Mass Update By Tracing (Production Mapping)
概要
This tool updates feature attributes in a geometric network. The tool can update any feature class that participates in the geometric network and is connected to Input Source Features. A trace task determines connectivity. Any feature connected to, upstream, or downstream of a feature in Input Source Features is updated.
使用法
-
This tool requires an edit session. The tool automatically starts one if necessary.
-
The Input Target Features parameter contains feature classes that participate in the geometric network.
-
The trace performed on the network varies based on the disabled status of each feature class in the network.
-
Set the flow direction on the geometric network before using this tool with the Trace Upstream and Trace Downstream trace tasks.
構文
パラメータ | 説明 | データ タイプ |
in_geometric_network |
The geometric network that contains the features you want to update. | Geometric Network |
in_source_features |
The feature layer that contains the features on which the trace is based. | Feature Layer |
in_source_field |
The field in the source layer that is used to update values in the target layers. | Field |
in_target_features [[Layer, {Edit}, {Disable}, {Field}].,...] |
Lists the feature classes to update in the geometric network. You must include three different properties for each feature class to update:
| Value Table |
in_trace_task |
The tracing task to use to update the target features.
| String |
in_additional_source_expression (オプション) |
A Structured Query Language (SQL) expression that defines which source features to use to update the target features. | SQL Expression |
in_use_barriers (オプション) |
Indicates whether barriers in the geometric network are used in the update process.
| Boolean |
