The following information specifies how the cells in raster datasets are assigned values under various conditions when using the Polyline to Raster tool.
The two ways to control how the cell will be assigned a value when more than one feature falls within a cell are described below.
Maximum length
When the Cell assignment type parameter is set to the Maximum length option, do the following:
- If there is only one line in the cell, select that line.
- If there is more than one line in the cell, the following apply:
- If there are no priorities set or the priorities are the same, select the one with the lowest Feature ID (FID).
- The feature with the largest positive priority is automatically selected for conversion regardless of the length.
- If the feature lies on a cell boundary, the boundary rules apply.
Maximum combined length
When the Cell assignment type parameter is set to the Maximum combined length option, do the following:
Note:
For this description, the combined feature is considered to be a single feature with the FID equal to the lowest of the combined features and the priority equal to the highest of the combined features.
- If there is only one line in the cell, select that line.
- If there is more than one line in the cell, the following apply:
- If there are no priorities set or the priorities are the same, select the one with the lowest FID.
- The feature with the largest positive priority is automatically selected for conversion regardless of the length.
- If the feature lies on a cell boundary, the boundary rules apply.
