Can anyone point me to a dataset (shapefile or other format) for the North American Continental Divide?
I'm looking for a more detailed dataset than the 1:2,000,000 shapefile available from the National Atlas, preferably one suitable for use at 1:24,000.
This is a cross-border task. I already have this data for Ontario, Canada but I also need to complete the model for a large lake that is essentially split in half between the two countries. ...
