Enable the information model on your parcel fabric
This topic applies to ArcGIS for Desktop Standard and ArcGIS for Desktop Advanced only.
Now that you are familiar with creating and editing a parcel fabric, you can enable the parcel fabric with the Local Government Information Model.
The Local Government Information Model is based on a harmonized information model of GIS datasets, web services, and maps that connect information and integrates processes across typical government departments.
When a parcel fabric is enabled with the Local Government Information Model, tax parcels, subdivisions, lots, encumbrances and survey framework are organised in the parcel fabric layer and are edited in workflows using the Parcel Editor toolbar. Parcel types, attributes, and domains that reflect the editing requirements of Local Government parcel maintenance are added to parcel fabric tables. The parcel fabric layer is displayed and symbolized using the Local Government configuration, and the parcel fabric can be used in efficient and automated parcel editing workflows.
The parcel fabric can be used by mapping technicians in an Assessors office, Public Works agencies, Register of Deeds offices of any other agency responsible for managing land records.
Type your parcels
Before enabling the Local Government Information Model on your parcel fabric, you need to ensure that you have typed your parcels using the Local Government parcel types.
- If you have an empty parcel fabric, it is recommended that you type your parcels prior to loading them into the parcel fabric. That way you can more easily load overlapping parcel types.
- If you have an existing parcel fabric, you can type the parcels that are already in your parcel fabric.
The Local Government Information Model uses the following parcel types:
Type | Description |
|---|---|
1 | PLSS Township |
2 | PLSS Section |
3 | PLSS Quarter Section |
4 | Special Survey |
5 | Simultaneous Conveyance |
6 | Conveyance Division |
7 | Tax |
8 | Ownership |
9 | Encumbrance |
10 | Separated Right |
11 | Other |
Configure the parcel fabric layer
The parcel fabric layer is displayed and symbolized using the Local Government configuration. Parcels are displayed by parcel type in a series of sublayers:
Sub Layer | Parcel Type |
|---|---|
Historic Parcels | Type = 7, 9, 6 |
Cadastral Framework | Type = 1, 2, 3 |
Subs and Condos | Type = 5 |
Tax Parcels | Type = 7 |
Lots and Units | Type = 6 |
Encumbrances | Type = 9 |
Note:If you have no parcel types or use different numbering for your parcel types, your parcels will not display in the parcel fabric layer.
Each parcel sublayer references the parcel fabric Parcels table, which is configured differently for each parcel type. For example, the Name system attribute on the Parcels table has an alias named Parcel Identification Number for the Tax Parcels sublayer and an alias of Lot or Unit Number for the Lots and Units sublayer. Different attributes are turned on and off for editing.
The Historic Parcels, Subs and Condos, Lots and Units, and Encumbrances sublayers are displayed using attribute domains. You need to ensure that you have specified attribute domains for these parcel types.
Tip:To view the parcel fabric Parcels table, use the Make Parcel Fabric Table View geoprocessing tool under System Toolboxes > Layers and Table Views.
Tax Lines Anno layer
The Tax Lines Anno layer is an annotation layer that references the ParcelDimensions annotation feature class in the ParcelEditing feature dataset. The annotation layer is feature linked to the parcel fabric lines and contains annotation at a 1:1,200 scale. Annotation is derived from the Distance, Bearing and Radius attributes on the parcel fabric Lines table.
Control layer
Displays parcel fabric control points. Control points are displayed and symbolised by the Control Type field in the parcel fabric Control table. Parcels can be adjusted to the control point network in the parcel fabric.
Line Points layer
Displays parcel fabric line points. By default, the Line Points layer is turned off.
Points layer
Displays parcel fabric points. Points are displayed and symbolised as boundary points and center points using the Center Point field in the parcel fabric Points table.
Lines layer
Displays parcel fabric lines. By default the Lines layer is turned off. Lines are displayed and symbolised using the Category field on the parcel fabric Lines table.
Historic Parcels layer
Displays historic parcels from the parcel fabric Parcels table. For the Historic Parcels layer, the Parcels table is queried to display parcels of type 7 (tax), type 9 (encumbrance), and type 6 (lots). The definition query "SystemEndDate IS NOT NULL" is used to query for historic parcels.
The layer is further symbolized using the Reason Parcel Retired field in the parcel fabric Parcels table , which uses the lrHistoryType attribute domain.
Learn more about historic parcels in the parcel fabric
By default, the Historic Parcels layer is turned off.
Cadastral Framework layer
Displays PLSS parcels. For the Cadastral Framework layer, the parcel fabric Parcels table is queried to display parcels of type 1 (PLSS Township), type 2 (PLSS Section) and type 3 (PLSS Quarter Section). The layer has been symbolized using the Parcel Type field in the Parcels attribute table.
The Public Land Survey System (PLSS) represents townships and ranges. Each township is divided to sections (first division). Each section is further divided to aliquot parts or government lots. The second division may extend to the quarter or quarter-quarter division of a section.
Subs and Condos layer
Displays nonhistoric subdivisions and condominiums. For the Subs and Condos layer, the parcel fabric Parcels table is queried to display parcels of type 5 (Simultaneous Conveyance). The layer has been symbolized using the Parcel Type field in the Parcels attribute table.
The layer is further symbolized using the Sub or Condo Type field in the parcel fabric Parcels table , which uses the lrSimConType Type attribute domain.
Tip:The layer is currently symbolised to display only subdivision and condominium values. There are additional values that you can use from the lrSimConType attribute domain.
Tax Parcels layer
Displays nonhistoric tax parcels. For the Tax Parcels layer, the parcel fabric Parcels table is queried to display parcels of type 7 (Tax).
Lots and Units layer
Displays nonhistoric lots and units. For the Lots and Units layer, the parcel fabric Parcels table is queried to display parcels of type 6 (Conveyance Division).
The layer is further symbolized using the Lot or Unit Type field in the parcel fabric Parcels table , which uses the lrSimConDivType attribute domain.
Tip:There are additional values that you can use from the lrSimConDivType attribute domain that are currently not used to symbolise the layer.
Encumbrances layer
Displays nonhistoric encumbrances. For the Encumbrances layer, the parcel fabric Parcels table is queried to display parcels of type 9 (Encumbrance).
The layer is further symbolized using the Encumbrance Type field in the parcel fabric Parcels table , which uses the lrEncumbranceType attribute domain.
Encumbrances are limitations on the rights and use of the land. Easements are a common encumbrance, but there are many others such as grazing rights, fishing rights, development rights, and floodplains.
Enable the information model
A parcel fabric can be enabled with the Local Government Information Model in the Catalog window. Right-click your parcel fabric, point to Information Models, and click Enable Information Model to run the Enable Fabric Information Model wizard.
The Local Government Information Model uses a feature-linked annotation class (feature linked to parcel fabric lines). If you have an existing lines feature-linked annotation class, the Enable Fabric Information Model wizard detects and uses the annotation class. If no lines feature-linked annotation class is detected, a new lines feature-linked annotation class is created.
If schema errors are found during the enabling process, the parcel fabric will not be enabled with the Local Government Information Model. Schema errors are listed on the Information model report page of the Enable Fabric Information Model wizard and need to be corrected before your parcel fabric can be enabled with the Local Government Information Model.
Once you have successfully enabled your parcel fabric with the Local Government Information Model, you can use automated parcel editing workflows. To access the workflows, click Parcel Editor > Parcel Workflows.
