Station Interval
As the Smart Cart moves, the odometer triggers the system to collect a data trace at
fixed distance intervals. This interval is called the “station interval”.
The station interval can be changed to allow a longer or shorter distance between
traces. For a successful survey, it is important that several traces be collected over a
target. If the target is small, the user may want to shorten the station interval to ensure
that data traces are collected over the target. Conversely, if the target is very large or is
a flat-lying feature it is probably not necessary to collect a lot of traces over the target, in
fact, sometimes this can make the target more difficult to see in the data. In this case it
may be beneficial to increase the station interval.
Figure 5-8: The Station Interval is the distance between sample points on the ground. Be careful
not to choose a Station Interval that is larger than the smallest target to be detected.
