Waypoints may also be gathered directly from the Mark
Waypoint Page without using the Averaging function; by
pressing the
ENTER
Key to save. However, the data collected
will have a lower level of accuracy and this method is not
recommended.
Collecting Line Data
Line data is gathered by collecting a waypoint at the start of the
line feature, at each successive turn in the line, and at the end
of the line feature.
Give each waypoint a unique and identifiable name that also
indicates the order in which the point falls. For example, name
the first point 100, the second 101, the third 102 and so on.
Take accurate notes so that your data will be interpretable when
it is taken back to the office.
To calculate the length of a line (Route) in the field:
•
Press
the
MENU
Key twice to open the Main Menu
page.

Press
the
ROCKER
Key to highlight Routes.
•
Press
the

Key to
decline the point and go back to the Waypoints by
Name page.
Repeat this process until you have added all the waypoints that
define the measured line feature.
Once all of the waypoints have been added to the route, the
total route distance will be displayed on the Route Page. Leg
distance between waypoints as well as other route
characteristics can be displayed by highlighting the Route name
(in the top field of the Route Page) and then pressing left or right
with the
ROCKER
Key.

Collecting Polygon Data
Polygon data is gathered the same way as line data, either as
waypoints manually entered and added to a Route or as
automatically generated waypoints along a Track.
To capture a polygon feature using waypoints:
Collect a waypoint at a starting point on the perimeter of the
polygon feature that you will recognize when you return to it.
Collect waypoints at each successive corner of the polygon.
You do not need to re-collect the position of the start point of the
polygon feature.
To capture a polygon feature using tracks:
Set the track recording method in the same way that you would
for collecting a line feature. Turn on track recording at a
recognizable starting point for the polygon and begin navigating
along the area boundary. Turn off track recording when you
return to the start point or when the boundary of the area is a
straight line from where you stand back to the start point.
Creating “Saved Tracks” and calculating areas in the field:
Open the Tracks page, select the Save button and press the
ENTER
Key.
You will be given the choice to save the entire track log or to
save a portion of the log from the most recent track point to one
of the breaks in the log caused by turning track recording on.
Remember, you put these breaks in on purpose by turning track
recording on at the start of a feature and whenever you returned
to the boundary of the feature after making a detour.
Choose one of the break points in the drop down list by
highlighting it with the
ROCKER
Key and then pressing the
ENTER
Key.
Saving that portion of the track log as a track will bring up the
Track Page. The Track Page will display the acreage and
perimeter of the saved track.
NOTES:
Saved Track area may not match that of ArcView for the same
area using the same points; use the GPS area only for
reference in the field.
When using the Backpack GPS Receiver, the location of the
receiver on the backpack is where the GPS data will be
recorded. Try to keep the receiver on the backpack as close to
the location of the point that you want to record. When using just
the Garmin the ‘globe’ on the unit is the receiver.
