12.3.3.3 Station Interval
As Smart Systems 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:  12-9  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.
Note that decreasing the station interval increases the data volume and increasing the station
interval reduces the data volume.
