Selected Digital Mapping Projects

Route Mapping

Parcel maps using 1:50,000 digital base showing Ontario Hydro ownership over several townships were prepared by Fairhall, Moffatt & Woodland Limited for Ontario Hydro.

Municipal Inventory Map Book

Work included the preparation and publishing of a Municipal Operations Inventory Map Book for the City of Kanata in both digital and hardcopy deliverables showing property parcels, street address, lighting, sewer, water and road data compiled and converted from Land Registry Office records and engineering as-built drawings.

Lynwood Village

Integrated horizontal and vertical control data together with a cadastral parcel base overlaid on 1:500 topographic mapping was provided to the City of Nepean. The database was constructed by combining actual field tie-ins with a compilation of dimensions reported on surveys and Land Registry Office records. Digital deliveries included a feature code table to link graphic elements to text attribute data.

Indian Reserves

Fairhall, Moffatt & Woodland Limited performed data conversion of maps and plans for Garden River, Tyendinaga, Moravian, Chippewa, Munsee and Alderville Indian Reserves to create digital property parcel overlays with parcel centroids linked to a text data base for use in property administration.


The Property of Ontario Land Registration Information System (POLARIS) is a data conversion project where property parcel maps are generated in digital form using documents found in the Province's Land Registry System, as well as those typically kept by Utility, Municipal and Transport agencies. The digital map is designed to reflect all significant aspects of title and extent found in documents that may date back as far as the 1800's. Certain portions of the database are published in hard copy on standard sheet sizes and are made available to the public through the Ministry of Consumer and Commercial Relations.

Coordinate Geometry techniques are used to enter vector data found in the various land related documents. A hierarchy, based on favouring more recently prepared land documents over older ones is applied in the case of conflicting data. Field ties are measured in the map building process using Satellite Positioning Technology (GPS) to locate survey plans and documents on a 6 Transverse Mercator projection, as well as provide for data entry control, error checking and error distribution.

This process purportedly provides as accurate a parcel base as is possible in urban and urban fringe areas, without actually resurveying the Province. In rural areas, topographic mapping is digitized, so that road, fence and natural features can be used to assist in the delineation of parcel boundaries.

For very remote areas and areas where it is unlikely that the cost of building a parcel base may be recovered by user transactions or the sale of data to planning agencies, an alternate set of procedures is used resulting in a cost-effective, yet schematically complete, parcel map very similar in appearance to the more traditional POLARIS map.

The project is ongoing, scheduled to be completed by the year 2003 and is estimated to consist of some 4,000,000 parcels. It is contemplated that the parcel maps, together with the digital base, which contains a great deal more information than is actually published on hard copy, will be of great use and benefit to planning, engineering, demographic and environmental applications. Combining physical with theoretical land related data, POLARIS is one of the most ambitious digital mapping projects to date.

The Joint Venture Consortium, managed and operated by Fairhall, Moffatt & Woodland Limited, have some 200,000 parcels currently under contract, with mapping for 95% of these completed and delivered. Our staff is fully trained and certified in the comprehensive procedures and specifications for this project. The areas mapped to date cover a broad spectrum of a variety of regions, with local, historically-differing Registry and Cadastral practices and standards. We have been able to successfully accommodate all these variations in the digital map building process.
