History

Date Posted to GIS:
1997
  • 1997: The Triathlon Mapping Company provided the District of North Vancouver with orthoimagery and various features that were identified using photogrammetry. Fences were collected at this time.
  • 2000: The fence information was verified through a field study and ground truthing project. Two temporary GIS staff drove through the District and collected various asset information. Materials, types and ownership information was collected from the field and the extents of the features were marked up on hardcopy maps.
  • 2000: These hardcopy maps were then digitized into the GIS and various feature classes were created. Line work was corrected by using the most recent orthoimagery as a guideline.
  • 2007: As part of the District of North Vancouver's asset management program, parts of the Districts asset inventory was refined, augmented and completed. In some cases this involved the collection of more information which was then updated in the GIS.
  • 2012: All privately owned fences were removed as their locations and attributes could not be verified nor maintained.

Quality

Accuracy
  • Digitized from 20 cm and 10 cm orthoimagery
  • Spatial information is collected and entered using the next best method applicable to this dataset.
  • Spatial information is very accurate but could be improved using a better collection technique.
  • Where multiple collection/entry methods, the more accurate method is predominant throughout this dataset.
Completeness
  • Some spatial information may be missing.

Maintenance

GIS department contacts Streets department for the latest updates. A Streets department staff representative sits down with GIS staff and reviews and assists with the updates.
