# 3.4.3.10. Mosaic band sets¶

Mosaic band sets

This tool allows for the mosaic of band sets, merging the corresponding bands of two or more band sets defined in the Band set. An output band is created for every corresponding set of bands in the band sets.

NoData values of one band set are replaced by the values of the other band sets.

## 3.4.3.10.1. Mosaic of band sets¶

• Band set list : list if band sets defined in the Band set; in case of overlapping images, the pixel values of the first band set in the list are assigned.
• Use value as NoData : if checked, set the value of NoData pixels, ignored during the calculation;
• Create virtual raster output : if checked, output is created as virtual raster .vrt composed of as many .tif files as the number of threads defined in System; for large rasters this can speed up the process;
• Output name prefix : set the prefix for output file names (default is mosaic);
• BATCH : add this function to the Batch;
• RUN : select an output directory and start the mosaic process;
