17 Metrics for engineering, planning, restoration, and resilience Geomorphic: elevation/depth, slope, dune characteristics, beach width, substrate size, volume/elevation change, distance to shoreline or dune peak, foredune continuity, channel shape/gradient and other structural characteristics Environmental: terrestrial and aquatic habitat/vegetation type (e.g., SAV, wetlands), TES, invasives, cover density/diversity, fragmentation/connectivity, substrate type, impervious surface, height of vegetation above ground Water: stream length, watershed size, salinity, turbidity, chlorophyll, toxicity exposure Bay Used in: Mapping sea turtle nesting habitat suitability Landscape evolution models Mapping susceptibility to breaching events Identifying opportunities for RSM Coastal infrastructure assessment Beach project monitoring Ecosystem goods and services valuation Quantifying coastal resilience TES conservation webtool Dune Vegetation Dune Elevation Artificial Lighting Beach Width Ocean MHW Nearshore Bar Joint Airborne Lidar Bathymetry Technical Center of Expertise

24 JALBTCX 2017 Challenges Automated data processing Point cloud editing ~ ½ of total time and ¼ cost. Problem areas are low signal to noise (extinction, turbid water) and along the shoreline. Data management Data volumes, backups, archiving, and associated processing unmanageable TB per 4 hour flight Data delivery Future LAS format needs capability to store point-bypoint datum shifts Implement LAS 1.4 Non-proprietary compression algorithms Move to image services Tracking usage of data and outcomes

25 JALBTCX 2017 Opportunities Need a permanent calibration range for continued sensor development and evaluation, or a rapid response capability for calibrations of opportunity including accurate depth, water surface, water column, and seafloor properties. How can we utilize structure-from-motion to augment manned data collections? Identifying requirements for next generation systems open source cloud to real time processing, UAS/OPA capable, better performance in turbid and nearshore environments, etc.
