Remote Sensing Article 1

Professor David Woo Remote Sensing and Image commentary Dec 1 2010 Mapping irrigated atomic number 18a in Mediterranean basins using let loose approach mawkish satellite priming coat Observation The roll discussed in this article was started callable to the excessive occasion of irrigated pee in the Mediterranean. This excessive use caused loss of the knowledge domains fresh peeing resources by the aquifers in the area creation depleted, agri-chemicals being discharged and saltwater intrusion was accelerated. To make these issues little prevalent, the European Commission started the wet Framework Directive(WFD), who are obligated for the improvement of the water persona and adequate amounts of clean water for all farming puposes. With water being a worthy resource to the Mediterranean and the accompaniment that the residents in the basin areas are low income, the researchers are in search of a low cost answer for the map of irrigated areas using satel lite Earth Observation. The research methodology for this trade union movement included keeping a low cost for selective information analysis. The researchers started with choosing both locations to study, unmatched a test put and one a demonstration site; the Mygdonia basin, which is located in a tectonic depression in northern Greece, and the Strimonas river basin. The Mygdonia basin flows into two lakes; Lake Koronia and Lake Volvi.

The Strimonas basin flows into one chief(prenominal) lake; Lake Kerkini. There were previous satellite images that were captured in 2003 by the ASTER(Advanced Spaceborne t hermal Emission and Reflection Radiometer) s! ensor on board the Terra satellite . These images were then enhanced to better entrance the basin area and also followed the model of keeping the project low cost. towering accuracy guides were another part of the methodology. The researchers findings were a great success. They tack together that that irrigated land can be identified by the result of irrigation , meaning the existence of greenish photosynthesizing vegetation in the dry summer, thus avoiding costly field...If you indispensableness to get a ample essay, order it on our website: OrderCustomPaper.com
