Geographic Township Improved Coordinate system: 4269 - "NAD83" Abstract: This data set is a polygon coverage that can be used to identify the location of townships in the province of Ontario. A township is a fundamental land subdivision in the original survey fabric of the province as completed by the Crown. A polygon feature that identifies a surveyed area that may or may not comprise of lots and concessions. The spatial accuracy for some of the township fabric from the NRVIS and the LIO warehouse was improved through the Ontario Parcel, Township Realignment and Township Improvement projects. Improvements to the fabric may include: road allowance widths spatial changes to better represent where the township boundaries are located more consistent concession names Materials used to improve the location of township lines may include: Township Improvement plots survey information (i.e. retracements) original township plans surveys notes, etc. NRVIS physical features such as fencelines, and water bodies GPS Ontario Road Network geometry Other township improvement materials were also used to improve the lot fabric in some townships. Please note: not all townships have been improved. Supplementary tables can be used and are available for download from the additional documentation section. Supplementary look-up table descriptions are available in the data description document, which is available for download from the additional documentation section. This layer is part of what was known as the OMNR Fundamental Dataset.

  Ontario Ministry of Natural Resources: Township Improvement Materials (NRVIS): The objective of the Township Fabric Improvement project was to obtain as much survey information on certain subdivided townships from the best possible source in order to enhance the spatial representation of the fabric in a digital database. Through the acquisition of Ontario Land Surveyors' records and opinions, GIO obtained survey information that may better indicate where some lot and township corners should be positioned. Township Improvement includes materials and survey information provided by local surveyors. This information was incorporated into the Ontario Parcel build. Please note: Not all townships were improved, depending upon available survey information and whether there was interest from the surveyor to do the work. The improved fabric from both the Township Improvement/Ontario Parcel projects will be inserted into a new township fabric data model that will reside in both NRVIS and the LIO warehouse. Data collected from 01/01/2000 to 30/06/2005. Local surveyor marked up hard copy plots to indicate where lot/township corners could be better positioned. This information was based on their available survey records. Relevant information may include: lot corners that can be referenced to physical features, such as fences, roads, transmission lines, wooded areas, rivers and lakes (which would be shown on the plans); surveyed dimensions between corners, or if available, the co-ordinate values for lot corners that are tied to geodetic control. The surveyor may have also confirmed that lot corners are correctly located. Approximately 500 subdivided township had some work done on them - anywhere from 1 lot corner to hundreds confirmed or improved. The marked-up plots were provided to the Ontario Parcel build contractors to incorporate in the parcel build.

  Teranet: Township Realignment - Basic Index Mapping (BIM) and Province of Ontario Registration and Information System (POLARIS): Township Realignment Project - For 230 townships in southern Ontario where Teranet's POLARIS and BIM mapping exist, the NRVIS township fabric was realigned with the fabric and parcels from POLARIS and BIM mapping. The POLARIS and BIM parcel fabric data was used to build the NRVIS fabric, because it is deemed to be more accurate than the present NRVIS township fabric. The data used from the BIM and POLARIS to improve the township fabric included: parcels, subdivision plans, reference plans and varies other types of plans.

  Ontario Ministry of Natural Resources: Ontario Parcel Build /NRVIS Lot (NRVIS): NRVIS Township Fabric - As part of the Ontario Parcel build contract, existing NRVIS geographic township fabric was confirmed (to MNR materials) prior to its use in the Ontario Parcel build. Should the build Contractor determine that the position of MNR's NRVIS geographic township fabric was unacceptable, the Contractor was to improve the geographic township fabric based on the materials provided by MNR. If the contractor did not have any better information that would improve the township fabric, then they were instructed to leave the fabric as it already exists in NRVIS. Materials and information provided to the Ontario Parcel build contractors included: Township Improvement materials (plots, retracements, original township plans, some highway plans), Ontario Road Network geometry, NRIVS data such as fences, hedges, and hydrology and assessment maps. The build contractors were to follow the methods of retracement as set out in the Surveyor's act when building the townships.Improvement to the township fabric included: - Road allow widths - More consistent concession names,- Spatial change to the position of some lot/ township corners - Changes to water edges - Where a body of water now exists, as shown in NRVIS, but does not appear on the original twp. plan or where the size and/or shape of a body of water is significantly different between that as shown in NRVIS and as shown on the origninal twp plan, the fabric has been improved to show the original extent of the lots where appropriate.
