History

Date Posted to GIS:
2004
  • 2003: After 2003 it was recognized that the GIS did not show connections between catch basins and storm mains. Therefore, it was necessary to digitize the leads between the basins and the mains.
  • 2003: A special project commenced which saw each catch basin connected to its adjacent main. In many cases these leads were arbitrarily entered as no spatial information was present on the engineering drawings.

Quality

Accuracy
  • Leads are mostly digitized arbitrarily and exist just to indicate connectivity between basins and mains.
  • 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.
  • 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.
