The International Cartographic Association (ICA) has proposed a formal model to describe Spatial Data Infrastructure (SDI) using three of the five viewpoints of the RM-ODP (Reference Model for Open Distributed Processing) framework, which was later adapted by other researchers. However, the adapted ICA model has not been validated for corporate-level SDI. The Companhia Energética de Minas Gerai...
the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
Spatiotemporal data is provided and consumed by many different communities, reaching from groups of environmental experts, over decision makers, to the public.

This paper proposes Systems of Systems (SoS) as a conceptual framework to support the creation, evolution and study of Spatial Data Infrastructures (SDIs). After reviewing the relationship between SDIs and generic Information Infrastructures (IIs), a comparison of the latter and SoS is presented. The conclusions of this comparison lead us to propose that IIs can be considered as SoS with severa...
