Coherencemap classify

Can you please recommend me some method to classify an interferogram coherence map. I want to create classes like urban area, forest, water…etc like polarimetry but from the interferogram’s coherence map. I tried the snap unsupervised classifiing fuction, but it need polarimetric product for input. Thanks

you could classify any coherence map according to the coherence’s values, so I’d prefer to divide the categories of your map into to three types, 0 - 3, 3.5 - 6.5, 7-10, and according to these values you could divide the objects in your interferogram, of course built up area will have the highest and the soil or unstable area during the time period of your interferogram will get the low values and so on so for, also you could take a look on this,
