the basic data required to support decision making concerning the common subregional issues.
2. Non-core Datasets
additional environmental datasets of potential value, but which may only be relevant to one country,
local region, or a sub-set of projects. Such datasets may evolve into core datasets at a later date
3. Output Datasets
these datasets are derived from the core and non-core datasets and from additional project specific
data through the use of the processing functions (such as GIS) of SEMIS.
4. Auxiliary Datasets
also called "metadata or "codata", this is data that helps to access, use and manage SEMIS. This
includes information on current standards, quality of datasets, data catalogues, available expertise
The core datasets are the principal focus of this paper, and their relationships are presented in detail in the following
Section. Figure 3 indicates the datasets included in each data group.
