National Center for Geographic Information and Analysis

In 1998, the National Center for Geographic Information and Analysis (NCGIA) organized a multi-pronged research project entitled "Uncertainty in Geospatial Information Representation, Analysis, and Decision Support". The goal of the research was to improve the mechanisms by which users of the defense geospatial information infrastructure are made aware of the presence of uncertainty in data, and its implications for decision-making. Six areas were addressed in a coordinated approach- elements of uncertainty, measures, models, portrayal, propagation, and higher dimensions. The research was conducted by five teams, with frequent opportunity for cross-fertilization between them. 

This document provides the research goals, primary investigators (PIs), researchers and overviews of the investigated topics of the project. A bibliography of relevant literature is also included.
