Defects in Survey Plan Datasets

Last modified on December 28, 2022

Common Issues and How to Avoid Them When Submitting a Survey Plan Dataset

If you are required to re-submit a dataset, please ensure edits are made directly to the defect in your Survey Plan Dataset Submission dashboard. Do not make a new submission. Instead, please provide a corrected CAD file and CSV file, if necessary, and re-submit the dataset.

1. Lines Captured on the Wrong Layers in the CAD File

Defect Reason

  • Parcel lines / resolved lines / tie lines that are present in the Survey Plan are not included in the dataset.

Resolution

  • Dataset must include, on the appropriate PMBC layers, all dimensioned lines that appear in the survey plan.
  • Polylines are used for features other than Natural Boundaries.
  • Except for natural boundaries, all linework must be lines or arcs, and not polylines.
  • Lines in the dataset are captured on the wrong CAD layer.
  • Ensure all lines are on the correct CAD layer:
  •  Parcel lines within and coincident with the heavy outline must be included on the PMBC_PARCEL_LINE layer
  • Interest lines within and coincident with the heavy outline must be included on the PMBC_INTEREST_LINE layer
  • Surveyed connection lines – full length (not foreshortened), must be included on the PMBC_TIE_LINE layer
  • Additional resolved parcel boundary lines that are not included as part of layer PMBC_PARCEL_LINE or PMBC_INTEREST_LINE must be included on the PMBC_RESOLVED_LINES layer. This includes surveyed lines on a Posting Plan.  Any other CAD entities, including all scenery, must be included on the PMBC_OTHER layer
  • Radial lines are included in the dataset.
  • Radial lines generally should not be included; if they are included, they must be on PMBC_OTHER or non PMBC layers.

2. Dataset Integrity Defects
  • Lines are not broken at the surveyed parcel boundary intersection.
  • All parcel boundary lines must be broken at intersections with other surveyed parcel boundaries; lines must be broken as dimensioned.
  • Lines are not broken at the surveyed parcel boundary intersection.
  • Surveyed lines should not be broken at intersections with scenery linework
  • Gaps and overlaps exist in the line work (lines do not connect at a single vertex at intersections).
  • All linework must meet at a single vertex, without gaps or overlaps.
  • Exaggerated lines (i.e. lines to witness posts) are not provided at full grid length.
  • Lines that are exaggerated on the survey plan must be shown at their actual dimensions in the dataset.
  • Foreshortened lines (i.e. lines to distant control) are not provided at full grid length
  • Lines that are exaggerated on the survey plan must be shown at their actual dimensions in the dataset.
  • Linework is duplicated.
  • All linework must be represented by a single entity; duplicated or overlapping linework must be removed.

3. Defects Specific to Certain Plan Types
  • Parcel boundary lines in Posting Plans are shown on the PMBC_PARCEL_LINE layer.
  • Parcel boundaries on posting plan datasets must be shown on the PMBC_RESOLVED_LINES layer.
  • Individual building strata parcels are shown on the PMBC_PARCEL_LINE layer.
  • Datasets for building stratas must only show the parent parcel boundary (the heavy outline) on the PMBC_PARCEL_LINE layer. Individual building strata lots are not to be shown.
  • Individual air space parcels are shown on the PMBC_PARCEL_LINE layer.
  • Datasets for air space plans must only show the parent parcel boundary on the PMBC_PARCEL_LINE layer. The air space parcels are not to be shown.

4. Miscellaneous Defects
  • The drawing is provided in the wrong UTM grid projection.
  • Before submission, verify your dataset is in the correct UTM grid projection.
  • The drawing has been provided in ground and not grid.
  • All dimensioned lines must be provided at full grid length
  • The drawing uses an incorrect / inconsistent scale factor.
  • All dimensioned lines in your dataset must be provided at full grid length with a consistent and correct scale factor.
  • The Survey Plan Dataset contains data on PMBC layers that is not shown on the Survey Plan.
  • Only lines that are directly referenced on the Survey Plan must be included in the dataset.
  • The submission is missing control points that are shown on the Survey Plan
  • Ensure that all Control Points on the Survey Plan are captured in your submission.
