New users of the CHS NONNA Data Portal are encouraged to fully review the 'CHS NONNA Data Portal Guidance Document' (PDF) which is available below in the RESOURCES section of this page. ----- PRODUCT USE ----- The Canadian Hydrographic Service (CHS) NONNA Bathymetric Data products are for NON-NAVIGATIONAL USE ONLY. Please see the CHS NON-NAVIGATIONAL BATHYMETRIC DATA LICENCE AGREEMENT in the resources section below for further terms and conditions governing the use of this data. Under the Navigation Safety Regulations, 2020, made pursuant to the Canada Shipping Act (2001), notwithstanding exceptions, vessels navigating in Canadian waters must carry and use nautical charts and related publications issued by, or on the authority of the CHS. To obtain official navigational products released by the CHS, please see: www.charts.gc.ca For bathymetry outside of Canada’s jurisdiction, please consult the appropriate Hydrographic Office. ----- PRODUCT DESCRIPTION ----- The CHS NONNA-10 and NONNA-100 Bathymetric Data products represent a consolidation of digital bathymetric sources managed by the CHS. The « NONNA » refers to NON-NAvigational. The « 10 » or « 100 » references the approximate resolution (in metres) of the data. The CHS NONNA-10 individual product coverage is as follows: • South of 68°N the products = 0.1° latitude X 0.1° longitude (0.0001 degrees) • 68°N-80°N the products = 0.1° latitude X 0.2° longitude (0.0002 degrees) • 80°N and north the products = 0.1° latitude X 0.4° longitude (0.0004 degrees) The CHS NONNA-100 individual product coverage is as follows: • South of 68°N the products = 1° latitude X 1° longitude (0.001 degrees) • 68°N-80°N the products = 1° latitude X 2° longitude (0.002 degrees) • 80°N and north the products = 1° latitude X 4° longitude (0.004 degrees) There are various valid vertical datums associated with CHS' bathymetric sources. As a result, the vertical reference of the CHS NONNA products does not conform to a unified vertical datum. Although the NONNA products are intended to include only bathymetric data, some areas may include data on land. Elevation values will appear as a positive number when querying the data in the CHS NONNA Data Portal. Please note that gaps in the data may be visible where modern surveys have not yet been conducted or where legacy data has not yet been digitized. Data sources included in the NONNA products may not have been subjected to the same level of quality assurance as those in official navigational products. The CHS NONNA products will be updated annually and made available by the last Friday of April of each calendar year. ----- PRODUCT FORMATS ----- CHS NONNA products adhere to the following naming convention: NONNA10_4360N07940W • NONNA10 = the product and will be either NONNA100 or NONNA10 • 4360N07940W = the south-west corner of the NONNA cell. These products are available to view, query and download via the CHS NONNA Data Portal. The following formats are available for download: • 32-bit GeoTIFF • ASCII++ (XYZ) • CSAR • BAG These formats can be opened using various GIS applications.

The Canadian Hydrographic Service (CHS) High Water Mark Lines provide alongshore and across-shore geomorphological and biological attributes of the high water mark shoreline. The lines are used in the CHS nautical charts to represent the level reached by sea water at high tide.

