In many domains, users are confronted with large volumes of information from a variety of sources. In addition to understanding the content of the information, they need to understand and reason about potential qualifiers of the information. These qualifiers, or meta-information, include characteristics such as the uncertainty associated with the data, the age of the data, and the source of the data. There is a long history of research in scientific visualization and geospatial information systems which has considered visual techniques for representing complex information, in both spatial and non-spatial frames of reference. Our own research has considered how visual techniques such as pixilation, transparency, saturation, and texture can be used to represent a variety of meta-information categories. This talk will survey results from a number of empirical studies which have examined how people interpret meta-information visualization regarding geospatial regions and objects, how different visualizations impact decision-making and task performance, and how these measure are affected by type of meta-information, task demands, and visual context.
