• UAS for shallow bathymetric mapping (Slocum et al., 2019; Lambert and Parrish, 2023)
• simUAS: computer graphics rendering workflow for generating scenes of simulated UAS imagery for analyzing structure from motion (SfM) outputs (Slocum and Parrish, 2017)
• Investigation of computationally-simple, shape-based lidar waveform features (e.g., statistical moments, numerical integrals, and slopes) for enhanced analysis of spatially-varying elevation uncertainty and coastal mapping
• Use of topographic-bathymetric (“topo-bathy”) lidar for mapping benthic habitats, including coral reef and seagrass habitats (Wilson et al., 2019)
• UAS and lidar for traffic network monitoring
• Use of UAS for bridge inspections (collaborative research with Dr. Dan Gillins)
