14. Grids
14.1 Grids Overview
Grids consist of a group of square-shaped
AOIs in a large square/grid formation. They
allow you to overlay a square grid/table onto
the map. Grids are used to split an area into
searchable chunks. For example, search
and rescue teams can use grids for rescue
missions. Other examples of uses include
ornithology (bird watching), archaeology,
forestry, crime surveying, etc.
Each grid consists of 100 AOIs (or squares),
i.e. 10 across and 10 down. Each AOI is
300m x 300m. The grid follows a default
naming convention and individual AOIs can
be renamed individually (section 17.05). As
you zoom into the map, the name of the AOI
appears in each square. Moving the locator
circle over individual squares shows the name
of the AOI in the top right-hand corner.
Rows are labelled AA, AB, AC, etc... and
columns are labelled 1, 2, 3, etc... so a square
or individual AOI can be referred to as “AA3” or
“AB2”. (To avoid confusion with the number 1,
the letter 'I' has been omitted).
You are able to change the colour and pattern
of individual AOIs just like a regular AOI. The
grid appears on the PLANNING screen once
created. More than one grid can be placed on
the map. Visibility can only be set for individual
AOIs, not for the entire grid.
14.2 Add Grid Screen
(GPS MAP → MAIN MENU → OOI Menu →
Add Grid by Map)
To create a grid, select Add Grid by Map from
the OOI Menu and press Select or centre
press the joystick. This will take you to the Add
Grid screen where you will need to set the
centre point of the grid.
The orange locator circle has a red cross in the
centre to indicate you are in edit mode and on
the Add Grid screen. Use the top left '+' button
or centre press the joystick to set the centre
point. This will take you to the keypad to name
your grid.
Note: The lower left 'x' button is not used on
this screen.
