8. Data OrganizationData Granularity:
A general description of data granularity as it applies to the
IMS appears in the EOSDIS Glossary. This dataset consists of a
single tarred and GNU-zipped of the filename BRVEG11D.taz comprised
of 1,737,525 8-bit bytes.
Data Format:
Within the tarred and GNU-zipped file is a compressed file in
Arc Info Interchange (.E00) Format - BRVEG11D.E00, which when decompressed
will comprise 5,778,838 8-bit bytes, and a copy of the online readme
file distributed with this dataset by UNEP/GRID-Sioux Falls (BRVEG11D.HTM).
