Caribbean Land Cover Analyses

Data Products

Forest formation and land cover map series for the Caribbean islands were developed from Landsat Enhanced Thematic Mapper Plus (ETM+) and SPOT imagery as part of a multi-organizational project. We used decision tree classification methods to classify the Landsat imagery for Puerto Rico (including Vieques and Culebra islands) (Kennaway, submitted), St. Kitts and Nevis, St. Lucia, St. Vincent and the Grenadines, and Grenada. SPOT imagery was included for the analysis of Dominica. The woody vegetation classification scheme relates closely to that described in "A guide to Caribbean vegetation types: classification systems and descriptions" by Areces-Malea (1999). This scheme classifies Caribbean vegetation according to standards of the U.S. Federal Geographic Data Committee, with modifications similar to those in "Mapping forest types and land cover of Puerto Rico, a component of the Caribbean biodiversity hotspot" by Helmer (2002). For each mapping area, the decision trees were used to classify a stack of raster layers that included the Landsat image bands and various ancillary raster data layers. Both the forest formation and land cover datasets and ancillary data are listed below for download. These dataset are available in varying data types, please refer to the associated metadata for details.
