Africa Soil Classification by ZoblerEntry ID: NBId0025_101
Abstract: New-ID: NBI25
Africa ZOBLER Soil Type, Soil Texture, Surface Slope Classes
The IMG files are in IDRISI format The Zobler soil type, soil
texture and surface slope dataset was developed by the World Data
... Center-A (WDC-A) for Solid Earth Geophysics, operated by the U.S.
National Geophysical Data Center (NGDC). The dataset is part of the
World Data Bank II provided on a diskette called The Global Change
Data Base. The Data Bank II is part of a larger project called Global
Ecosystems Database Project. This is a cooperation 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
The dataset is accompanied by an ASCII documentation file which contains
information necessary for use of the dataset in a GIS or other software.
