North Dakota has seen a lot of industrial growth in the last decade, putting a strain on existing infrastructure. Continental Mapping was contracted to provide aerial lidar derived mapping of a 16.2-mile section of Route 27 in order to improve the existing roadway surface, making it able to withstand a barrage of heavy truck traffic and improve the route’s overall safety.
Transportation consulting services included preliminary design, design, environmental documentation and right of way acquisition. Continental Mapping's role in this project was to provide the geospatial data to support all the transportation engineering services. Continental Mapping decided upon a dual approach of photogrammetric mapping and aerial lidar with a primary focus of supporting structural improvement analysis and the safety enhancements study.
The digital mapping corridor for topographic and planimetric features was centered along the roadway - extending 200’ left and right of the centerline and widening to 500’ at all intersections. Continental Mapping acquired aerial lidar for the project site at a density of no less than 8 points per square meter. New color aerial imagery was flown to support a 1” =50’ scale horizontal accuracy throughout the 16.2-mile corridor.
