HIERARCHICAL CLASSIFICATION STRATEGY


Level 1

Level 1

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

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


Current research new and improved

Current research...(new and improved!)

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


Study area the brazilian pantanal

Will be used for:1) ongoing local habitat studies in the region (marsh deer, jaguar)2) Baseline data for monitoring3) Important information to aid in defining conservation areas
