Excellent points, but also note that for latitude and longitude, there
are two other routes available. If you can read a topographic map you
can download those maps from
http://www.calgarymountainclub.com/home.php?page=maps .

Or beg, borrow or steal a GPS unit (of late I have taken an interest
in Open Street Map, so I bought a $20 Microsoft GPS receiver from
Factory Direct (yes the receiver is well supported under Linux :-)
)... That is another way to get accurate numbers...
