Historically, Synthetic Aperture Radar (SAR) data was made available later than optical data for the purpose of land cover classification (Landsat Legacy Project Website, http://library01.gsfc.nasa.gov/landsat/; NASA Jet Propulsion Laboratory: Missions, http://jpl.nasa.gov/missions/missiondetails.cfm?mission=Seasat); in more recent times, the milestone of spaceborne meter resolution was reached by multispectral optical data first (Ikonos; GEOEye Imagery Sources, http://www.geoeye.com/CorpSite/products/imagery-sources/Default.aspx#ikonos), followed a few years later by radar data (COSMO/SkyMed [Caltagirone et al. 2001] and TerraSAR-X [Werninghaus et al. 2004]). As a consequence, more experience has been accumulated on the extraction of cartographic features from optical rather than SAR data, although in some cases radar data is highly recommendable because of frequent cloud cover (Attema et al. 1998) or because the information of interest is better visible at the microwave frequencies rather than at the optical ones (Kurosu et al. 1995).

Abstract
Historically, Synthetic Aperture Radar (SAR) data was made available later than optical data for the purpose of land cover classification (Landsat Legacy Project Website, http://library01.gsfc.nasa.gov/landsat/; NASA Jet Propulsion Laboratory: Missions, http://jpl.nasa.gov/missions/missiondetails.cfm?mission=Seasat); in more recent times, the milestone of spaceborne meter resolution was reached by multispectral optical data first (Ikonos; GEOEye Imagery Sources, http://www.geoeye.com/CorpSite/products/imagery-sources/Default.aspx#ikonos), followed a few years later by radar data (COSMO/SkyMed [Caltagirone et al. 2001] and TerraSAR-X [Werninghaus et al. 2004]). As a consequence, more experience has been accumulated on the extraction of cartographic features from optical rather than SAR data, although in some cases radar data is highly recommendable because of frequent cloud cover (Attema et al. 1998) or because the information of interest is better visible at the microwave frequencies rather than at the optical ones (Kurosu et al. 1995).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
