Selecting the
Pause Road option
Nesting is particularly
useful when you are
mapping things such
as a road with street-
lamps along the route
or a shoreline with
stretches of erosion
along it and the loca-
tions of certain habi-
tats.

You can select the level of detail you want in your line fea-
ture by setting the logging interval. For this exercise,
select the logging interval By Time. Then make set the
interval to 5 seconds.
Then walk for about 30 m (or 100 feet) in any direction.
- Pausing the logging of a feature
Now you will pause the logging of a feature. Just press the
MENU button while you are on the Feature Logging
screen, select the Pause Road option and press ENTER.
Pausing the logging allows you to move around obstacles
without logging positions that are not part of the feature.
It also allows you to "nest" one feature within another (see
below).
- Nesting a feature
When you are logging GPS positions to a feature, in the
current case a road, you may find another feature that you
also want to log. Rather than record the entire road and
come back to record this other feature, you can simply
pause the road feature, as you have done, record the other
feature, close it and resume logging the road. Recording
one feature while you have paused another feature is
called "nesting." You can nest any feature - point, line or
area - into any line or area feature. (It doesn't make sense
to nest a feature into a point feature.)
Now that you have paused the road feature, you are free to
move to any position to record the nested feature, but you
should remember to return to the spot where you paused
the road feature so as to prevent "jumps" in the map of
the road.
For this exercise, you will nest a streetlight. Once you are
positioned next to the imaginary (or real) streetlight, press
MENU, select the Nest Feature option and press ENTER.
The receiver will prompt you to select the type of feature
you want to nest. Select Str Light and describe it with the
feature library just as you did before.
