- W3000578380 abstract "The snow cover plays an important role in the hydrological cycle of Quebec (Eastern Canada). Consequently,evaluating its spatial extent interests the authorities responsible for the management of water resources, especiallyhydropower companies. The main objective of this study is the development of a snow-cover mapping strategyusing remote sensing data and ensemble based systems techniques. Planned to be tested in a near real-time operationalmode, this snow-cover mapping strategy has the advantage to provide the probability of a pixel to besnow covered and its uncertainty. Ensemble systems are made of two key components. First, a method is neededto build an ensemble of classifiers that is diverse as much as possible. Second, an approach is required to combinethe outputs of individual classifiers that make up the ensemble in such a way that correct decisions are ampli-fied, and incorrect ones are cancelled out. In this study, we demonstrate the potential of ensemble systems tosnow-cover mapping using remote sensing data. The chosen classifier is a sequential thresholds algorithm usingNOAA-AVHRR data adapted to conditions over Eastern Canada. Its special feature is the use of a combinationof six sequential thresholds varying according to the day in the winter season. Two versions of the snow-covermapping algorithm have been developed: one is specific for autumn (from October 1st to December 31st) and theother for spring (from March 16th to May 31st). In order to build the ensemble based system, different versionsof the algorithm are created by varying randomly its parameters. One hundred of the versions are included in theensemble. The probability of a pixel to be snow, no-snow or cloud covered corresponds to the amount of votesthe pixel has been classified as such by all classifiers. The overall performance of ensemble based mapping iscompared to the overall performance of the chosen classifier, and also with ground observations at meteorologicalstations." @default.
