You are still able to use the Mosaic tool even if the raster datasets have different color maps however, you must choose the proper color map mode.
When mosaicking with raster datasets containing color maps, it is important to note differences across the color maps for each raster dataset you choose to mosaic. File geodatabase rasters and ArcSDE rasters will work without this extra step. The pixel type will be the same as the target raster dataset.įor file-based rasters and personal geodatabase rasters, the Ignore Background Value must be set to the same value as NoData in order for the background value to be ignored. Whenever possible, use the Last Mosaic Operator to mosaic raster datasets to an existing raster dataset in a file geodatabase or ArcSDE geodatabase it is by far the most effective way to mosaic. The Blend and Mean Mosaic Operator options are best suited for continuous data. The Target layer is considered the first raster in the list of Input Rasters.įor mosaicking of discrete data, First, Minimum, or Maximum Mosaic Operator options will provide the most meaningful results.
For example, you can keep the color map of the last raster dataset used in the mosaic.

There are also several options to determine how to handle a color map, if the raster dataset uses one. The overlapping areas of the mosaic can be handled in several ways for example, you can set the tool to keep only the first raster dataset's data, or you can blend the overlapping cell values. Some mosaic techniques can help minimize the abrupt changes along the boundaries of the overlapping rasters. Mosaic is useful when two or more adjacent raster datasets need to be merged into one entity. The target raster must be an existing raster dataset, which can be an empty raster dataset or one already containing data.