NOAA is responsible for depicting on its nautical charts the limits of the 12 nautical mile Territorial Sea, 24 nautical mile Contiguous Zone, and 200 nautical mile Exclusive Economic Zone (EEZ). The outer limit of each of these zones is measured from the U.S. normal baseline, which coincides with the low water line depicted on NOAA charts and includes closing lines across the entrances of legal bays and rivers, consistent with international law. The U.S. baseline and associated maritime limits are reviewed and approved through the interagency U.S. Baseline Committee, which is chaired by the U.S. Department of State. The Committee serves the function of gaining interagency consensus on the proper location of the baseline using the provisions of the 1958 Convention on the Territorial Sea and the Contiguous Zone, to ensure that the seaward extent of U.S. maritime zones do not exceed the breadth that is permitted by international law. In 2002 and in response to mounting requests for digital maritime zones, NOAA launched a project to re-evaluate the U.S. baseline in partnership with other federal agencies via the U.S. Baseline Committee. The focus of the baseline evaluation was NOAA's largest scale, most recent edition nautical charts as well as supplemental source materials for verification of certain charted features. This dataset is a result of the 2002-present initiative and reflects a multi-year iterative project whereby the baseline and associated maritime limits were re-evaluated on a state or regional basis. In addition to the U.S. maritime limits, the U.S. maritime boundaries with opposite or adjacent countries as well as the US/Canada International Boundary (on land and through the Great Lakes) are also included in this dataset. The primary purpose of this dataset is to update the official depiction of these maritime zones and maritime boundaries on NOAA's nautical charts. The limits of these zones are subject to modification, as represented on future charts. The limits shown on the most recent chart edition take precedence.View Dataset on the Gateway

The map shows sailing routes and a table listing the distance, in miles, from Halifax, Montreal and Quebec to major ports. Although Newfoundland and Labrador was not a part of Canada in 1906, there is some data shown for this region. The lighthouses are distinguished between fixed, revolving lights, and light ships. The depth of water in the Great Lakes is indicated by contours and tints of blue. The deeper portions are shown in the darker tints, while lighter tints indicate more shallow waters.

Lake Erie and Lake Saint Clair Bathymetric ContoursImportant Note: This item is in mature support as of March 2025 and will be retired in July 2025.This feature layer, utilizing data from the National Oceanic and Atmospheric Administration (NOAA), displays the bathymetric contouring of Lake Erie and Lake Saint Clair. Bathymetric contouring shows the depths of landforms below sea level. The bathymetric depths are often shown on maps with contour lines. A contour line represents a corresponding imaginary line on the bottom of a water body that has the same elevation or depth along its entire length.Per NOAA, "NOAA was engaged in a program to compile Great Lakes bathymetric data and make them readily available to the public, especially to the communities concerned with Great Lakes science, pollution, coastal erosion, response to climate changes, threats to lake ecosystems, and health of the fishing industry. This program was managed by NCEI and relied on the cooperation of NOAA/Great Lakes Environmental Research Laboratory, NOAA/National Ocean Service, the Canadian Hydrographic Service, other agencies, and academic laboratories."Note: The purpose of this data is for scientific research, commercial exploration, fishing, and policy & decision-making. These data are NOT intended to be used for navigation. Nautical charts produced and certified by NOAA should be used for navigational purposes.

