Interpolation (continued)
This example on the left shows the interpolated output vs. the sampling depth
increments. If a core was taken and cut into 10 cm depth increments the output file will
show 05 cm thru 95 cm, but the 05 cm data corresponds to the interpolated value using
0-10 cm data, not the data at precisely 05 cm. This continues down the probe until
through the 95 cm measurement. Likewise, in the example on the right a 20 cm depth
increment was used and the output file shows depths from 10 cm thru 90 cm. The 10
cm measurement corresponds to the interpolated data found between 0
– 20 cm. This
continues for every 20 cm increment of soil.
The example on the left illustrates how
the interpolation can use multiple cores
to obtain one value. If the a distance
was equal to 3m and the b distance
equal to 3m, then all three probes would
be interpolated into one to obtain the
value for the 10cm sample. If this is not
desired then make sure that a and b are
less than the actual probe spacing.
