Knowledge-Based Visualization of Multidisciplinary Databases for IDC Interactive Analysis: Region Specific and Global
Abstract
A prototype Geographical Information System (GIS) with global coverage was developed at Cornell University in order to assist the Prototype International Data Center (PIDC) in merging the results of the four monitoring technologies (seismic, hydroacoustic, infrasound, and radionuclide) and to assist in ongoing calibration and location studies during the implementation of the Comprehensive Test Ban Treaty (CTBT). This system is intended to expand the PIDC's capabilities to include the use of non-seismic databases in an interactive way to serve the objectives of the CTBT verification readiness efforts. The GIS provides a rapid analysis tool to assist in discrimination of nuclear from non-nuclear events by placing suspect events in spatially registered displays of diversified, digital databases. These databases include topography, bathymetry, geology, tectonic zones, faults, seismicity, focal mechanisms, velocity and attenuation models, crustal thickness models, depth to metamorphic basement models, cultural landmarks, and Landsat imagery. The system permits rapid access to all data and - graphical fusion of these data with the PIDC results using a simple menu-driven analysis tool and the data are also used for research directed at regional calibration of seismic events. The data may be viewed both internally and over the World Wide Web using commercially available, free GIS software (e.g., ArcExplorer).
