Tools that honor the Cell Alignment environment will adjust the cell alignment of the output to match the cell alignment of the specified processing extent.
Usage notes
- If an extent is specified in the Snap Raster environment, it will override the extent specified in the Cell Alignment environment.
- The Align with Input option preserves the cell alignment of the input and does not resample the data.
- The Align with Processing Extent option will resample the input raster using the resampling method specified in the environment setting.
Dialog syntax
- Default—The cell alignment will follow the default behavior of the tool. This is the default.
- Align with Processing Extent—The extent of the output cells will be adjusted to match the cell alignment of the specified processing extent.
- Align with Input—The output cells will follow the alignment of the input.
