Canadian Hydrographic Service Non-Navigational (NONNA-100) Bathymetric Data
The Canadian Hydrographic Service (CHS) NONNA-100 Bathymetric Data products are non-navigational 100m resolution bathymetric products.
« NONNA » refers to NON-NAvigational
« 100 » refers to the approximate resolution (metres) of the products
The CHS NONNA-100 Bathymetric Data products represent all currently validated, digital bathymetric sources acquired by CHS, combined at a resolution of approximately 100 metres. This bathymetry is available for download in both 32-bit GeoTIFF and XYZ formats. Additionally, the data can be accessed and viewed using ArcGIS or Google Earth, among others. There are detailed instructions available below which show the varying ways to view, access and download this data.
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)
The Arctic CHS NONNA-100 datasets north of 80 degrees are currently under construction. An update will be provided once these products are complete.
There are various valid vertical datums associated with CHS' bathymetric sources. As a result, the vertical reference of the CHS NONNA-100 has not been adjusted to a unified vertical datum.
There may be data visible on land. These are elevations that were acquired during LiDAR surveys. The values will appear as a positive number when querying the data.
For bathymetry in non-Canadian waters, please consult the appropriate Hydrographic Office.
