Static rings example

使用方法

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

  • Valid numeric distances must be used when defining radii values. Negative distances cannot be used for ring radii.

  • Selecting ALL in the Sites To Use parameter will create rings for each point feature in the store layer input feature class.

  • The Remove Overlap parameter uses Thiessen polygons to remove overlap between output ring polygons.

  • Donut rings create output polygons that are bands. For example, if three radii are entered with values of 1, 2, and 3 miles, three output bands would be created with 0–1-, 1–3-, and 3–5-mile rings.

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

语法

arcpy.ba.StaticRings(InputFeatureLayer, IDField, All_Or_Single_Or_Selected, RingsCollection, {MeasureUnits}, OutputFeatureClass, {ByID_Or_ByName}, {Single_Site}, {RemoveOverlap}, {Donut})
参数说明数据类型
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 —Rings are created for all points.
  • SINGLE —Rings are created for a single point.
  • SELECTED —Rings are created for all selected points in ArcMap.
String
RingsCollection
[RingsCollection,...]

The distances, in ascending size, used to create rings around the input features.

Double
MeasureUnits
[MeasureUnits,...]
（可选）

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
（可选）

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
（可选）

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

String
RemoveOverlap
（可选）

Creates overlapping concentric rings or removes overlap.

  • TRUE —Uses Thiessen polygons to remove overlap between output ring polygons.
  • FALSE —Output ring features are created with overlap. This is the default.
Boolean
Donut
（可选）

Creates 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
