6 Using Mapping/Recording in theField
6.1 Automatic mapping
The system supports the automatic control of map recording. You can control under
what conditions maps are recorded by selecting from a number of pre-configured
rules. The availability of a particular rule may depend on machine type and sensor
configuration. For more information, see your site supervisor.
6.1.1 Fixed mapping rules
The following conditions must always be satisfied, and are not configurable:
l Mapping must be turned on, and a design or map loaded and at least one
mapping type enabled.
l The system must be receiving high accuracy positions.
l The machine must have moved at least 0.25 m (10 inches) since the last map
update.
l The machine must have moved less than 10 m (33 ft) since the last map update.
6.1.2 Machine mapping rules
The following mapping types can be subject to automatic mapping control:
l Pass Count
l Terrain
l Radio
l Cut/Fill
The following conditions can be combined to control mapping:
l Minimum height – this condition is satisfied when the elevation of a cell on the
current pass is less than the elevation of the same cell on any previous pass.
l Bucket tip – this condition is satisfied when a condition, selected from the
following list, is satisfied:
Driving forwards – this condition is satisfied when the machine is moving
forwards.
Always – this condition is always deemed to be satisfied.
