Coastal British Columbia bathymetry. Depth P - Photic 0-20m S - Shallow 20-200m M - Midepth 200 - 500 D - Deep 500-1000m A - Abyssal > 1000m X - unknown Blanks are land CRIMS is a legacy dataset of BC coastal resource data that was acquired in a systematic and synoptic manner from 1979 and was intermittently updated throughout the years. Resource information was collected in nine study areas using a peer-reviewed provincial Resource Information Standards Committee consisting of DFO Fishery Officers, First Nations, and other subject matter experts. There are currently no plans to update this legacy data.

The Atlas of Canada's Relief Map shows Canada's relief with a colour ramp of elevation ranges. Colour tints of depth ranges show ocean bathymetry. This map shows the relief of Canada using three different resolutions. Starting with low resolution, as you zoom in, it transitions to medium and then high resolution. The low resolution is derived from the merging of Natural Resources Canada (NRCan) High Resolution Digital Elevation Model (HRDEM) from 2021 and the legacy Canadian Digital Elevation Model (CDEM), 1945-2011, resampled to 804 metres. The medium resolution is the NRCan, Medium Resolution Digital Elevation Model (MRDEM) from 2024, with modifications by the Atlas of Canada for cartographic purposes. The high resolution is NRCan's 2021 HRDEM product with 1 metre pixels. Also included, is a bathymetric layer from GEBCO 2021 (https://download.gebco.net/) resampled to 804 metre pixels.

The joint Natural Resources Canada/Department of Fisheries and Oceans Marine Spatial Planning Program requires the highest resolution marine based bathymetric elevation data and adjacent land based topographic elevation data that are available. This digital elevation model of Canada's west coast compiles the best data available from multiple government agencies to create a regional model gridded at 10 meter spacing. The transitions between the marine and terrestrial areas are seamless creating a continuous surface of elevations for scientific research and mapping.
