Create New. The eld view will be opened.
3.2 Working a eld
Before starting a work on a eld, or before starting
the measurement of the eld, it is important to set
the working width (the width of the machine you are
using),
1. Go back to the Farmnavigator main menu
2. Press the Farmnavigator Settings button
3. Press the Working Width button
4. Use the left and right arrows to set the desired width
5. Press Accept to conrm
Please read par. 2.3 for the other settings.

14 - AvMap
Farmnavigator
Press Field view. Press the Start Work button in the
bottom bar to start recording the data (worked area,
speed, perimeter and area) that will be saved in the
Fields Database.
To stop the recording of the worked area click stop in the
down left corner. You can start working on this eld again
at any time with a click on start or when you reopen the
eld in the elds’ database.
3.3 Measuring Perimeter and Area
The rst operation you can do is to measure the eld
by driving along the perimeter of the eld. Drive some
meters at rst. Then click the measure button (with
the ruler icon). The boundary now is recorded from the
starting point (red arrow). Now drive around the eld
until you have reached the starting point, and then click
the measure button again. The Field limits are now saved
and the area is calculated. This information is stored in

AvMap - 15
Farmnavigator
the elds’ database.
3.4 Positioning obstacles / soil samples
You can record the positions of soil samples or obstacles,
like trees or holes.
To save a position, go as near as you can to the relevant
object and click the obstacle button (with the orange
cone icon). The positions of obstacles and soil samples
are now saved in the elds’ database and are shown on
the map with an orange cone icon and a progressive
number.
3.5 Setting the Guide lines
Once you have created the eld, you can go on with your
work using the Assisted-Driving function (a.k.a parallel
guidance).
The recording of eld perimeter and the reference line
can be done in one step.

16 - AvMap
Farmnavigator
In order to get driving assistance, you need to set the
guide lines.
1. Open the farm navigation main menu
2. Press the Settings button
3. Press Guide lines.
4. Choose among 4 different types of guide lines pressing
the desired option:
• Parallel
• Contour
• Tram lines
• Round and Round
5. Conrm by pressing the Accept button
6. Press Field view in the upper right corner
3.5.1 Parallel guide lines
Parallel guide lines are ideal for elds with straight
boundaries. When driving the rst reference line, set
the point A at the beginning of the track by pressing the

AvMap - 17
Farmnavigator
A button. The starting point is shown on the map as an
orange square with an ‘A’ on it. Once the point A is set,
the B button will appear. When you reach the headlands
set the point B by pressing the B button. The point B is
displayed on the Map just like Point A. These two points
are used to draw the reference straight line and the
corresponding parallel lines at a distance previously set
as working width.
3.5.2 Contour guide lines
Contour guide lines are used for elds with curved
boundaries. Drive the rst reference line setting the
point A, and then, just before you reach the headlands,
setting the point B. The Farmnavigator will record
each position and draw the exact driven line and the
corresponding parallel lines at the distance previously
set as working width or virtual spray boom width.
3.5.3 Tram lines

18 - AvMap
Farmnavigator
This Option is used to work in elds where tram lines
already have been made (e.g. vineyards). In this mode
Farmnavigator does not guide you but it shows the worked
area and allows using the spray boom virtual control.
3.5.4 Round and Round
Setting the round and round guiding lines you can create
concentric lines starting from the eld’s perimeter
up to the centre. Press A, then start driving along the
perimeter and press B when you have completed it: the
software will draw concentric lines up to the centre of
the eld.
3.6 Assisted driving
After the Guiding lines have been set, the navigation aid
is displayed above the Map. The navigation aid shows
with two directional arrows in which direction the
steering has to be corrected to drive on the calculated

AvMap - 19
Farmnavigator
guiding line. The deviation from vehicle position to
guiding line is shown between the directional arrows in
m and cm to allow very accurate corrections. On the
left side there are four boxes showing: worked area, trip
(distance covered), speed and DOP (precision of GPS).
For info about the DOP, read appendix A. Once the
work is done, press the Stop Work button. The worked
area (highlighted in green) is saved in the eld page in
the Fields Database. You can then open the eld and
continue the work.
3.7 Using the spray boom virtual control
Farmnavigator includes a virtual control of the spray
booms. This function can be used to control sprayers
but also other machines such as spreaders and planters
that work in a similar way. When spreading chemicals
on a eld it is very important to control the treated
area and to avoid treating twice the same portion of

Farmnavigator
terrain. Farmnavigator software will draw your sprayer,
reproducing the exact number of sections and nozzles,
and it will support you to switch the different sections
on and off.
To activate this function press the Spray Boom button in
the main menu and then press the Boom On button.
ATTENTION when the spray boom virtual control is
activated, its settings are used to calculate the working
width, ignoring the width set in the Working Width page
(par. 2.3.1).
Now you can set the number of sections and the width of
each Nozzle using the arrow Buttons.
The Sections are displayed by numbered squares. You can
select each section and change its width by clicking the
modify size button. Use the arrows to adjust the number
of booms and conrm with OK to save the settings and
