Wetland mapping and monitoring with RADARSAT

摘要

Wetlands are important components of ecosystems because of their in the maintenance of environmental quality and bio-diversity.Increasingly,wetlands have been under stress due to drainae activities and subsequent habitat fragmentation.Their improtance to a healthy environment and hte growing public awareness of their plight has generated the need for effective management approaches to wetland conservation,including the use of remote sensing data.this paper reviews the role of RADARSAT in mapping and monitoring wetlands,with examples of reserch results and studies from North and South America used to support the discussion.
