The Logging screen is now displayed where you can
see the list of attributes pertaining to this feature. You
will now enter the “Description” phase of the feature
- With the first attribute highlighted, press ENTER and
choose the right attribute value describing the feature
near you and press ENTER. This takes you back to
the Logging screen.
- Highlight the next attribute in the list and repeat the
previous step. Repeat this step until all the attributes
have been properly described.
“Describing” the feature only takes a few seconds.
By the time you are done with the feature description,
the feature’s GPS position will probably have been
saved in the job. You can also stay more time on the
feature to let the receiver determine several positions.
This will give an even more accurate position for the
feature as MobileMapper will average all the GPS
positions it has computed on the feature.
- To stop logging the feature, on the Logging screen,
use the down arrow to highlight the Close field and
press ENTER. This takes you back to the Feature List
screen
- Move to the next feature and resume the above
instructions to log this feature.
3. Logging and Describing a Line Feature
Basically, you use the same procedure as when you log a
point feature (see 2. above). There are however two dif-
ferences when you log a line feature:
- You need to define a logging interval when you start
logging the feature
- And then you are supposed to move from the begin-
ning to the end of the line feature before stopping the
logging.
These differences are explained below.

The Logging screen also
displays the time elapsed
since you started log-
ging at this point fea-
ture, the number of
satellites currently
received and the current
value of PDOP (see also
page 22).
If you start logging a new
feature and you realize
you this is a mistake, then
you can delete the new
feature being logged by
pressing MENU and
selecting Delete <fea-
ture name>.
Deleting features only
applies to new features
being logged, not to fea-
tures already logged.
