SAR IMAGES: AVDVANTAGES AND DRAWBACKS01 INTRODUCTION
� Advantages: you program, you get it!� All Weather + Day and Night
� Drawbacks: it is hard to use! (radically distinct from optical)
� Need of specialised training� Specialised SW� SAR Images present distinct spectral and radiometric characteristics from optical
data, so a different analysis is required. We see different things!

data, so a different analysis is required. We see different things!
Cannot replace optical imagery photointerpretation performance, but it can be the only choice!Caveat: Wrong expectations, prejudices and lack of training or processing infrastructure can make optical analysts reluctant to use SAR imagery and yield project failure. A new mindset is needed

when the area is previously known and we focus on changes.
Only in exceptional cases, when optical data is not available, the analysis of an area can be based only on SAR images.
Pair of images is used for change detection. Can use radar phase!
Set of images are used for temporal analysis of changes.

SUPER RESOLUTION IMAGES ADVANTAGES
� Advantages : Superresolution images ease and improve theimagery analysis wrt� Speckle reduction without spatial resolution loss.� Better border definition.� Volumetric features and textures: forest, trees,...� Small features.

� Drawbacks :�Higher cost: at least 3-4 images are needed to obtain an
acceptable SSI image.�Choice of the dates is very important for a proper interpretation
of the changes.
