Maps can act as precious
time-bridges
between sampling or sensing on the one
hand and machine operations on the other hand. These time-bridges are essential or
useful with soil- or crop properties that have a low temporal resolution, thus remain
constant over a rather long time. Prime examples for this are topography, texture,
organic matter and pH of the soil.
However, there are also soil- or crop properties that vary rather fast over time,
thus have a high temporal resolution. Examples for this are water and nitrate in
the soil or some crop properties. The temporal variance in these cases may in fact
be more important than the spatial variance (McBratney and Whelan
1999
), and
consequently maps should then be viewed and used with caution.
