History

Date Posted to GIS:
2005
  • 2003: Originally, tidal flat information was entered into the GIS by heads-up digitizing 2003 orthoimagery.
  • 2007: This dataset has been updated by digitizing the latest orthoimagery.

Quality

Accuracy
  • Locations of tidal flats is somewhat subjective. Polygons were heads-up digitized.
  • 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

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