Threshold Trade Areas

Доступно с лицензией Business Analyst.

Сводка

Creates rings around your stores. The radii of the rings are determined by expanding from the store location until they meet your criteria.

Threshold trade areas example

Использование

  • The spatial reference of the output feature class will be the same as the store layer.

  • The store layer input feature class must be point features.

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

  • Valid numeric units must be used when defining radii values. Negative values cannot be used for threshold radii.

  • Selecting all sites to use will create rings for each point feature in the ring centers (stores) input feature class.

  • In ArcMap, trade areas will only be created for features that are within the active study area or analysis extent.

  • The threshold layer must be a point or polygon feature class and be set up as a Business Analyst Dataset (BDS) layer. In most cases, you should select the block group or block points layer.

ПараметрОбъяснениеТип данных
InputFeatureLayer

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

Feature Layer
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.

  • All —Creates rings for all points.
  • Single —Creates rings for a single point.
  • Selected —Creates rings for all selected points in ArcMap.
String
ThresholdFeatureLayer

The input feature class containing the threshold data that will determine the radii.

Feature Layer
ThresholdPopulationField

The threshold value field contained in the threshold layer.

Field
MeasureUnits
[MeasureUnits,...]
(Дополнительный)

The units used with the distance values. By default, the units defined in the Business Analyst preferences will be selected.

  • Minutes
  • Feet
  • Kilometers
  • Meters
  • Miles
  • Nautical Miles
  • Yards
String
RingsCollection
RingsCollection;RingsCollection...

The number of radii and the threshold values for each ring.

Double
OutputFeatureClass

The feature class that will contain the ring features.

Feature Class
ByID_Or_ByName
(Дополнительный)

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
(Дополнительный)

ID or name of store to be used as the single point.

String
UsedAlghoritm
(Дополнительный)

The technique that will be used the generate the threshold trade areas.

  • Use Standard Threshold Rings —Your threshold trade areas will be generated based on static rings.
  • Use Threshold Drive Times —Your threshold trade areas will be generated based on drive-time trade areas.
String
Donut
(Дополнительный)

Defines whether to create nonoverlapping concentric rings or donut bands.

  • TRUE —Creates output polygons that are donut rings. For example, if three radii (1, 2, and 3 miles) are entered, three output bands would be created with 0–1-, 1–3-, and 3–5-mile rings. This is the default.
  • FALSE —Creates concentric rings.
Boolean
BarrierFeatureClasses
[BarrierFeatureClasses,...]
(Дополнительный)

You can place point, line, or polygon barriers when using drive time or drive distance algorithms to calculate distances.

Feature Layer
UseOnlineData
(Дополнительный)

Select to access online Business Analyst data to use in the analysis.

  • True —Allows you to acess online Business Analyst data.
  • False —You will only have access to locally loaded Business Analyst data. This is the default.
Boolean