With this update the Canadian Hydrographic Service (CHS) offers both a complete inventory of bathymetric data free to the public for non-navigational as well as, for the first time, a collection of intensity image data products. To meet a growing desire in the scientific, commercial, environmental, and Indigenous communities for backscatter intensity data, the Canadian Hydrographic Service (CHS) has embarked on a Pilot Project to produce and distribute intensity imagery products from our current multibeam echo sounder (MBES) and LiDAR data holdings. MBES and LiDAR sensors collect two types of data, seafloor depth and backscatter intensity. The seafloor depth, or bathymetry is well represented on the CHS NONNA Data Portal. These products are available in a spatial resolution of 10 metres or 100 metres. While typically outside of our primary focus on bathymetry and charting for safe navigation, the CHS recognizes the importance of intensity data for the purposes of environmental and ecosystem management as well as the economic benefits associated with increased understanding of our marine environment. Backscatter intensity data, recorded in decibels (dB) is a measure of the strength of the return of a MBES pulse from the ocean floor to the multibeam receiver. These measures may be visualized as grey scale intensity map imagery. Backscatter intensity imagery can provide researchers with information about the surficial geology of the seafloor or objects on it. For example, hard, rocky materials will reflect more sound energy than softer materials such as mud. To be clear, the CHS is not attempting to create fully normalized and ground-truthed backscatter products. The CHS’s intensity and reflectance data holdings may be best understood as ‘collateral’ data encoded within the raw datagrams collected during MBES & LiDAR bathymetric surveys. NEW CHS NONNA INTENSITY A CHS NONNA Intensity product package is a ZIP file containing either an ASCII (x.y,dB) and/or a GEOTIFF image (w. intensity band) and the available metadata file. Variations in Intensity product resolution and quality are dependent on the contributing source data. TERMS OF USE To directly access the CHS NONNA Data Portal please follow this link - https://data.chs-shc.ca/login (Note: The data portal is NOT compatible with Internet Explorer browser). The Canadian Hydrographic Service (CHS) NONNA Data products are for NON-NAVIGATIONAL USE ONLY. Please see the Open Data Licence below and the CHS NONNA LICENCE viewable on https://data.chs-shc.ca/login and downloadable with the NONNA data, for the full terms and conditions governing the use of this data. ----- PRODUCT DESCRIPTION ----- The « NONNA » refers to the NON-Navigational nature of the data. Intensity data products contain NO depth information and as such are COMPLETELY UNSUITABLE FOR NAVIGATIONAL PURPOSES. The CHS NONNA Intensity Data products are packaged as a ZIP file containing an ASCII and/or GEOTIFF image dataset and a related metadata file. Resolution for data sources varies from data sources to data source and is dependent on the resolution of the source data it was derived from. The Intensity data supplied will be from various survey platforms, using a variety of MBES systems over the full extent of the CHS’s implementation of MBES and LiDAR surveying. All survey data provided will have been collected and processed to CHS data acquisition standards, which is to say these data were COLLECTED FOR THE EXPRESS PURPOSE OF SAFETY OF NAVIGATION and the need to maintain and update sounding data for CHS charts. Best practices for collecting MBES bathymetric data are not necessarily best practices for surveys where the express purpose is the production of intensity data products. As such, the data in our Archives may not have been collected to a standard best suited for producing high quality intensity data products. ----- DATUM ----- All CHS NONNA data sources are horizontally referenced to the World Geodetic System 1984 (WGS84) ESPG4326. CHS NONNA Intensity products contain no depth values and as such require no vertical reference. ----- DATA PRESENTATION ----- CHS NONNA Intensity products adhere to a different naming convention than the CHS NONNA Bathymetric products. Each product name has an unique ID that references the lineage of the contributing hydrographic source. Each contributing source is a hydrographic survey conducted by a single vessel using a single MBES. These products are available to view, query and download via the CHS NONNA Data Portal. The CHS NONNA Intensity products are ZIP files that contain product coverage (at varying resolution). The following formats are available for download: • 32-bit GeoTIFF • ASCII (XYI) These formats can be opened using a wide variety of GIS applications. NOTE: Gaps in the data may be visible where modern surveys have not yet been conducted, the data is not updated to Chart Datum (CD) or where legacy data has not yet been digitized. In addition, there may be data sources removed from the CHS NONNA Data Portal for further processing in the CHS’ Bathymetric Database, and as such, these datasets will not be available until such work is complete. Our investigation has uncovered existing intensity data products in our Archives that will be available for distribution immediately. However, there is a wealth of intensity near to completion. CHS NONNA Intensity products will be published as they become available. Data sources included in the CHS NONNA products may not have been subjected to the same level of quality assurance as those in official navigational products.

The Canadian Ice Service (CIS) produces digital Arctic regional sea ice charts for marine navigation, forecasting, and climate research. The ice charts are created through the manual analysis of in situ, satellite, and aerial reconnaissance data. The ice charts have information on ice concentration, stage of development, and ice form, following World Meteorological Organization terminology. This digital record of sea ice charts begin in 2006 and cover the following regions of the Canadian Arctic: Northern Canadian waters (Western Arctic, Eastern Arctic, and Hudson Bay) and Southern Canadian waters (Great Lakes and East Coast). Each regional shapefile (.shp) (encoded in SIGRID-3 format) and associated metadata file (.xml) are combined into a tar archive file (.tar) for distribution. All data are available via FTP.
