Append Parcel Fabric (Parcel Fabric)

Summary

Appends one or multiple parcel fabrics into an existing target parcel fabric. The spatial reference of the input parcel fabrics must match the spatial reference of the target parcel fabric.

Usage

• Use this tool to add new parcels into existing parcel fabrics. For example, you can append a new subdivision entered by the city’s public works department into the county assessor’s database of tax parcels. Another example would be to stitch parcel fabrics from different counties into one single parcel fabric.

• Coincident boundary points are merged between appended fabrics so that the internal parcel fabric topology remains intact.

• The Append parcels as Unjoined Group option appends new parcels as unjoined groups. Unjoined parcels exist outside of the parcel fabric in their own local coordinate space. Unjoined parcels can be joined to the parcel fabric at any time. You would want to append parcels as unjoined if additional work is required on the parcels before they become joined to the parcel fabric layer.

• Parcels from both the input parcel fabric and the target parcel fabric will remain intact after the append, even if the parcels overlap. For example, existing parcels are not split or modified by overlapping appended parcels. Coincident points are always merged.

• If TEST is specified for Parcels Schema Type, Lines Schema Type, or Control Schema Type, the schema (field definitions) of these input parcel fabric tables must match the tables of the target parcel fabric in order for the parcels to be appended. The schema-type parameters only apply to attributes that you have added to the parcels, lines, or control points attribute tables. Parcel fabric system attributes remain the same across different parcel fabrics. If NO_TEST is specified, the attributes of the input parcels, lines, or control points fabric tables (field definitions) do not have to match the tables target fabric dataset. However, any fields from input parcel fabric tables that do not match the fields of the target parcel fabric tables will not be mapped. Fields are only mapped between the input parcel fabric and target parcel fabric if the same fields exist in both fabrics.

• The spatial references of the input and target parcel fabric must match. The tool cannot append a parcel fabric that has a spatial reference that is different from the spatial reference of the target parcel fabric.

• The upgrade versions of the input and target parcel fabric must match.

• Parcel fabric layers can be used as Input Parcels. If a parcel fabric layer has a selection, only the selected parcels are used.

• This tool cannot use multiple input parcel fabric layers with the same name. Although ArcMap allows for the display of parcel fabric layers with the same name, these layers may not be used. To work around this limitation, use the tool dialog box browse button to browse for the full paths of each of the Input Parcels.

• To use the Parcels Subtype, Lines Subtype, and Control Points Subtype parameters, the target parcel fabric must have defined subtype fields and assigned subtype codes on the parcels, lines, and control points tables. In the Parcels Subtype, Lines Subtype, or Control Points Subtype parameters, provide a subtype description to assign that subtype to all new parcel fabric features that are appended to the target parcel fabric.

Syntax

AppendParcelFabric_fabric (in_parcels, target, unjoined_group, {parcels_schema_type}, {field_mapping_parcels}, {parcels_subtype}, {lines_schema_type}, {field_mapping_lines}, {lines_subtype}, {control_schema_type}, {field_mapping_control}, {control_subtype})

Parameter	Explanation	Data Type
in_parcels	The input parcel fabrics that will be appended into the target parcel fabric. The spatial reference of the input parcel fabric must match that of the target parcel fabric.	Parcel Fabric Layer
target	The existing parcel fabric that the input parcel fabrics will be appended into. The spatial reference of the input parcel fabric must match that of the target parcel fabric.	Parcel Fabric
unjoined_group	Determines how parcels will be appended. UNJOINED_GROUP —Parcels will be appended as unjoined, stand-alone parcels to the parcel fabric. JOINED_GROUP —Parcels will be appended as joined parcels to the parcel fabric.	Boolean
parcels_schema_type (Optional)	Specifies if the schema (field definitions) of the input parcel fabric parcels table must match the schema of the target parcel fabric parcels table in order for data to be appended. TEST —Input parcel fabric parcels table schema (field definitions) must match the schema of the target parcel fabric parcels table. An error will be returned if the schemas do not match. NO_TEST —Input parcels table schema (field definitions) does not have to match that of the target parcels table. Any fields from the input parcels table that do not match the fields of the target parcels table will not be mapped to the target parcels table unless the same fields exist in the target parcels table.	String
field_mapping_parcels (Optional)	Lists the attribute fields that will be mapped to the target parcels table. The list includes the existing attribute fields of the target parcels table and attributes fields that match between the input parcels table and the target parcels table. Because the input parcel fabric is appended into an existing target parcel fabric that has a predefined schema (field definitions), the Parcels Extended Attribute Field Map control does not allow for fields to be added or removed from the target parcel fabric.	Field Mappings
parcels_subtype (Optional)	A subtype description to assign that subtype to all new parcel features in a parcel fabric which is appended to the target parcel fabric.	String
lines_schema_type (Optional)	Specifies if the schema (field definitions) of the input parcel fabric lines table must match the schema of the target parcel fabric lines table in order for data to be appended. TEST —Input parcel fabric lines table schema (field definitions) must match the schema of the target parcel fabric lines table. An error will be returned if the schemas do not match. NO_TEST —Input lines table schema (field definitions) does not have to match that of the target lines table. Any fields from the input lines table that do not match the fields of the target lines table will not be mapped to the target lines table unless the same fields exist in the target lines table.	String
field_mapping_lines (Optional)	Lists the attribute fields that will be mapped to the target lines table. The list includes the existing attribute fields of the target lines table and attributes fields that match between the input lines table and the target lines table. Because the input parcel fabric is appended into an existing target parcel fabric that has a predefined schema (field definitions), the Lines Extended Attribute Field Map control does not allow for fields to be added or removed from the target parcel fabric.	Field Mappings
lines_subtype (Optional)	A subtype description to assign that subtype to all new line features in a parcel fabric which is appended to the target parcel fabric.	String
control_schema_type (Optional)	Specifies if the schema (field definitions) of the input parcel fabric control table must match the schema of the target parcel fabric control table in order for data to be appended. TEST —Input parcel fabric control table schema (field definitions) must match the schema of the target parcel fabric control table. An error will be returned if the schemas do not match. NO_TEST —Input control table schema (field definitions) does not have to match that of the target control table. Any fields from the input control table that do not match the fields of the target control table will not be mapped to the target control table unless the same fields exist in the target control table.	String
field_mapping_control (Optional)	Lists the attribute fields that will be mapped to the target control table. The list includes the existing attribute fields of the target control table and attributes fields that match between the input control table and the target control table. Because the input parcel fabric is appended into an existing target parcel fabric that has a predefined schema (field definitions), the Control Points Extended Attribute Field Map control does not allow for fields to be added or removed from the target parcel fabric.	Field Mappings
control_subtype (Optional)	A subtype description to assign that subtype to all new control point features in a parcel fabric which is appended to the target parcel fabric.	String

Code Sample

# Name: Append Parcels.py 
# Description: Appends a new subdivision to the county's Parcel Fabric

# Import system modules
import arcpy
from arcpy import env

# Set workspace
env.workspace = "E:\City\LocalGovernment.gdb\ParcelEditing"

# Set local variables
