Africa Wilson & Henderson-Sellers Secondary Vegetation Classes and Class Reliability, 1985

The Wilson and Henderson-Sellers Secondary Vegetation Classes and Class Reliability data sets are part of the "Wilson Henderson-Sellers land cover and soils for global circulation modeling project " and were developed by the World Data Center-A (WDC-A) for Solid Earth Geophysics, operated by the US National Geophysical Data Center (NGDC). The data sets are part of the World Data Bank II. This data Bank is provided in a Database on diskette called ""The Global Change Data Base"". The Data Bank II is part of larger project called "Global Ecosystems Database Project". This is a cooperative effort between the National Oceanic and Atmospheric Administration (NOAA), NGDC and the US Environmental Protection Agency (EPA). The National Center for Geographic Information and Analyses (NCGIA) in Santa Barbara, California joined the project to assist with training and evaluation. A nominal 10 arc-minute scale was chosen to provide compatibility with other scales and because this corresponds closely with the resolution of global AVHRR coverage. All data are provided in geographic (longitude/latitude) projection. The data sets are accompanied by an ASCII documentation file which contains information necessary for the use of the dataset in GIS or other software.
