Résumé

Creates a new feature class of ring trade area features. The radii are determined by a field in the ring center (store) layer.

Syntaxe

DataDrivenRings_ba (InputFeatureLayer, IDField, All_Or_Single_Or_Selected, RadiusFieldName, ValuePerUnit, {MeasureUnits}, OutputFeatureClass, {ByID_Or_ByName}, {Single_Site}, {RemoveOverlap}, {ExpValue})
ParamètreExplicationType de donnée
InputFeatureLayer

The input feature class containing center points for the rings. In most cases, this will be a Business Analyst store layer.

Feature Class
IDField

Unique ID field in the ring center (store) layer.

Field
All_Or_Single_Or_Selected

Creates rings for points in the input feature layer.

  • ALLCreates rings for all points. This is the default
  • SINGLECreates rings for a single point.
  • SELECTEDCreates rings for all selected points in ArcMap.
String
RadiusFieldName

Field used to determine radii of the rings.

Field
ValuePerUnit

Value entered proportional to one measured unit. For example, $50,000 in sales is equal to 1 mile.

Double
MeasureUnits
(Facultatif)

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
  • Nautical Miles
  • Yards
String
OutputFeatureClass

The feature class that will contain the ring features.

Feature Class
ByID_Or_ByName
(Facultatif)

Field used to select a single point.

  • IDSelects a single point using the store ID field.
  • NAMESelects a single point using the store name field.
String
Single_Site
(Facultatif)

ID or name of store used as the single point.

String
RemoveOverlap
(Facultatif)

Creates overlapping concentric rings or removes overlap.

  • trueUses Thiessen polygons to remove overlap between output ring polygons.
  • false Output ring features are created with overlap. This is the default.
Boolean
ExpValue
(Facultatif)

An exponent value to determine the size of the data-driven rings. This exponent is the same type of exponent used in the Huff Modeling.

Double
