NSW Marine LiDAR Topo-Bathy 2011 Geotif

Remotely sensed topographic (elevation) and bathymetric (depth) information were acquired targeted sections of the NSW coast (Tweed Heads, Byron Bay, Port Stephens, Central Coast) using Airborne LiDAR Bathymetry (ALB - a combination of Light Detection And Ranging (LiDAR) and Laser Airborne Depth Sounding (LADS) sensors) during June - July 2011. This resource is a shapefile that defines the combined extent (428 km2) for the four surveyed areas. Data were acquired by Fugro Pty Ltd on behalf of NSW Office of Environment and Heritage (now NSW Department of Planning and Environment) using a Riegl VQ-820-G ALB (LiDAR) and Fugro LADS High-Definition sensors aboard sub-contracted Corporate Air Cessna C441 (VH-VEH). Funding was provided through NSW Office of Environment and Heritage with an objective to acquire high quality, high resolution baseline data to support coastal erosion studies The survey requirement was to provide data at a minimum of 5 x 5 m laser spot spacings from the mean high-water mark to a minimum of 200m inland, and from the shore, seaward (LADS - bathymetry) to the point of laser extinction (~30m water depth depending on in-water conditions). Positioning data were collected on the ellipsoid ITRF 2014 GRS80 in UTM Z56 and post-processed using local base stations (CORSnet NSW) to provide a Post Processed Kinematic GNSS solution for final aircraft trajectory before being applied to all data. Data types available are as GeoTiff (L3) transformed to GDA94 Z56. Other data types may be available as ESRI topo-bathy rasters and contours, tab delimited ascii XYZ, relative reflectance data (terrestrial, marine) and Quality Control (QC) documentation (contained within survey report) via the NSW DCCEEW Information Asset Register (IAR) (metadata, coverage shape), SEED (https://seed.nsw.gov.au or upon request. The data are intended to inform coastal and marine management and are ‘not for navigation’.
