Andrew,

One thing your researchers should keep in mind is the so-called "Coastline Paradox" (Google it), which can mean, among other things, that if the numbers you find weren't derived/calculated using the same process (and scale of measurement tool), you'll end up with numbers that can't be fairly compared (assuming that's part of the plan).

I don't imagine this would be a problem for, say, the prairie provinces, but for the rest (esp. Nunavut and NWT), and for any Mexican state whose boundary isn't composed largely of straight lines, this could make for an awfully big fly in the ointment.

Anyway, I'll look for numbers. Nothing useful from NRCan?

Hi folks,

I have some researchers who would like to look up the length of individual provincial borders and shorelines in Canada. I found the numbers for Canada's borders, but nothing for the individual provinces and territories.

These researchers are also not GIS students or professionals, so some online resources which had these numbers listed somewhere would be perfect.

Any ideas? Your suggestions are welcome.

Thanks,

Andrew

PS: They are also interested in the length of borders of Mexican states.
