Generate Threshold Rings (Business Analyst)

获得 Business Analyst 许可后可用。

描述

Creates a feature class of ring trade areas that expand around point features until the threshold value is reached.

使用方法

• The size of the output rings is determined by Threshold Values entered for a selected Threshold Variable from the active Business Analyst dataset.

• Multiple threshold rings can be created around each input by typing individual values into separate threshold value text boxes.

• The ID Field parameter value uniquely identifies the point location around which threshold rings are created.

语法

GenerateThresholdRingTradeArea(in_features, out_feature_class, threshold_variable, threshold_values, {units}, {id_field})

参数	说明	数据类型
in_features	The input point feature layer.	Feature Layer
out_feature_class	The output feature class.	Feature Class
threshold_variable	The selected Business Analyst dataset variable to which the threshold value will be applied.	String
threshold_values [threshold_values,...]	The size of the output rings. The rings will expand until they contain the threshold value of the selected variable.	Double
units （可选）	The distance units to be used with the threshold values.	String
id_field （可选）	An ID that uniquely identifies each input point and is included in the output as an attribute.	Field

GenerateThresholdRingTradeArea example (Python window)

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

import arcpy
arcpy.ba.GenerateThresholdRingTradeArea("SF_Custs",
                                        r"C:\Project1.gdb\SF_Custs_GenerateThresholdRingTradeArea",
                                        "populationtotals.totpop_cy",
                                        [50000, 100000], "MILES", "STORE_ID")
