DESCRIPTION:Dr. Ismael Colomina\, Director\, Institute of Geomatics and He
 ad of Integrated Geodesy and Navigation Unit\, Castelldefels\, Spain\n\nIn
  recent times\, unmanned aerial systems (UAS) have been identified as a va
 luable technology for close-range Earth observation. Although the UAS conc
 ept covers a wide range of systems -from few tens of grams to more than th
 ousand kilograms\, from low altitude to stratospheric aircraft\, from scie
 ntific to military-\, small UAS are dominating the scene in geomatics appl
 ications and\, today\, one can say that UAS is the enabling technology for
  aerial close-range photogrammetry and remote sensing.\n\nIt seems concept
 ually clear and everyday practice confirms that "aerial close-range photog
 rammetry and remote sensing" for small areas from unmanned platforms has a
 dvantages like affordability\, flexibility and transportability with respe
 ct to existing technologies. As a result\, UAS-based data acquisition and 
 processing\, has established itself as the fourth mapping paradigm followi
 ng the aerial\, space and terrestrial mobile ones. Moreover\, from the out
 set\, it has been applied to topographic\, agricultural and environmental 
 mapping. And\, since fabricating and buying UAS is far less expensive than
  fabricating and buying planes\, a new sector of small and medium entrerpr
 ises (SME) has emerged. These SME companies offer from UAS components\, to
  UAS full fledged systems\, to services and to small sensors. For the same
  reason\, research on UAS applications is flourishing at universities.\n\n
 As promising as they might be\, UAS technology and procedures are young an
 d\, as elsewhere\, there are problems and challenges. Navigation and imagi
 ng sensors shall be small and lightweight\, missions shall last enough\, u
 nmanned aircraft shall stand the sometimes extreme environment conditions 
 like wind\, rain and temperature. And they have to avoid crashes to other 
 aircraft and to other natural and artificial objects. Moreover\, recent ex
 perience has shown that data acquired in UAS missions cannot just be proce
 ssed with the existing software for manned aerial systems.\n\nIn the prese
 ntation a short review of UAS remote sensing will be provided\, the actual
  possibilities and limitations will be highlited and the challenges ahead 
 to make the technolgy mature for applications identified.
