ABSTRACT: Light Detection and Ranging (LiDAR) systems have great potential to facilitate monitoring of infrastructure and vegetation across large areas. In this research, we conducted a pilot study to explore the capabilities of using high resolution LiDAR (>25 pts / m2) to assess utility infrastructure and roadside vegetation in Connecticut. We further explored ways to reduce costs associated with LiDAR acquisitions in order to make recurring data collections more feasible. In the pilot study, a vendor acquired airborne and mobile LiDAR data for a 30 km2 area in Greenwich, CT. The vendor used the data to map poles, lines, and tree crowns from aerial data; mobile data were used to inventory and assess pole attachments as well as measure pole lean and height and assess vegetation near lines. In the pilot study, feature extraction costs were 50% of the acquisition costs; to reduce collection future costs, we are developing in-house computer programs for mapping utility infrastructure and vegetation. We are also exploring opportunities for agencies to partner in LiDAR acquisitions to maximize benefits as well as minimize the cost for any given agency. Future research will explore other technologies (e.g. Geiger LiDAR), that may provide more cost-effective alternatives to conventional LiDAR.
