Merge products combine the advantages of high resolution and multispectral satellite data
and provide a unique basis for visual interpretation on cadastral level.
Merges are processed from simultaneously acquired PAN and LISS-III data.
The processing includes an automated LISS-III to PAN registration, the calculation of a
synthetic blue band and the actual merging using the PCI Pansharp algorithm.
The automatically computed Merge has the same geometric properties as the used PAN product.
You can choose between a natural colour (bands 3, 2, synthetic blue) or
colour infrared (bands 4, 3, 2) Merge.
