Start | Index | Overview • PREV | UP | NEXT 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. ($D_o(i_1) < D_o(i_2) \text{ when } i_1 < i_2$)
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:
\[ \begin{eqnarray} t_o(i) & = & D_o[i] - D_o[i-1] \\ t_r(j) & = & D_r[j] - D_r[j-1] \\ o(i,j) & = & max(0, \quad min(D_o[i], D_r[j]) - max(D_o[i-1], D_r[j-i]) \end{eqnarray} \]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:
\[ \begin{eqnarray} V_r(j) &=& \sum_{i} V_o(i) \frac{o(i,j)}{t_o(i)} \end{eqnarray} \]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:
\[ \begin{eqnarray} V_r(j) &=& \frac{\sum_{i} V_o(i) o(i,j)}{t_r(j)} \end{eqnarray} \]| Content Type | Name | Description | Data Type | Unit | Min Value | Max Value | Default Value |
