Generate Threshold Rings (Business Analyst)

Доступно с лицензией Business Analyst.

Сводка

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

Использование

• 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.

Синтаксис

arcpy.ba.GenerateThresholdRingTradeArea(in_features, out_feature_class, threshold_variable, threshold_values, {units}, {id_field}, {input_method}, {expression})

Parameter	Объяснение	Тип данных
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 (Дополнительный)	The distance units to be used with the threshold values.	String
id_field (Дополнительный)	An ID that uniquely identifies each input point and is included in the output as an attribute.	Field
input_method (Дополнительный)	Specifies the type of value that is to be used for each drive time. VALUES —Uses a constant value (all trade areas will be the same size). This is the default. EXPRESSION —The values from a field or an expression (trade areas can be a different size).	String
expression (Дополнительный)	A fields-based expression to calculate the radii.	SQL Expression
