The Merge Rasters function groups or merges a collection of rasters.
Use this function when you have multiple rasters that you want treated as a single item, such as calculating the same statistics for all images, or when color balancing so you don't need to color balance each image separately. This is useful when working with imagery stored as separate tiles; this way, the tiles are treated as part of the same image.
You can also use this function to combine multidimensional raster datasets spatially or across variables and dimensions.
This function can be used to create a merged multidimensional raster layer from a list of multidimensional rasters. For example, if you have a mosaic dataset that contains 30 years of monthly precipitation data and another dataset with 10 years of monthly temperature data, you can combine them into a multidimensional raster with both variables.
This function can be used to treat items in a mosaic dataset as a single item. The Merge Mosaic Dataset Items tool uses this function to merge items in a mosaic dataset.
To remove this function from a mosaic dataset, use the Split Mosaic Dataset Items tool.
The input raster datasets or multidimensional raster datasets to merge.
Resolve Overlap Method
Specifies the method that will be used to resolve overlapping pixels in the combined datasets.
