enter multiple values separated by semicolons (e.g. "250;500;1000;2000").

Double
OutputFeatureClass

The feature class that will contain the dissolved attributes.

Feature Class
SelectedFeaturesOnly
(optional)

Uses selected features to dissolve by attribute.

  • True —Dissolves selected features.
  • False —Dissolves all features.
Boolean
Donut
(optional)

Creates non-overlapping concentric rings, or donut bands.

  • True —Creates output polygons that are donut rings. For example, if three radii (1, 3, and 5 miles) are entered, three output bands would be created with 0–1, 1–3, and 3–5 mile rings.
  • False —Creates concentric rings.
Boolean
