Desire Lines (Business Analyst)

概要

Creates a series of lines from each customer to an associated store location. These lines are often called spider diagrams.

使用法

• In most cases, the input Store Layer will be a Business Analyst store layer.

• The Store Layer must be a point feature class.

• In ArcMap, desire lines will only be drawn to customer points that are within the active study area or analysis extent. If you want to draw desire lines to all customer points, make sure that all customers are within the analysis extent.

• Creating desire lines with drive time and drive distance will take significantly longer than using the straight-line (Euclidean) distance method.

• Check the Add Distance to Customer Layer checkbox if you want to append the distance from the customer point to the associated store location for each customer record.

• Only customers in the active extent or study area will be used in this analysis.

• Use the Assign By Closest Stores Location or Assign By Trade Area tools in the Customer Setup toolset if your customers are not assigned to a store location.

パラメータ	説明	データ タイプ
InputFeatureLayer	The input feature layer containing the center points for the desire lines. Desire lines are drawn from these features.	Feature Layer
IDField	Field used to uniquely identify each store.	Field
All_Or_Single_Or_Selected	Runs a desire line analysis on one or more stores. ALL —Runs analysis on all stores. This is the default. SINGLE —Runs analysis on a single store.	String
CustomerLayer	Contains the customer points for the desire lines. Desire lines are drawn from the store to these features.	Feature Layer
LinkField	The store ID field in the customer layer that assigns each customer to a store.	Field
DistanceCalculateMethod	The method used to derive length of each desire line. DRIVE_TIME —Driving time measured in units of time. DRIVE_DISTANCE —Driving distance measured in units of distance. STRAIGHT_LINE_DISTANCE —Straight-line distance. This is the default.	String
MeasureUnitsForDistanceField	The units used with the distance values. Decimal Degrees — Feet — Kilometers — Meters — Miles —This is the default. Nautical Miles — Yards —	String
OutputFeatureClass	The feature class that will contain the desire lines.	Feature Class
ByID_Or_ByName （オプション）	Field used to select a single point. ID —Selects a single point using the store ID field. Name —Selects a single point using the store name field.	String
Single_Site （オプション）	ID or name of store that is to be used as the single point.	String
UseSelectedFeatures （オプション）	Uses only selected features to generate the desire lines. True —Generates desire lines on selected features. False —Generates desire lines on all features.	Boolean
ExcludeOutlyingCustomers （オプション）	Allows you to set a cutoff distance to remove outlying points from the analysis. True —Excludes outlying customers. False —Includes outlying customers.	Boolean
CutOffDistance （オプション）	The threshold to exclude outlying customers from the analysis.	Double
MeasureUnits （オプション）	The units used with the distance values. By default, the units defined in the Business Analyst preferences will be selected. Decimal Degrees — Feet — Kilometers — Meters — Miles —This is the default. Nautical Miles — Yards —	String
AddDistanceToBusiness （オプション）	Adds a new field that will contain the distance calculated to each store for each customer record. True —Adds a distance field to the customer layer. False —Does not add a distance field to the customer layer. This is the default.	Boolean
WayToDefineDistanceField （オプション）	Uses an existing distance field in the customer layer to store the length of each desire line. CREATE_NEW —Creates a new attribute field for distance. This is the default. USE_EXISTING —Uses an existing attribute field for distance.	Boolean
DesireLinesDistanceField （オプション）	The field that will contain the distance calculated in the analysis.	String
NameField （オプション）	This field contains the store name which is typically in a string format.	Field
BarrierFeatureClasses [BarrierFeatureClasses,...] （オプション）	Allows a user to place point, line, or polygon barriers when using drive time or drive distance algorithms to calculate distances.	Feature Layer
