The raster datasets to be merged.
|Mosaic Dataset; Raster Dataset; Raster Layer|
The raster to which the input rasters will be added. This raster dataset must already exist. By default, the target raster is considered the first raster in the list of input raster datasets. You can create an empty raster using the Create Raster Dataset tool.
Specifies the method that will be used to mosaic overlapping areas.
Mosaic Colormap Mode
Specifies the method that will be used to choose which color map from the input rasters will be applied to the mosaic output.
Ignore Background Value
Use this option to remove the unwanted values created around the raster data. The value specified will be distinguished from other valuable data in the raster dataset. For example, a value of zero along the raster dataset's borders will be distinguished from zero values in the raster dataset.
The pixel value specified will be set to NoData in the output raster dataset.
For file-based rasters and geodatabase rasters, the Ignore Background Value must be set to the same value as NoData for the background value to be ignored. Enterprise geodatabase rasters will work without this extra step.
All the pixels with the specified value will be set to NoData in the output raster dataset.
Convert 1 bit data to 8 bit
Choose whether the input 1-bit raster dataset will be converted to an 8-bit raster dataset. In this conversion, the value 1 in the input raster dataset will be changed to 255 in the output raster dataset. This is useful when importing a 1-bit raster dataset to a geodatabase. One-bit raster datasets have 8-bit pyramid layers when stored in a file system, but in a geodatabase, 1-bit raster datasets can only have 1-bit pyramid layers, which makes the display unpleasant. By converting the data to 8 bit in a geodatabase, the pyramid layers are built as 8 bit instead of 1 bit, resulting in a proper raster dataset in the display.
When mosaicking occurs, the target and the source pixels do not always line up exactly. When there is a misalignment of pixels, you need to decide whether to resample or shift the data. The mosaicking tolerance controls whether resampling of the pixels will occur or the pixels will be shifted.
If the difference in pixel alignment (of the incoming dataset and the target dataset) is greater than the tolerance, resampling will occur. If the difference in pixel alignment (of the incoming dataset and the target dataset) is less than the tolerance, resampling will not occur and a shift will be performed.
The unit of tolerance is a pixel with a valid value range of 0 to 0.5. A tolerance of 0.5 will guarantee a shift occurs. A tolerance of zero guarantees resampling will occur if there is a misalignment in pixels.
For example, the source and target pixels have a misalignment of 0.25. If the mosaicking tolerance is set to 0.2, resampling will occur since the pixel misalignment is greater than the tolerance. If the mosaicking tolerance is set to 0.3, the pixels will be shifted.
Color Matching Method
Specifies the color matching method to be applied to the rasters.
