描述
Creates rings around point locations.

使用方法
Valid numeric distances must be used when defining distance values. Negative distances cannot be used for rings.
The Remove Overlap parameter uses Thiessen polygons to remove overlap between output ring polygons.
语法
GenerateTradeAreaRings(in_features, out_feature_class, radii, {units}, {id_field}, {remove_overlap}, {dissolve_option})
参数 | 说明 | 数据类型 |
in_features | The input features containing the center points for the rings. | Feature Layer |
out_feature_class | The feature class that will contain the output ring features. | Feature Class |
radii [radii,...] | The distances, in ascending size, used to create rings around the input features. | Double |
units (可选) | The linear unit to be used with the distance values. | String |
id_field (可选) | A unique ID field in the ring center layer. | Field |
remove_overlap (可选) | Creates overlapping concentric rings or removes overlap.
| Boolean |
dissolve_option (可选) | Specifies whether overlapping or nonoverlapping service areas for a single location will be used when multiple distances are specified.
| String |
代码示例
The following Python window script demonstrates how to use the GenerateTradeAreaRings tool.
import arcpy
arcpy.ba.GenerateTradeAreaRings("sales_locations.shp",
r"sales_locations_GenerateTrad.shp", [1, 3, 5],
"MILES", "ID", "KEEP_OVERLAP")
