Generate Threshold Rings (Business Analyst)

Доступно с лицензией Business Analyst.

Краткая информация

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.

Input Features	The input point feature layer.	Feature Layer
Output 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	The size of the output rings. The rings will expand until they contain the threshold value of the selected variable.	Double
Distance 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
