VV or HH for urban areas?

Hi all,

Is VV or HH polarization preferable for mapping urban areas, specifically buildings? DualPol is not an option unfortunately.

Stefan Auer published a paper which finds that buildings are more pronounced in HH because of higher intesnsities in various cases: “Buildings in High Resolution SAR Images - Identification based on citygml data”

But it is surely also a matter of incidence angle, direction of buildings towards the sensor and spatial resolution.


Nice - reference - thanks!
