There are four different types of features:
- Point feature: This feature can be described as a point,
geometrically speaking. Field operators should log point
features in static mode, i.e. they are supposed to stay sta-
tionary at these points for at least one second.
- Line feature: This feature can be described as a line.
Field operators should log line features in kinematic
mode, i.e. they should start logging this type of feature at
the beginning of the line, move along this line and stop
logging when reaching the end of the line.
- Area feature: This feature can be described as an area.
Field operators can log area features either in kinematic
mode (general case) or in “multi-static” mode in case of
areas with regular (straight) contours.
- Grid feature: This feature defines an array of evenly
distributed waypoints where field operators record obser-
vations or make measurements using some instrument.
In-depth information on grid features is given on page
86.
There are three different types of attributes:
- Menu style: the attribute value can only be one of the
preset values from a user-defined menu
- Numeric style: the attribute value can only be within a
pre-defined range of numeric values
- Text style: the attribute value is in text form and should
not exceed the permitted length (20 characters).
