Hi Guys, Thanks for the help. Mike Smolen suggested http://www.ngdc.noaa.gov/mgg/global/seltopo.html, an excellent worldwide site ("look Mum, I can see my house from here..."). In my further searches I found http://students.washington.edu/dfinlays/pugetsound/ - this has DEM and bathymetry data in GRD format for the Puget Sound, up to Anacartes and Vancouver Island and across the Olympics to the Cascades (with only two gaps in bathymetry) - excellent resource for those of us working locally. What did we all do before the Internet? Or am I just showing that I am over 30!?! Regards & Thanks Again: GREG... ------------------------------------------ Greg Cocks wrote: > Hi List, > > I am looking for detailed bathymetry data, Canadian border to > Bellingham, Washington State, USA. > > Can anyone suggest a possible source or somewhere else I can start > looking for this data electronically?
