    • 2019 NOAA Bathymetric Lidar with Waveform Metrics: Saipan, CNMI

    Metadata Updated: October 18, 2024

    This data package contains bathymetric light detection and ranging (lidar) Chiroptera-4X .LAS 1.4 files with waveform metrics (as extra bytes) for 0 to 50 meter depths around the island of Saipan, Commonwealth of the Northern Mariana Islands (CNMI). Bathymetric lidar waveforms depict the amount of laser light returned from the seafloor recorded during each laser pulse. Typically, only the leading edge of the seafloor return is used to calculate bottom depth. However, the shape of the seafloor return also contains novel information about the physical structure and biological cover on the seafloor (Collin et al. 2011, Wilson et al. 2019). To extract this information, the National Oceanic and Atmospheric Administration (NOAA) National Centers for Coastal Ocean Science (NCCOS) partnered with Oregon State University (OSU), NOAA Office for Coastal Management (OCM), Woolpert and Hexagon Leica to develop software to export, process, normalize and rasterize 16 LWFM describing the shape of the seafloor return (Jung et al. In Review; Collin et al. 2011; Parrish et al. 2014; Kashani et al. 2015; Kogut et al. 2022). The resulting LWFM rasters were used to predict the distribution of key coral reef taxa and habitats west of Saipan (Costa et al. 2024). This effort marks one of the few studies that have used LWFM to predict tropical coral reef habitats to date. These processing workflows and associated software will also make LWFM creation easier and more routine for future Chiroptera-4X lidar collections by NOAA and its partners. This project was funded by NOAA's Coral Reef Conservation Program (CRCP), and leverages significant investments made by NOAA NCCOS, NOAA National Geodetic Survey, NOAA Office for Coastal Management, and the U.S. Geological Survey in the region.

    Lineage This data was collected by Woolpert, Inc. for the USGS and NOAA Office for Coastal Management (OCM). The LiDAR data was collected for Saipan from 11 Jul to 21 Aug 2019. The bathymetry was georeferenced horizontally to the North American Datum 1983 (NAD83), Universal Transverse Mercator, Zone 55 North (UTM 55N, meters) and vertically to the Northern Marianas Vertical Datum of 2003 (NMVD03, meters) coordinate systems. All lidar data for this project were collected to meet National Geospatial Program Lidar Base Specification Version 1.3 QL1 standard, while simultaneously acquiring bathymetric lidar data at National Coastal Mapping Strategy 1.0 QL2b standard. The Root Mean Square Delta z (RMSDz) was 0.033 for Saipan when comparing adjacent flight lines. For more information, please see NOAA and USGS 2019. Waveform metrics were added by Woolpert, Inc., Oregon State University and NOAA National Centers for Coastal Ocean Science (NCCOS). Data were reduced to geographic coordinates on the ellipsoid for ingest in the Digital Coast by NOAA OCM.
