Experts' and Novices' Use of Gesture in Explaining Geologic Maps

People gesture during spatial tasks (Alibali et al., 2001; Kita & Özyürek, 2003; Morsella & Krauss, 2004), and how they gesture reveals information about ongoing cognitive processes (Alibali & Kita, 2008; Church & Goldin-Meadow, 1986; Schwartz & Black, 1996). One task that requires many spatial processes is reading geologic maps. Geologic maps give information about the spatial relationships of...

A Framework and Methods for Characterizing Uncertainty in Geologic Maps

Geologic maps are products of complex analyses and interpretations, and as such, contain a certain amount of uncertainty. Unfortunately, it is difficult to estimate the uncertainty within a geologic map. Much of this difficulty is due to the lack of a clear framework for describing the sources of uncertainty within the map and poor awareness, within the mapping community, of methods capable of ...

A System for Semantic Integration of Geologic Maps via Ontologies∗

This paper describes a prototype system for registering geologic data sets through ontologies to assist in integrating and querying heterogeneous geologic data sets. The system consists of three components: an ontology repository, the data set registration, and ontology-aware applications. User-defined ontologies in OWL are saved and used by the system. Each data set must be registered before i...
