The receiver determines the perimeter of an area feature
by estimating the distance between successive points on
the line feature with the assumption that each point is on
a sphere of average Earth radius. The elevations of the
points are not factored into the equation. Thus the
receiver calculates the spherical distance rather than the
horizontal or slope distance between the successive posi-
tions. The perimeter of the area feature is the sum of all
these distances. For the same reason, the measured area
is that of a curved, not flat, feature.
5. Pausing a Feature
When you are recording lines or areas, it is sometimes
impossible to walk or drive the entire length of the feature
because of obstacles in your way such as fences, build-
ings, bodies of water, etc. When you must interrupt the
recording of any feature (excluding point features), follow
these steps:
-
Press MENU, highlight
Pause <feature name>
and press
ENTER. This pauses the logging of the feature.
-
Move around the obstacle to the next accessible por-
tion of the feature
-
To resume logging, press MENU, highlight
Resume
<feature name>
and press ENTER. This resumes the log-
ging.
-
When you finish logging the feature, just press MENU
and select the
Close <feature name>
option.
