Hello,
I have a Land surface temperature (LST) image of coarse spatial resolution (pixel size=1km) and I want to perform a disaggregation in order to enhance the spatial resolution with auxillary data (image of albedo (30m), NDVI (30m)). I tried to look for an algorithm in order to perform that but unfortunately I couldn't find any path to start that.
Best regards,

Well if you can't find the description of those methods then we certainly can't. I've never even heard of them before. Do you just want to upsample your low res image so that it has as many pixels are your high res image?

Hello, yes, this is more or less my aim, the only problem that I might face is that, the pixel values must be correlated btween the target image and the auxillary image ( not all of them obviously), but in the end an upsampling method can be helpful as a first try.
