An anonymous reader writes: Maps which are well designed representations of important road data are increasingly being used for displaying facts that lead to better decisions. This is especially true of the way State DOTs are adapting their GIS assets for visualization and decision making. For example GIS data templates can show congested bottlenecks, infrastructure weaknesses (aging or over capacity bridges), artifact displays can show further details that indicate solutions to such problems. Data visualization solutions are the key to using the significant mass of data assets available to State DOTs.
State Departments of Transportation (DOT) are adapting their Geographic Information System (GIS) assets for better visualization and project decision making. They are using GIS data templates to direct their investments by finding congestion, bottlenecks, aging infrastructure, and needed mass transit routes.
With the complexity of modern project planning, State DOTs now demand web based GIS editing software. They have built their own where the vendor options have proved lacking. The breadth of stakeholders and regulators for transportation projects has brought a requirement to annotate data with user friendly cross platform tools. No longer can GIS systems stay in the hands of a small elite group using esoteric interfaces. GIS is now out in the field on mobile platforms. Users demand that their GPS locators be used to find their location on the map so they can annotate in real time on their tablet devices the issues they see in front of them.
DOT Transportation Asset Management (TAM) frameworks have traditionally been database and document based and have required adaptation for visual GIS data. Now live data feeds and reports need to added to the mix. Most TAM programs to date have been developed internally because of a lack of vendor support. This represents a massive duplication of effort between the states and between different agencies within each state. Worse yet this risks confusion in the data models for interstate or even intrastate projects. Despite these challenges agencies are pressing ahead with advanced 3D visualizations, asset display layers, statistical and comparative modules. Software is being adapted from all sources just to keep up with their pressing needs.
