Study Area – The Brazilian Pantanal Seasonal Inundation in the Brazilian Pantanal


Importance threats
Importance, threats… Seasonal Inundation in the Brazilian Pantanal


Radar backscatter variability
Radar Backscatter Variability Seasonal Inundation in the Brazilian Pantanal


HIERARCHICAL CLASSIFICATION STRATEGY Seasonal Inundation in the Brazilian Pantanal


Level 1
Level 1 Seasonal Inundation in the Brazilian Pantanal

Overall Accuracy ~ 81%

Highest degree of confusion between Savanna class and both Forest, and Grasslands/Agriculture due the high degree of cross-over between classes


Level 2
Level 2 Seasonal Inundation in the Brazilian Pantanal

The first temporal flood distribution data of the entire Pantanal over one hydrological cycle


Current research new and improved
Current research...(new and improved!) Seasonal Inundation in the Brazilian Pantanal

Fine spatial resolution 12.5m L and C-band dual-season for Nhecolândia sub-region;

Additional dates and addition of dual-season 50m for coarse resolution Pantanal flood analysis for 100m


Will be used for: Seasonal Inundation in the Brazilian Pantanal1) ongoing local habitat studies in the region (marsh deer, jaguar)2) Baseline data for monitoring3) Important information to aid in defining conservation areas
