Validate Parcel Fabric (Parcel)

Summary

Validates a parcel fabric using a predefined set of geodatabase topology rules and any other topology rules you have added for your organization.

The parcel fabric uses geodatabase topology rules to define parcels and model their behavior. Geodatabase topology rules define the spatial relationships between parcel features. You can define additional geodatabase topology rules to manage and enforce data quality standards in your organization.

Legacy:

This is a deprecated tool. The parcel fabric geodatabase topology can be validated using the Validate Topology tool.

Usage

• Use this tool to validate an entire parcel fabric dataset or a large number of parcels.

• The parcel fabric topology must be enabled.

• Dirty areas in the validated extent will be removed. Dirty areas are created when data is added to or modified in the parcel fabric.

• After validation, rule errors can be viewed by opening the Error Inspector pane. Rule errors are violations of topology rules and are displayed in the Point Errors, Line Errors, and Polygon Errors sublayers under the parcel fabric layer.

Parameters

Dialog

Label	Explanation	Data Type
Input Parcel Fabric	The parcel fabric to be validated. The parcel fabric can be from a file or mobile geodatabase or from a feature service.	Parcel Layer
Extent (Optional)	The extent of the dataset to be processed. Only features that fall within the specified extent will be processed. Current Display Extent —The extent will be based on the active map or scene. This option is only available when there is an active map. Draw Extent —The extent will be based on a rectangle drawn on the map or scene. This option will create a feature class in the project geodatabase and add a layer to the map. The feature class will have the same coordinate system as the map. Note: This option is not available in the Environments dialog box. It is only available from a tool parameter with an extent data type or from the Environments tab on a tool dialog box. Note: When the Enable and disable editing from the Edit tab editing option is checked, you must enable editing on the Edit ribbon tab to draw the extent. Extent of a Layer —The extent will be based on an active map layer. Use the drop-down list to choose an available layer or use the Extent of data in all layers option to get the combined extent of all active map layers, excluding the basemap. This option is only available when there is an active map with layers. Each map layer has the following options: All Features —The extent of all features in the layer. Selected Features —The extent of the selected features in the layer. Visible Features —The extent of visible features in the layer. Note: The extents from the Selected Features and Visible Features options are only available for feature layers. Browse —The extent will be based on an existing dataset. Intersection of Inputs —The extent will be based on the minimum or intersecting extent of all inputs. If no inputs overlap, a null extent with all zeros will result. Union of Inputs —The extent will be based on the maximum or combined extent of all inputs. Clipboard —The extent can be copied to and from the clipboard. Copy Extent —Copies the extent coordinates and coordinate system to the clipboard. Paste Extent —Pastes the extent coordinates and, optionally, the coordinate system from the clipboard. If the clipboard values do not include a coordinate system, the extent will use the map’s coordinate system. Note: The extent coordinates are copied to and pasted from the clipboard using the same formatting and order as the ArcPy Extent object: x-min, y-min, x-max, y-max, and the spatial reference. Reset Extent —The extent will be reset to the default value. Manually entered coordinates—The coordinates must be numeric values and in the active map's coordinate system. Caution: The map may use different display units than the entered coordinates. The use of a cardinal direction (N, S, E, W) is not supported. Use a negative value sign for south and west coordinates.

Python

arcpy.parcel.ValidateParcelFabric(in_parcel_fabric, {extent})

Name	Explanation	Data Type
in_parcel_fabric	The parcel fabric to be validated. The parcel fabric can be from a file or mobile geodatabase or from a feature service.	Parcel Layer
extent (Optional)	The extent of the dataset to be processed. Only features that fall within the specified extent will be processed. MAXOF—The maximum extent of all inputs will be used. MINOF—The minimum area common to all inputs will be used. DISPLAY—The extent is equal to the visible display. Layer name—The extent of the specified layer will be used. Extent object—The extent of the specified object will be used. Space delimited string of coordinates—The extent of the specified string will be used. Coordinates are expressed in the order of x-min, y-min, x-max, y-max.	Extent

updated_parcel_fabric	The validated parcel fabric.	Parcel Fabric

Code sample

ValidateParcelFabric example (Python window)

The following Python window script demonstrates how to use the ValidateParcelFabric function in immediate mode. The script validates parcels using the combined extent of all input data (MAXOF).

import arcpy
arcpy.parcel.ValidateParcelFabric("C:/Data/Database.gdb/Parcels/CountyFabric", 
                                  "MAXOF")

Environments

This tool does not use any geoprocessing environments.
