| Abstract | This paper shows that the m-chi decomposition, the Shannon-Entropy model and the Wishart-Chernoff distance can be used to map and monitor wetlands. Areas which changed from flooded vegetation to
non-flooded vegetation were accurately mapped using the m-chi decomposition, and areas that changed from saturated soil to unsaturated soil were visible with the Shannon-Entropy model. In addition,
the Wishart-Chernoff distance was able to map
wetland areas which had changed to a different land cover type over time. |
| Summary | (Plain Language Summary, not published)
Wetlands are one of Canada's most important resources. They provide food and shelter for a variety of wildlife, help offset hydrological events like
floods and act as a filter for sediments and toxins. Flooded vegetation and soil moisture are two important components of a wetland. This study reports on the potential of a new and innovative mode which will be available on Canada's future RADARSAT
Constellation Mission - specifically, compact polarimetry (CP) - to map and monitor flooded vegetation and soil moisture changes within wetlands. Three different models were applied to simulated CP data over a test site. The first was able to
accurately map changes from flooded vegetation to non-flooded vegetation, the second was able to map wetland boundaries (saturated soil), while the third model proved promising as an initial identification of areas of high change within wetlands. A
synergistic approach using all three models has utility for the mapping and monitoring of wetlands. |
