Gladstone Visualization

The Gladstone Port Access Road (GPAR) project showcases the utility of 3D visualization for transportation and project planning applications. This visualization was constructed by VizMAP Pty. Ltd. of Mooloolaba, Queensland, Australia to support the local municipal planning authority. This real-time visualization allowed planners and stakeholders to quickly understand the potential impact of the project from any fixed position or along driving paths.

The primary data source for the project was a collection of AutoCAD design files which were handled in different ways, depending upon their content. Surface features were integrated into terrain and maintained the elevation coordinates from the AutoCAD file for accurate placement. Features such as bridges and retaining walls were converted from AutoCAD features to 3D geometry. Some objects such as light poles and traffic signals were imported as models and placed using point references. Linear features for fences and guard rails were used to extrude 3D objects for those features. A color orthophoto was draped across the terrain and used to digitize tree locations and building footprints. These 3D models provided accurate context for the area surrounding the project.

The Gladstone visualization illustrates the high degree integration possible within TerraTools using both GIS and CAD data to support a dense urban area while using geospecific imagery for the backdrop.
