GIS - ITS Backbone
The development of a digital terrain database, using the innovative airborne LIDAR mapping
technology and color aerial georeferenced photo, is an important component of the GIS
supporting the ITS project for Oxford. It is a cost-effective, efficient method for creating highresolution
digital terrain models and contours. The resulting GIS precision database forms the
rural ITS backbone. The GIS will have separate layers for terrain data, photos, and transportation
networks. All important inventory and condition data attributes, layers of road network and
signals, and eventually real-time traffic surveillance data will be incorporated in this
comprehensive and accurate GIS. The GIS will be designed to accommodate differing
infrastructure components and will be integrated with user-friendly asset management software,
as shown in Figure 7.
