Abstract: Geospatial technologies such as photogrammetry and global navigation satellite systems (GNSS) have been an integral part of highway mapping for decades. However, geospatial technologies continue to evolve, and new technologies are becoming more accessible for a wide range of highway construction applications. Tools such as unmanned aircraft systems (UAS), lidar, aerial imagery, GNSS, automated machine guidance, and their derivative products offer many benefits to the highway construction industry. These benefits include improved efficiencies and streamlined processes, as well as more accurate and reliable data. The key to using these technologies successfully to optimize benefits is to correctly select the appropriate tool for the application and understand limitations. In many cases, data from each of these technologies will be integrated for a project to develop the necessary survey products. This research investigates effective uses of geospatial technology for a wide variety of highway construction and maintenance applications; identifies a number of tools and their related accuracies; offers recommendations for tool selection, workflows, and strategies for conducting benefit-cost analysis (BCA); and analyzes future directions of these technologies in highway project and service delivery applications. The research explores several case studies using these technologies to document their benefits and limitations. In particular, the research determines the return on investment (ROI) associated with using these technologies in several of those case studies.\n
