Glossary

Active Leg The segment of a route currently being used

to compute navigational information.

Bearing The compass direction from your position

to a destination, measured to the nearest

degree.

Coordinates A unique numeric or alphanumeric

description of position.

Datum Refers to the theoretical mathematical

model of the earth’s sea level surface. Map

makers may use a different model from

which to chart their maps, so position

coordinates will differ from one datum to

another. The datum for the map you are

using can be found in the legend of the

map. If you are unsure as to which datum

to use, use WGS84.

Elevation Distance above mean sea level.

GOTO A single leg route with the present position

being the start of the route and a defined

landmark as the destination. (If the unit has

been moved while turned off and has not

yet acquired a new position fix, the start of

the GOTO will be the position fix last

recorded.)

Heading The compass direction in which the

Magellan GPS 310 is moving.
