- Navigate to the next grid point: When you have fin-
ished recording the first point feature, tap Done. A
message prompts you to go to the next grid point. Tap
Yes to navigate to the next grid waypoint and record
the next point feature within the grid. This takes you to
the Map screen where you can see your current posi

tion marked by the arrow and the next grid waypoint
highlighted with a “crossed box” target symbol. Small
hollow squares indicate the locations of all the unvis

see your heading indicated by the direction of the
arrow marking your position. Adjust your movement as

Each grid point is a geographic coordinate you should
make every effort to occupy so that the data you record
is evenly spaced and complete. However, each grid
point is merely an aid for navigating to the ideal loca

you record is ascribed to the position of the ProMark3
receiver and NOT to the grid point.
It is also possible to navi-
gate to any grid point (or
any location for that mat-
ter) on the Map screen by
tapping over another grid
point. After you record data
at this location, you will
still be prompted to go to
the next grid point .
