On-line map site that can indicate magnetic north on any given map?

July 5, 2006 4:20 PM

Is there an easy-to-use, on-line mapping site that can optionally indicate magnetic north on large-scale map images?

I'm aware of more general solutions such as these:

http://www.ngdc.noaa.gov/seg/geomag/jsp/Declination.jsp

Thanks.

Thanks, rlef98. That looks great for in-browser images. (Now that I think of it -- For big, reasonably-priced, water-resistant printouts that include magnetic declination, I can recommend mytopo.com.)
