on the map. It then shows the present position as distance on the map
from that reference point.
For example, if it shows a distance of UP 4.00" and LEFT 0.50", you
then measure up four inches and to the left a half-inch from the refer-
ence point on the map to find your location.
To configure a map fix:
To use this format, you need to follow these steps in order. First, take
your map of the area and determine a reference latitude/longitude.
(Note: in order for this system to work, the latitude/longitude lines must
be parallel with the edge of the map. USGS maps are parallel, others
may not be. Also, this works better with smaller scale maps.) The refer-
ence position can be anywhere on the map, but the closer it is to your
location, the smaller the numbers will be that you'll have to deal with.
Once you've decided on a reference position, you can save it as a waypoint.
See the waypoint section for information on saving a waypoint. Save the
reference position as a waypoint. Exit from the waypoint screens.
