Gathering highly accurate, detailed survey data for improvements to existing roadways can be dangerous and expensive. Traditional surveying does not always provide the detail needed for roadway improvement projects and can be dangerous in areas with heavy traffic. Keeping surveyors safe while obtaining accurate information often requires lane closures which impedes traffic flow and costs the public time and money. Terrestrial laser scanning, also known as high-definition surveying (HDS) is an accurate, safe, and cost-effective alternative.

Using HDS in conjunction with proven workflow and procedures, SmartGeoMetrics™ offers training and support in detailed, cost-effective topographic surveys of highways, tollways, urban arterial roadways, bridges, and elevated structures.

On a typical project, detailed three-dimensional (3D) data is remotely captured with an average of 3-inch spacing or better throughout the entire project. Each data point has a 3D coordinate value relative to the desired coordinate system when supplemented with control monuments tied using traditional surveying methods. This dense “point cloud” data is then referenced and a technician using AutoCAD or Microstation extracts the necessary vector information. The data is also decimated and used to create detailed digital terrain models (DTM) representing a very accurate depiction of the actual roadway. Beyond typical topographic data, information such as the location of pavement failures, cracks, areas of stress and possible ponding, and aerial utilities within and beyond the project limits are easily identified. SmartGeoMetrics also uses this cutting-edge technology to collect very precise deformation measurements for monitoring surface deviations. In the past, it was not economically possible to capture this level of detail, but SmartGeoMetrics has repeatedly proven the benefits of this service to the transportation industry.

When your project demands superior surveying accuracy, SmartGeoMetrics’ terrestrial laser-scanning support services can save time, money, and lives.
