Tropical Forest Area Measurement from Global Land-Cover Classifications: Inverse Calibration Models Based on Spatial Textures

Retrieving area estimates from broad scale land-cover maps is unaccurate dude to the spatial aggregation. In a previous study, we tested a method to calibrate area estimates of tropical forest cover by inverting a model of the influence of the spatial fragmentation on the spatial aggregation bias. In this study, improvements of this previous model are sought by better accounting for the spatial variability using texture measures and by integrating spatial information in the mixed pixel estimator. The integration of spatial information into a correction model to retrieve fine resolution proportiones from coarse resolution data improves the reliability of the estimates by up to 35%.
