I have DMSP/OLS and VIIRS satellite images. For the 1st image the bit depth is 8, for the 2nd image is 32. I want to make intercalibration between those images. Will it cause a problem due to difference in the bit of the images?
No significant issues with it. DMSP/OLS is less accurate than VIIRS, but that will only impact the accuracy of the correlation, not the overall intercalibration.
