Building West Virginia DOT s Geospatial Capabilities: GIS Web Portal And Straight-line Diagram Application Current Status, Upcoming Enhancements, and Integration Marshall Burgess, WVDOT Don Kiel, GeoDecisions
Project Need and Benefits What is the Web portal/sld designed to do? Promote access information from a single place Promotes architecture for central database environment, including RIL (new version is well along on SQL Server 6 months off) Integrate with project tracking system Who are users? Administration/decision-makers Districts Engineers Political STIP new Director and combined division that includes statistics, mapping, GIS, and HPMS What are some of the expected benefits? Improved data integrity and consistency Catalyst for finding data problems
What Are Straight Line Diagrams? Used in paper form for years at most state DOT s Effective, simple way to view business data for a portion of roadway Combines straight-line view of road and associated business data GeoDecisions
Sample Hardcopy SLD Project Information Traffic Data Accidents Surface Type & Depths Widths Curves Grades Route Detail Structures Intersecting Roads Railroad Crossings HPMS Sections Traffic Counter Locations
Automating SLDs- Advantages Streamlines maintenance and updating Allows easier sharing of information Can take advantage of leading edge technologies such as geographic information systems Can be enabled for easy viewing and use via the Web Expandable, customizable for individual business needs Can be integral part of a Web portal environment
Why is the SLD Approach Different from Pure GIS? Different way to view and manipulate data Incorporates GIS, but also utilizes other tools Highly integratable into enterprise, Webbased portals, solutions, etc. Advantages over GIS in comparing multiple business data sources
Parts of the SLD Display Tools Stick Diagram Mile Readout Slider Bar Scale Change Data Display
West Virginia SLD-Web Portal Concurrent with building and refining LRS framework Will be incrementally enhanced as business processes become more sophisticated Combined with a GIS Web Framework deliverable as first integrated application Designed to be integrated with videologs, project management system, other applications

Print to PDF, Export Data to Excel
Phase 3 Enhancements and Videologs Integration Begins early 2010 Integrate with videologs viewer Additional enhancements: Continued improvements to map symbology Changes/improvements to imagery/caching environment Support multiple SLD route displays Add ability for network walking Additional data layers for SLD
GeoDecisions DOT SLD Projects Application design, code components have been able to be shared and reused among states VT NH ME PA WV VA
Examples from Other States GeoDecisions
Impacts of WVDOT Project So Far Upgrading database and LRS at same time as conducting project difficult, but has helped more effectively identify and fix problems and incomplete data Planning for and implementation of new datasets (i.e., new videologs) has been promoted and coordinated Ideas for new layers, uses have been readily apparent
