public class ArrayResampler extends net.simplace.sim.model.FWSimComponent
Resamples array values from one resolution to another resolution

The resolutions of original dataset and resampled datasets are determined by the arrays iOriginalDepths ($D_o$) and iResampledDepths ($D_r$) which contains the depths of the layers' bottom. The values have to be unique and sorted ascending. ($D_o(i_1) <span class="invalid-tag">Ungültige Eingabe: "<"</span> D_o(i_2) \text{ when } i_1 <span class="invalid-tag">Ungültige Eingabe: "<"</span> i_2$)

The array of values iOriginalValues ($V_o$) must have same length as the iOriginalDepths array. Values are resampled to the new resolution and output to the array ResampledValues ($V_r$) which has same length as iResampledDepths array.

When we denote the overlap of layer $i$ of original dataset and layer $j$ of resampled dataset by $o(i,j)$ and the thickness of layers is by $t_o(i)$ resp. $t_r(j)$, then:

\[ \begin{eqnarray} t_o(i) Ungültige Eingabe: "&" = Ungültige Eingabe: "&" D_o[i] - D_o[i-1] \\ t_r(j) Ungültige Eingabe: "&" = Ungültige Eingabe: "&" D_r[j] - D_r[j-1] \\ o(i,j) Ungültige Eingabe: "&" = Ungültige Eingabe: "&" max(0, \quad min(D_o[i], D_r[j]) - max(D_o[i-1], D_r[j-i]) \end{eqnarray} \]

If cIsProportional is false (the default), the values from those layers $i$, that overlap with the new layer $j$ are summed up, weighted by the proportion of the overlap to the original layer thickness:

\[ \begin{eqnarray} V_r(j) Ungültige Eingabe: "&"=Ungültige Eingabe: "&" \sum_{i} V_o(i) \frac{o(i,j)}{t_o(i)} \end{eqnarray} \]

If cIsProportional is true, then the values from those layers $i$, that overlap with the new layer $j$ are converted to absolute values by multiplying with the overlap $o(i,j)$, summed up and then divided by the resampled layer thickness $t_r(j)$ to get relative values:

\[ \begin{eqnarray} V_r(j) Ungültige Eingabe: "&"=Ungültige Eingabe: "&" \frac{\sum_{i} V_o(i) o(i,j)}{t_r(j)} \end{eqnarray} \]

Specifying resampling mode explicitely

By setting cResamplingMode one can specify explicitely which method to use. cIsProportionalValue is then ignored.

  • AVG - takes the weighted average (corresponds to cIsProportionalValue true).
  • SUM - takes the weighted sum (corresponds to cIsProportionalValue false).
  • FIRST - takes the value from the first (upper) matching layer.
  • CENTER - takes the value from the source layer matching the midpoint of the target layer.
  • LAST - takes the value from the last (lower) matching layer.
