Ownership Parcel Fabric


Sample of Ownership Parcel Fabric
The Ownership Parcel Fabric (OPF) provides a spatial and database representation of the ownership and address information for all registered titled parcels or unregistered (Approved Tentative) parcels within Calgary city limits. Features include parcel shapes, addresses and areas as well as base data such as plan, block and lot numbers and street names.

OPF is derived from Legal Survey Fabric (LSF) files in conjunction with instrument documents from the Alberta Land Titles office. The information in these files includes address, municipal address, street names, parcel type (reserve, residential, school), and detailed site information.

In the case of more complex parcels such as campuses, residential developments and shopping centres, site details are added to provide detailed locations.
