ParcelMap BC data is continually updated by the ParcelMap BC Operations team. 

New plans and other parcel fabric updates enter the maintenance queue upon registration or confirmation, with an updated publication service target of approximately two business days.

How Survey Plan Datasets are Used to Update ParcelMap BC 

The ParcelMap BC fabric is continually updated using the best authoritative sources, including event triggers and attributes direct from the land title register for completeness. Attributes on titled parcels, Crown land parcels and the Crown land registry are also included. Spatial representations are maintained based on digital Survey Plan Datasets submitted by land surveyors based on the legal plan filings as required by the Surveyor General.

The ParcelMap BC Operations team follow defined procedures based on operational assessments when integrating a Survey Plan Dataset to update ParcelMap BC. Two join techniques are possible for this integration, depending on the fit of the new survey data in relation to the existing parcel fabric’s location and shape.

Regardless of which technique is performed, the survey dimensions and ties to control points reflecting the survey plan - as supplied by the land surveyor in the Survey Plan Dataset - are always preserved in ParcelMap BC to support future Spatial Improvements.

Type 1 Joins

Type 1 Join: Fit Survey Plan Dataset to Existing Parcel Data 

In the scenario where a Survey Plan Dataset is to be integrated to ParcelMap BC where the location and linework of the incoming survey spatially aligns (within measured tolerance) with the existing parcel fabric, a Type 1 Join will generally be performed. This scenario occurs when the existing parcel fabric is of high quality, such as where there was a previously integrated Survey Plan Dataset or where survey dimensions for the parcels were manually captured in the fabric from a survey plan. A Type 1 Join results in the Survey Plan Dataset being fit to the location of existing parcel points such that the shape and location of the existing parcel representations are preserved. See figures below for the representation of the parcel fabric before and after a Type 1 Join

Type 1: Pre-Join

The incoming Survey Plan Dataset (green lines) closely aligns with the shape and location of the existing underlying parcel fabric (red lines).

Type 1 Pre-Join

Type 1: Post Join

Linework for the incoming Survey Plan Dataset have snapped to fit the underlying parcel fabric (red lines), as indicated by the highlighted blue lines.

Type 2 Joins

Type 2 Join: Update Parcel Data to Fit Survey Plan Dataset

In the scenario where a Survey Plan Dataset is to be integrated to ParcelMap BC and the location and linework of the incoming survey does not spatially align with the existing parcel fabric, a Type 2 Join will generally be performed. This scenario generally occurs when the location and/or shape of the existing parcel fabric is of lower or uncertain quality, such as for parcels where the location and survey dimensions were inversed from stakeholder supplied sources during the initial build of ParcelMap BC. A Type 2 Join results in the location and shape of the Survey Plan Dataset being held fixed and the existing parcel points being fit to the corresponding points in the new survey.  Consequently, the shape and location of the incoming Survey Plan Dataset is preserved and those of the underlying parcels are updated. See figures below for a representation of the underlying parcels before and after a Type 2 Join.

Type 2: Pre-Join

The existing underlying parcel fabric (red lines) does not spatially align with those of the incoming Survey Plan Dataset (green lines).

Type 2: Post Join

The highlighted blue lines indicate where existing parcel fabric (red lines) has snapped to fit the shape and location of the incoming Survey Plan Dataset. The underlying fabric parcels are neatly aligned to the new survey.
