History

Date Posted to GIS:
1998
  • 1996: Parts of the water system were digitized from water drawings. This task was undertaken first by the Design section staff and then later by a number of temporary staff up until 2001. This effort to enter water information was not as accurate as the EIIS method that superseded it in 2002.
  • 2002: Between early 2002 and late 2003, as part of the Engineering Infrastructure Information System (EIIS) project, a dedicated team of technicians digitized the District's utilities infrastructure from over 14,000 engineering drawings. A model was established and objects were digitized using Microstation CAD software and later migrated to the District's GIS. All of the storm basins were digitized from engineering drawings along with their attribute information.
  • 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.
  • 2008: The Water Facilities feature class was included as features which participate in the Water geometric network (GMN). These facilities are represented as points to better facilitate the model.

Quality

Accuracy
  • As per engineering drawing
  • Spatial information is collected and entered using a compromised method applicable to this dataset.
  • Spatial information is moderately accurate and considerable improvements could be made.
  • Where multiple collection/entry methods, the more accurate method is not predominant throughout this dataset.
Completeness
  • Spatial information is known to be complete, expected to be complete or very close to complete.
  • Expected to be near or fully complete

Maintenance

The Utilities department or a contractor will submit engineering drawings to the GIS department. Utilities information is updated in the GIS as per the engineering drawing, the drawing is scanned, logged into the engineering drawing database and the hardcopy drawing is hung up in the vaults.
