Somewhere in the margin should be scales for latitude and longitude, similar to
the one for distance. Dividers or a rule are necessary for accurate measurments.
The scale for latitude is somewhat redundant since one minute of latitude is
equal to 1 nautical mile, right?

I plan on eventually getting a gps, but I was wondering how one gets
lat/long coordinates that are precise enough to use. I was looking at
some old charts I have (5 years old is the latest one) and the markings
on the borders are quite coarse. They leave a lot of latitude for error.
(sorry; couldn't resist). Do I have to interpolate to be more precise?
This of course would be for planning my course beforehand.
