History

Date Posted to GIS:
2003
  • 1997: The GIS department obtained ocean and shoreline information from the Provincial governments Terrain Resource Information Management (TRIM) project.
  • 2003: A distinct islands feature class was created from the original oceans and shoreline TRIM data. The accuracy of these islands was significantly augmented by confirming locations using colour orthoimagery in 2003.

Quality

Accuracy
  • As per TRIM specifications and augmented by digitizing from 2003 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.
  • Includes most islands in the Metro Vancouver area.

Maintenance

The GIS department digitizes any updates into this dataset from the most recent orthoimagery.
