Interactive Analysis of Spatial Subsurface Data Using GIS-Based Tool

Much of the spatial information that is an inherent part of geotechnical and geoenvironmental investigation programs has been underutilized due to the unavailability of analysis tools designed to take advantage of the spatial attributes of the information. This paper describes a system developed to provide a quantitative estimate of the adequacy of coordinate-based information used to make particular decisions, with particular emphasis on geotechnical and geoenvironmental site investigation information. The system was developed using a geographic information system (GIS) as a platform that was integrated with an existing commercial geostatistical software package to allow for more comprehensive analysis and optimization capabilities.
