Context and objectives
The aim of the proposed research is to assess the Proba-V data for burned area mapping and post-fire monitoring in Mediterranean ecosystems. The specific objectives of the research are:
- to investigate the potential of multi-temporal Proba-V data for mapping burned areas and monitoring post-fire vegetation recovery in the Peloponnese, Greece,
- to define advantages and disadvantages of Proba-V when compared to SPOT-VGT data in the mapping of burned areas as well as in the monitoring of post-fire vegetation recovery,
- to compare, combine and evaluate different methods for mapping burned areas and monitoring post-fire vegetation recovery by using Proba-V data, and
- to assess the accuracy of the burned area and vegetation recovery maps.
Expected scientific results
The use of SPOT-VEGETATION data have proven to be extremely useful for burned area mapping and monitoring of vegetation recovery in the fire-affected areas. Coarse resolution data such as SPOT VEGETATION are characterized by their frequent revisit capability and their capacity to create long time series of data; these are important factors for mapping inter-annual changes on vegetation phenology and detecting fire outbreaks immediately after a fire event, at regional and national scale (Donoghue 2002; Xiao et al., 2002).Given that the new Proba-V mission will provide data of similar characteristics as with SPOT-VGT but with an improved spatial resolution, it is naturally anticipated that the new Proba-V data will contribute to more accurate measurements related to the impact of fires in the natural environment. In particular, it is expected that the results of this proposed research will show the high capability of the new Proba-V data for burned area mapping and monitoring of vegetation re-growth in fire-affected areas. Moreover, the combination of the new data with advanced methodological approaches is expected to further enhance the potential of Proba-V imagery in producing accurate burned area estimations.
