Revisiting and Updating Existing GPS/GIS Jobs
You can use MobileMapper not only to position and de-
scribe new GIS features but also to update information gath-
ered previously. This is particularly useful when collecting
data on things that change over time: streetlight bulbs burn
out, new roads are added to housing developments, new
crops are planted, etc.
1. General Procedure
After you have arrived in the area of the job to be reviewed,
after you have turned on MobileMapper and made sure it
calculates your position, follow the procedure below to re-
visit and update this job.
- Press the LOG button, select the
Open Existing Job option
and press ENTER. MobileMapper lists all the jobs
present in its memory.
- Press the down arrow to highlight the name of the job
you want to update and press ENTER. MobileMapper
displays the navigation screen that was last used.
- Unless this screen is already displayed, press NAV
repeatedly until the Map screen is displayed. From this
screen, you will now indicate the first feature you want
to revisit. If necessary, press the IN or OUT button to
adjust the scale so you can see this feature.
- Press any arrow key to switch to the cursor mode on the
Map screen and then use the arrow keys to move the cur-
sor over the feature you want to revisit first. It’s a good
idea to keep the Map info visible on the screen as it tells
you exactly when the feature is selected. (The feature
name appears in the lower part of the screen when the
cursor is positioned over the feature.)
- When this happens, press ENTER. The Selected screen
is now displayed showing the attribute values currently
ascribed to the feature. Note that the
Goto field is high-
lighted at the bottom of the screen.

Note that you are not
prompted to select a fea-
ture library when you
select an existing job.
This is because the
library that was selected
when the job was created
is necessarily the one
that must be used for the
job when re-opening this
