Canada west coast topo-bathymetric digital elevation model

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.

Purpose
There are several purposes for this dataset. It is to provide a detailed and clean elevation surface for mapping at many scales from the entire Canadian west coast to large scale localities. It is to be used for scientific research including seafloor mapping, coastal hazards, and habitat identification. It can be used as a basic mapping tool to assist in spatial management planning in the coastal and marine environments.

Description

Title: Compilation, normalization, and merging of datasets comprising the Canada west coast digital elevation model -- Description: 1. The data were downloaded and compiled from original data sources in their original formats and resolutions.

2. All processing of the data were performed in ArcGIS 10.7

3. All data were projected into a common map projection, in this case a NAD83 BC Albers with a central meridian of -126, the standard projection of the BC Government.

4. All data were up sampled or down sampled to a common resolution of 10 meters using appropriate resampling algorithms.

5. Where necessary, data elevations were re-calculated to the vertical chart datum used by the Canadian Hydrographic Service.

6. Data were merged into a continuous elevation surface.

7. The elevation surface was hillshaded using ArcGIS to create a shaded relief layer.

8. A source map was compiled from the vectorized polygons of the original data extents.

9. Metadata were compiled using the NRCan LCNP online metadata editor.
