IEA Training Manual - Module 4

3. Information systems

You have seen that data, indicators and indices form an interlinked information system. While these elements are all related, developing them involves specific tasks. This section will provide an overview of some of the key conceptual issues and methods in developing data for use in indicators and indices.

The section reviews the types of data, including quantitative and qualitative data, and also looks at the specific issues related to spatial and non-spatial data. The section also considers what is involved in monitoring, construction and use of databases to store and analyze data. One of the prominent examples reviewed at the end of the section is the GEO Data Portal, a global database maintained by UNEP that is used in the production of global and sub-global GEO assessments.
