GEOTECHNICAL DATA MANAGEMENT AT THE VIRGINIA DEPARTMENT OF TRANSPORTATION

摘要

This report describes the development and implementation of the geotechnical data managementsystem at the Virginia Department of Transportation (VDOT). The purpose of this project wasto develop a practical, comprehensive, enterprise-wide system for entry, storage, and retrieval ofsubsurface data. The resulting product satisfies the work flow requirements of VDOT andstreamlines the delivery of geotechnical information.Main components consist of gINT software for geotechnical data processing and theESRI Arc Internet Map Server (ArcIMS) for distributed GIS data delivery via a web browser.These programs are currently widely adopted by the geotechnical and GIS user community.Custom command scripts and configuration files were developed in the form of an extensibleapplet framework called GDBMS (Geotechnical Database Management System) to manage andprocess geotechnical data. The project was built on the extensive interaction among VDOTgeologists, engineers, and information technology personnel. Their expertise was harnessed tocreate a system that is user-friendly, rugged, relatively easy to maintain, and capable ofdelivering the required data in a consistent format across operating divisions. GDBMS isflexible enough to be employed by both VDOT designers and VDOT consultants (free access isprovided to these groups). Its greatest advantage is that it greatly improves the efficiency ofgeotechnical data management and delivery on large transportation projects. A free customizedset of support files can be downloaded from the website of VDOT's Materials Division.
