Abstract:A comprehensive,standardized,and thematically appropriate map of Central American vegetation and landcover types was developed by classifying the remote sensed imagery(AVHRR)1km2 resolution using advanced digital image processing routines and expertise.The map identifies 17 remaining natural vegetation types.The classification accuracy of the map is estimated to exceed 80%.Using a GAP analysis approach,a map of existing and proposed protected areas was overlaid on the vegetation map to analyze the protection status of vegetation types and Ecoregions.
Keywords:landscape level biodiversity  AVHRR  GAP analysis  ecoregions
