Extract Data (Production Mapping)
Zusammenfassung
Extracts input features to a geodatabase. You can optionally filter the input features with a polygon from another layer.
Verwendung
-
Input Datasets can include points, polylines, polygons, and annotation features.
If the input features include a topology, features are extracted from all the layers that participate in the topology. This may be in addition to the layers you have specified in the Input Datasets parameter.
Extracted data will have the same name as Input Datasets.
All data in Input Datasets must originate from the same workspace.
If extracted data originate from a feature dataset, the tool will create a feature dataset of the same name in the target geodatabase.
The target geodatabase must exist before this tool can run.
The Re-use Schema (in_reuse_schema) parameter is enabled for file and personal geodatabases only.
The Filter by Geometry parameter requires one selected feature in the Filter Feature Layer. The tool will return a Filter feature layer selection count not equal to 1 error if there are zero or more than one selected features.
The selected feature in the Filter Feature Layer but be a polygon. If it is not, the tool will return a Filter feature layer must be polygon geometry type error.
To use this tool in a stand-alone script, check out a production mapping foundation license: arcpy.CheckOutExtension("Foundation").
Syntax
| Parameter | Erläuterung | Datentyp |
in_datasets [in_datasets,...] |
The input data to extract into another geodatabase. | Feature Layer |
in_target_gdb |
The workspace into which data will be extracted. | Workspace |
in_reuse_schema (optional) |
Indicates whether to reuse a geodatabase that contains the schema of the data you want to replicate. This reduces the amount of time required to replicate the data. This option is only available for checkout replicas
| String |
in_usefilter (optional) | The filter limits extraction to features that either intersect or are contained by features in the in_features feature layer.
| Boolean |
in_filtertype (optional) | Specifies the spatial relationship between in_datasets and in_features.
| String |
in_features (optional) |
Feature layer with one selected feature. | Feature Layer |
Codebeispiel
This stand-alone Python script extracts production mapping sample data from an ArcSDE geodatabase. The script extracts data based on a single selected feature describing an AOI.
