A DESIGN OF BRIDGE STRUCTURE HEALTH MONITORING AND MANAGEMENT SYSTEM BASED ON THREE-DIMENSIONAL GIS MODEL

摘要

Geographical Information System (GIS) is a computer system for capturing, storing, managing, and analyzing spatial data. GIS has been applied in many areas to deal with the geographic distribution of spatial features, such as natural resources management, urban planning, calamity monitoring and others. Currently, most of the GIS applications are based on two-dimensional (2D) vectors or images and are weak in handling three-dimensional (3D) spatial information. Although structural health monitoring information for bridges can be partially managed by 2D GIS, it would be much more efficient with a 3D GIS. This paper presents a design of structural health monitoring and management system for bridges based on 3D GIS. A discussion on the implementation of the design and analysis of the technique are also presented.
