NOTE: Requires ArcGIS Survey Analyst extension
Cadastral fabrics are parcel datasets that are created and maintained using data from survey plans. Fabric editing tools in Survey Analyst facilitate the creation of parcels from recorded boundary line measurements from plans or plats.
A cadastral fabric is a continuous, integrated surface of connected parcels, representing the complete survey record for an area of land.
Dimensions in the cadastral fabric are edited in response to a change in the survey record; for example, a parcel split or resurvey. Parcel boundary line dimensions in the cadastral fabric match the dimensions on the survey record. Parcels that are edited or replaced by new survey records are retained as historic, thus always preserving the original survey record. Parcel polygons are also linked to each other by connection lines. Because every parcel is either linked or connected, a seamless network of connected parcel boundaries, or cadastral fabric, is formed. Parcel lines have endpoints, which are the parcel corners. Parcel corner points are common between adjacent parcel boundaries, establishing connectivity and maintaining topological integrity in the network.
For more information on cadastral fabrics and the cadastral editor, start with the topic An overview of Survey Analyst - Cadastral Editor.
Cadastral fabrics in ArcCatalog
In the Catalog tree, feature datasets containing cadastral fabrics in an Oracle database management system (DBMS) look like any other feature dataset. The difference is they contain cadastrl fabrics.
The following is an example of a cadastral fabric in a feature dataset.

Cadastral fabrics in an Oracle DBMS
Several tables are created in the database to track information about cadastral fabrics. Tables are created in the schema of the user who creates a cadastral fabric. The tables are as follows:
