Generate Trade Area Rings (Business Analyst)

Available with Business Analyst license.

Summary

Creates rings around point locations.

Illustration

Usage

• Valid numeric distances must be used when defining distance values. Negative distances cannot be used for rings.

• The Remove Overlap parameter uses Thiessen polygons to remove overlap between output ring polygons.

Syntax

GenerateTradeAreaRings(in_features, out_feature_class, radii, {units}, {id_field}, {remove_overlap}, {dissolve_option})

Parameter	Explanation	Data Type
in_features	The input features containing the center points for the rings.	Feature Layer
out_feature_class	The feature class that will contain the output ring features.	Feature Class
radii [radii,...]	The distances, in ascending size, used to create rings around the input features.	Double
units (Optional)	The linear unit to be used with the distance values.	String
id_field (Optional)	A unique ID field in the ring center layer.	Field
remove_overlap (Optional)	Creates overlapping concentric rings or removes overlap. REMOVE_OVERLAP —Thiessen polygons are used to remove overlap between output ring polygons. KEEP_OVERLAP —Output ring features are created with overlap. This is the default.	Boolean
dissolve_option (Optional)	Specifies whether overlapping or nonoverlapping service areas for a single location will be used when multiple distances are specified. OVERLAP — Each polygon will include the area reachable from the facility up to the distance value. This is the default. SPLIT — Each polygon will include only the area between consecutive distance values.	String

Code sample

GenerateTradeAreaRings example (Python window)

The following Python window script demonstrates how to use the GenerateTradeAreaRings tool.

import arcpy
arcpy.ba.GenerateTradeAreaRings("sales_locations.shp",
                                r"sales_locations_GenerateTrad.shp", [1, 3, 5],
                                "MILES", "ID", "KEEP_OVERLAP")
