Title: Africa Zobler Soils (Texture Classes, Slope, Phases), 1987
Description:
Abstract:
The Zobler soil datasets were developed by the World Data Center-A (WDC-A) for Solid Earth Geophysics, operated by the U.S. National Geophysical Data Center (NGDC). The data set is part of the World Data Bank II and is part of "The Global Change Data Base". The World Data Bank II is part of a larger project called "Global Ecosystems Database Project". The project was a joint effort between the National Oceanic and Atmospheric Administration (NOAA), NGDC and the U.S. 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 dataset is accompanied by an ASCII documentation file which contains information necessary for use of the dataset in a GIS or other software. The texture data is based on the FAO Soil Map of the World, and compiled into digital form by Zobler. Each matrix element represents the near-surface texture (upper 30 cm) of the dominant soil unit in a one-degree square cell of the earth's surface. The data conforms in location, and nominal classification (land, land-ice, water) to Matthew's vegetation data set. References: FAO. FAO-UNESCO Soil Map of the World (1974). Scale 1:5000000.
