| Tiivistelmä: | In this article, it evaluates the accuracy of four global and regional forest cover assessments (MODIS, IGBP, GLC2000, PROARCA) as tools for baseline estimation. They conduct this research at the national scale for Costa Rica and for two tropical dry forest study sites in Costa Rica (Santa Rosa) and Mexico (Chamela-Cuixmala). It is found that: 1) at the national level, the total forest cover accuracy of the four land cover maps was inflated due to an overestimation of forest in areas with an evergreen canopy. 2) the four maps greatly underestimated the extent of the deciduous forest (dry forest), an ecosystem that faces high deforestation pressure and poses complications to the mapping of its extent from remotely sensed data. 3) for the tropical dry forest sites, all maps have low forest cover accuracies (mean for Santa Rosa: 27%; mean for Chamela-Cuixmala: 56%). 4) this has implications for policy implementation. |
