Evaluating MERIS-Based Aquatic Vegetation Mapping in Lake Victoria
Delineation of aquatic plants and estimation of its surface extent are crucial to the efficient control of its proliferation, and this information can be derived accurately with fine resolution remote sensing products. However, small swath and low observation frequency associated with them may be prohibitive for application to large water bodies with rapid proliferation and dynamic floating aqu...
متن کاملPerformance of Meris Products in Lake Victoria
The newly finished ESA project MERIS Lakes included activity in Lake Victoria to show the potensial for monitoring this eutrophic African Lake. In this study an evaluation of how different processors perform in Lake Victoria. Lack of proper validation data makes it only possible to have a preliminary assessment of the performance of the product algal_2, suspended material and the signal depth, ...
متن کاملUsing Meris for Mountain Vegetation Mapping and Monitoring in Sweden
The objective of this study is to apply ENVISAT MERIS data in mapping mountain vegetation in Sweden. The Swedish mountain vegetation is characterized by mosaics of different land cover types; a single MERIS pixel (300 meter IFOV) can consist of several of these different land cover types. “Hard” classifications which produce a single thematic class per pixel often give a low accuracy. While man...
متن کاملAquatic and shoreline vegetation of Lake Nubia, Sudan
The paper reports on the flora along the banks of Lake Nubia and the long-term changes that have taken place since the formation of the Aswan High Dam (AHD) Lake about 40 years ago. Both aquatic and shoreline vegetation were studied in 15 transects located across the lake, from Debeira (337.5 km south of the Aswan High Dam), to the Dal Cataract (500 km south of AHD). Water temperature, pH, diss...
متن کاملMeris Global Vegetation Index: Evaluation and Performance
This paper overviews the evaluation and the performance of the Medium Resolution Imaging Spectrometer (MERIS) Global Vegetation Index (MGVI) algorithm which is implemented in the MERIS ground segment as the main land surface product, also called the Top Of Atmosphere Vegetation Index (TOAVI). MGVI values represent the Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) which act as...
