Dissolve By Attribute Range (Business Analyst)

概要

Aggregates and dissolves features based on specified attributes.

使用法

• 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.

構文

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

パラメータ	説明	データ タイプ
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.	Double
OutputFeatureClass	The feature class that will contain the dissolved attributes.	Feature Class
SelectedFeaturesOnly （オプション）	Uses selected features to dissolve by attribute. True —Dissolves selected features. False —Dissolves all features.	Boolean
Donut （オプション）	Creates nonoverlapping concentric rings, or donut bands. True —Creates output polygons that are donut rings. For example, if three radii (1, 2, and 3 miles) are entered, three output bands would be created with 0–1-, 1–3-, and 3–5-mile rings. False —Creates concentric rings.	Boolean
