S-100

New S-100 Service

The pilot project has finished and a new S-100 Service has launched.  S-102 Bathymetric Surfaces and S-111 Surface Currents are now available to purchase through a subscription service.

S-102 Bathymetric surface user trials

The International Hydrographic Organization’s S-100 universal hydrographic data model introduces dynamic hydrographic product capabilities.

CHS launched a pilot project in collaboration with ECC/PRIMAR and Teledyne CARIS to provide S-100 products to the Canadian marine community under that standard over the next year.

The first stage is to provide the community with high-definition bathymetry files (S-102 datasets). These products would offer a digital elevation model that represents the seafloor in a regular grid. It can be used as a standalone product or as an overlay on a navigation system.

ECC/PRIMAR and Teledyne CARIS developed software to allow uploading, hosting, managing and delivering of S-100 products. Trials are underway in Canada and Norway among marine pilots.

The objectives of the pilot project are to:

  • Implement an innovative bathymetric data service that will prove the value of the S-100 data standards
  • Demonstrate the increased navigation efficiency available using S-102 datasets
  • Prove the capabilities of S-102 bathymetry to users and manufacturers to promote the development of ECDIS/ECS/PPU software
  • Encourage the use of high-definition bathymetry over nautical charts
  • Determine the cost elements of operating an S-102 data service
  • Help in developing a business- and licensing model for S-102 datasets

Notice of interest for the development of S-102 product display applications and software

We invite manufacturers involved in designing Electronic Chart Display and Information Systems (ECDISs), Electronic Chart Systems (ECSs) and Portable Pilot Units (PPUs) to take an interest in the new S-102 products, to develop software using this data, and to participate in our user trials.

The Canadian Hydrographic Service provides "UNOFFICIAL, NOT FOR NAVIGATION" files of these products to support you in developing this software. You will find these S-102 files at the bottom of the page.

Field Surveys

Field Data (Digital)

Modern hydrographic surveys are conducted using the latest satellite positioning technology, advanced multibeam bathymetric data collection systems, and powerful data processing, analysis and portrayal tools.

For information on available digital hydrographic data, please visit the CHS NONNA Data Portal.

Field Sheets (Hardcopy)

CHS has an extensive collection of hydrographic survey data in the form of field sheets based on over 100 years of surveying in Canada. Data has been collected using a wide range of methods and systems, from lead-line to modern day multi-transducer and multibeam systems. Positions have been established using the different types of terrestrial systems and methods available over many years - up to the latest advanced satellite positioning systems.

For information on available field sheets, please email us at chsinfo@dfo-mpo.gc.ca.

Hydrographic Surveys

CHS hydrographers are actively engaged in surveying and measuring Canada’s inland navigable waterways out to the edge of the continental shelf and beyond, the Great Lakes, and the Atlantic, Pacific and Arctic Ocean coasts. The data collected by hydrographers is used to produce authoritative nautical charts and publications and to support a broad range of marine activities.

Hydrographic surveys capture water depths, geographical features, hazards to navigation, man-made and natural features that aid navigation, tides, currents and water levels, and sea bottom characteristics. We follow rigorous, internationally-recognized standards and guidelines when we conduct hydrographic surveys.

Bathymetry

The Canadian Hydrographic Service (CHS) CHS NONNA bathymetric data

CHS offers a complete inventory of bathymetric data free to the general public for non-navigational use. We call them 'CHS NONNA' for the 'non-navigational' purpose of the data and the product is available in a spatial resolution of 10 metres or 100 metres.

This data represents a consolidation of digital bathymetric sources managed by the CHS. The CHS NONNA-10 products are a ten-fold improvement over its data predecessor, CHS NONNA-100. Both are a significant improvement in detail and accuracy over the 500-metre data we formerly had available to the general public. Images on this page show the difference in the level of detail before the CHS NONNA-100 and CHS NONNA-10.

The CHS NONNA data is accessible free of charge, both to view or download in various formats, to anyone interested in Canada’s marine space. You may access all CHS NONNA bathymetric data on Open Data (available to the public) or on the Federal Geospatial Platform (available to Government of Canada employees).

Bathymetric Maps

CHS’s bathymetric maps contain a wealth of detail about the nature of the seafloor and the material beneath it. These maps are generally of interest to users whose prime focus is not navigation. This data is available under a free licence from the following link.

Magnetic and gravity maps are available from the Geological Survey of Canada.

General Bathymetric Chart of the Oceans

CHS actively participates in and contributes bathymetric data to the General Bathymetric Chart of the Oceans (GEBCO), an international group of experts on ocean mapping.

For more information, refer to GEBCO's website.

High-water Line for British Columbia

The CHS Pacific High Water Coastline Dataset is a high resolution vector coastline that represents the Higher High Water Large Tides mark in BC’s tidal waters.

This shapefile format coastline is derived from a compilation of sources including modern satellite imagery and other CHS data products and is designed for GIS users in the non-navigation community.
