ABSTRACT Time‐correlated single‐photon counting (TCSPC) lidar enables high‐resolution 3D imaging at kilometer range. While previous works have covered long range TCSPC 3D imaging from either stationary or airborne platforms, this is, to the best of our knowledge, the first attempt that use a moving ground vehicle. Fusing measurements taken at different

Subterranean Mine Inspection Using the Prometheus Re‐Configurable Drone
ABSTRACT This paper describes the design, development, and real‐world testing of an autonomous drone for subterranean exploration, known as “Prometheus.” Driven by requirements from industry that the drone be able to be deployed through areas of restricted access, Prometheus was designed to be directly deployed through a 150 mm aperture.

Assessing the Physical Habitat Condition of Navigable Canals and Rivers in England
ABSTRACT Monitoring can identify environmental problems and help to set environmental objectives, design management interventions, and assess environmental responses. The need to monitor rivers for such purposes has long been emphasized, but canals have received less attention.

The abundance of herbaceous vegetation in grassy ecosystems—which cover >25% of the world's land surface—is highly variable and impacts key ecological processes including carbon sequestration and support for grazing wildlife and livestock. Here, we present a method for using high‐resolution, UAV‐borne Light Detection and Ranging (LiDAR) to estimate ...

Aerotainment—A New Paradigm for Sustainable Development in Tourism
ABSTRACT Cities have been testbeds for urban sustainability transition initiatives for nearly 20 years. However, most initiatives related to the visitor economy have tended to overlook the fact that tourism is a system with a complex network of stakeholders reaching well beyond the geographical boundaries of a destination.
