Raster Mosaic
Function Description
Two or more Raster Datasets are combined into one Raster Dataset with GCS as reference.
Examples of each of the two Raster Datasets Mosaic are shown below.

- Toolbox-> Data Processing-> Grid-> Algebraic Operation
Parameter Description
- No value: The no-value attribute of the Raster Dataset, indicating that the position where this value is filled in the Raster Dataset is an invalid value. The default value is -9999. You can also enter a no-value value by yourself.
- No Value Tolerance: The tolerance of the specified No Value numeric value, regardless of the original No Value in the grid.
- Resolution: The cell size of the Result Dataset. The default value is 0, which means that the minimum resolution in all Input Data: sets will be used as the Result Raster resolution.
- Overlapping area value: The value mode of the overlapping area during mosaic. The default value is "the value of the first Dataset", that is, the overlapping area will keep the value of the first Dataset during mosaic. In addition to this, you can also select "Value of last Dataset", "Max of all the datasets", "Min of all the datasets", "Mean of all the datasets".
- Result Pixel Format: Pixel format of the result Raster Data.
Caution: - Pixel Format does not support single precision and Double
- when tessellating an Image Dataset.
- Note that the grids to be tessellated must have the same coordinate system and must have the same number of bands.
