Synergistic Use of Multimodal Data for Vegetation Status Monitoring
MetadataShow full item record
Vegetation is important because it provides the foundation of all terrestrial ecosystems. Indicators on vegetation can help track changes in the health and integrity of ecosystems. Also, indicators on vegetation responses to stresses like pollution and land uses can provide early warning of changes in ecosystems that are harder to measure. Various vegetation indicators give information on condition, changes and trends in vegetation. In the same time vegetation is a key issue in constructing Environmental Indicators that reflect the state of the environment. In this context, there is an ongoing need to develop inexpensive, sophisticated tools for the vegetation monitoring. This study proposes a remote sensing based methodology to monitor the vegetation of the island of the Zakynthos island in western Greece. Spatiotemopral changes of the Fraction of Absorbed Photosynthetically Active Radiation (fAPAR) variable are identified. and used to support two of the European Environment Agency’s (EEA) Indicators i.e. Forest fires (EEA CLIM 035) and Land Take (EEA CSI 014) Indicators .
