Menu Geometry > Homologous points extraction
Fix image : PAN
Moving image : XS
Select homologous points in the bottom windows
➢Add / Evaluate / Guess
=> Output : XS image at the same size and resolution than the panchromatic one. Images fusion is now possible.
Use case 12 : Superimpose two images with homologous points

Pan-sharpen an image
➢Requires Panchromatic and Multispectral input images at the same
resolution
Menu Filtering > Pan-sharpen an image
➢Enter PAN and XS image well registeredOrtho-images of PAN + ortho-image of XS
