History

Date Posted to GIS:
2003
  • 2003: The spatial extents of roads were originally digitized from the 2003 orthoimagery. In 2007 additional modifications to roads were digitized from the most recent orthoimagery.
  • 2007: As part of the District of North Vancouver's asset management program, major changes to the roads schema were made. The roads feature class was segmented into sections spanning from intersection to intersection. A separate road base table was then created containing a record for each of these segments and a date for when the road base was laid was assigned.
  • 2009: Subsequently, the roads feature class was then further subdivided into sub-segments. Each sub-segment represents a unique paving date. Individual sub-segments have the same ID as its parent segment. Parent segments link to the road base table.
  • 2010: Additional cleaning of segments and changes to some IDs were made. Some spatial corrections were made as per features identified in the 2009 orthoimagery.

Quality

Accuracy
  • Digitized from 2009 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
  • Spatial information is known to be complete, expected to be complete or very close to complete.

Maintenance

GIS department contacts Street department for the latest updates. A binder full of marked-up maps depicting the extent of what was paved and when it was paved is submitted to the GIS department towards the end of the year - typically November. Paving of roads are updated accordingly.
