Original land cover information used in this map originates from two sources:
- for Central America: CCAD/WB, 2001. Ecosystems map of Central America, 1:250.000, J.R. Jones, CATIE.
- for South America: Eva, H.D. et al., 2002. A vegetation map of South America. EUR 20159 EN, European Commission, Joint
Research Centre, Luxembourg.
In addition, many national data sources were used to enhance land use information (IBGE census in Brazil, national land
use maps for Colombia and the Central American countries, census data for Honduras, etc.).
Separate ArcInfo grid files are provided for Central and South America. The first at a resolution of 1km, and the latter
only at the resolution used for the modelling exercise (3km).
