8. Data Organization

Data 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 BRSOL11D.taz comprised of 2,075,476 8-bit bytes.

Data Format:
Within the tarred and GNU-zipped file is a compressed file in Arc Info Interchange (.E00) Format - BRSOL11D.E00, which when decompressed will comprise 6,840,095 8-bit bytes, and a copy of the online readme file distributed with this dataset by UNEP/GRID-Sioux Falls (BRSOL11D.HTM).

Any Other Relevant Information about the Study:

According to the readme file attached to these data:
"The information contained in the map is highly generalized. The scale is very small and there is not soil uniformity in large expanses. The map units are predominantly associations of several soil types; of these, only the principal ones are specificied within each map unit. The naming of each map unit is given according to the areal importance of those soil types that are contained in each association. Soil types with little areal importance are not listed.

The composition of the map units is not entirely consistent across the full range of the map, nor is the precision of the map unit boundaries uniform."
