I am looking for free Bathymetric contour data in shapefile format for depths between 0-200 meters for North America (including Canada, especially Vancouver, BC). I prefer contours at 10 meter increments, but will take whatever I can get.
I have found Bathymetric layers for 0 and 200 meters from http://www.naturalearthdata.com/downloads/10m-physical-vectors/. However, I need more detail within that range.
My questions are:
- Where can I find freely available Bathymetric data between 0-200 meters for North America?
- How did you find the data and what did you use to search for it?
