Point Offset screen
If you do not have a
compass, you can use
MobileMapper Pro's
Compass screen (see
also page 40) to deter-
mine the bearing to the
offset feature. If you
have been moving for 5
to 10 seconds along a
straight line, the Com-
pass screen will tell
you your bearing. You
can use this to deter-
mine the bearing to the
offset feature. CAU-
TION! The receiver
cannot determine
direction while station-
ary and the compass
direction remains the
same even if you rotate
the receiver.
Visual estimation for
horz. & vert. distances
is usually good enough
in terms of accuracy.

This displays the Point Offset screen on which you
should enter the following parameters:
Bearing: Compass direction to the feature from your
current position. You need a compass to measure this
angle (see also opposite). To input a value for Bearing,
press ENTER and increment or decrement the high-
lighted number using the up/down arrows. To edit
another digit, use the left/right arrows. When you are
done, press ENTER again. Press the down arrow to
move the cursor to the next field.
Horz. Distance: Horizontal distance to the feature from
your current position. Enter a value for Horz. Distance as
described above for Bearing. When you are done, press
ENTER again.
Vert. Distance: Vertical distance to the feature from your
current position ("0" if the feature and yourself are at
the same elevation -on a flat area). Enter a value for
Vert. Distance as described above for Bearing. When you
are done, press ENTER again.
- Then press ESC to return to the Logging screen. This
writes the offset into memory, but you can edit it later
if you like by going through the same process. If you
close the feature and return to the Map screen, you
will see that the feature is offset from your position in
the middle of the screen.
