Abstract

Accessing accurate, up-to-date data to support chart production in Canada’s vast and complex waterways can be challenging. In order to improve efficiency in charting these navigable waters, The Canadian Hydrographic Service (CHS) has developed new techniques that leverage Satellite Based Earth Observation (EO) data. The main applications developed by CHS include: Satellite Derived Bathymetry (SDB), intertidal zone mapping, extraction of accurate coastlines, change detection/rate of change of coastal features and virtual tidal gauges. The results obtained demonstrate that EO data is a reliable source of Hydrospatial information that can meet the CHS and International Hydrographic Organization (IHO) charting requirements.
