Abstract
A total of six web services is now being offered by the Canadian Hydrographic Service.
3 Web services providing access to official water level data:
the Canadian Hydrographic Service (CHS) has developed three web-based water level services, and they are available free of charge under licence. Specifically, these three web services provide access to water level predictions, water level observations, and SPINE (Service de Prévision et d’Interpolation des Niveaux d’Eau), a water level forecasting and interpolation system.
3 Web services providing access to official data for navigating modelled surface currents:
the Canadian Hydrographic Service has developed three web-based modelled surface currents. The first produces dynamic images of the data according to the specified parameters. The second one is a WFS that recovers the raw data behind the images, and the third is a WCS that recovers raw data from only the raster layers. These web services are also available free of charge, under licence.
