Abstract:This report introduces the design and implementation of a Web-based bridge information visual analytics system. This
project integrates Internet, multiple databases, remote sensing, and other visualization technologies. The result
combines a GIS database with other visualization system called Bridge Web-based, GIS Integration (Bridge-WGI),
developed for evaluating and maintaining the national bridge information system (NBIS). Web-GIS based application
incorporates national bridge inventory (NBI) data, remote sensing data generated by LiDAR scans, small format aerial
photography (SFAP), and decision-making support modules, into a general framework with a user-friendly interface
and easy Internet accessibility.
The guiding objective of this analytical tool is to enhance the capability of the National Bridge Inspection System
(NBIS) through:
1) providing a better interpretation of bridge condition information;
2) providing a decision support module for bridge maintenance;
3) providing data entry and visualization functionalities for various information (text, image, and documents); and
4) providing a report generating tool for easier to interpret bridge information.
Bridge-WGI captures all the conventional functionalities of a Web 2.0 application. With Bridge-WGI, there is a
capability for Bridge Management Systems (BMS) to migrate into an open architecture, secured access, and robust
interactivity. Benefitting from Internet interactivity, Bridge-WGI is another step toward “anytime anywhere” global
connectivity objectives. Interactive visualization provide various data interpretations including general bridge
information, visual analytics, bridge condition distribution mapping, statistical graphs, conditional bridge search, pre-caution alarm, and maintenance decision support. A bridge data tablet application helps bridge inspectors input bridge
data easily via the Internet.
