Surveys were conducted in and around NSW Coastal and State Waters, using 1) single-beam echosounder, 2) terrestrial laser scanner and/or 3) pole-mounted Leica positioning unit (beach cross section) for the state’s coastal surveying program. The program is ongoing and provides highly accurate and precise, fine-scale elevation data for NSW nearshore, estuaries and beaches. Single-beam and beach cross-section surveys are most often provided as 5m binned along track transect data whereas laser scanner data are usually better than 5m binned grids for use in GIS applications. Data are often combined and issued as PDF survey maps relative to Local or Australian Height Datum. Generally, survey and data processing details are included as txt format files or more recently (>2011) in a scientific rigour statement. A shape file is also provided showing the geographic coverage of the survey (ESRI shapefile and Google KMZ formats).Maintenance and Update Frequency: asNeededStatement: The dataset is updated with regular frequency to include newly surveyed areas. The database was consolidated in 2011 from surveys conducted by various NSW state agencies since the 1980s when the initial surveys were undertaken. Various vessels (aluminium catamaran and single-hulls, inflatables, jetskis), quad-bikes (side-by-side), survey legs and poles have been employed in the surveys with increasing data acquisition capacity and accuracy achieved with ensuing technological upgrades. Equipment, data acquisition and processing is managed by OEH Hydrographic Surveyor Stephen Holtznagel. Surveys utilise GPS positioning and prior to 2011-12 relied on GPS radio-link setups over State Survey Marks to achioeve RTK (XYZ sub-decimetre accuracy) corrections. Since 2011 RTK corrections are delivered over the mobile phone network through CORSnet.&rft.creator=Office of Environment and Heritage (OEH), New South Wales Government &rft.date=2017&rft.coverage=149,-38 149,-36 150,-36 150,-33 151,-33 151,-32 152,-32 152,-29 153,-29 153,-28 154,-28 154,-32 153,-32 153,-33 152,-33 152,-35 151,-35 151,-37 150,-37 150,-38&rft.coverage=uplimit=2228; downlimit=100&rft.coverage=uplimit=2228; downlimit=100&rft_rights=&rft_rights= http://creativecommons.org/licenses/by/4.0/&rft_rights=https://licensebuttons.net/l/by/4.0/88x31.png&rft_rights=WWW:LINK-1.0-http--related&rft_rights=License Graphic&rft_rights=Creative Commons Attribution 4.0 International License&rft_rights=http://creativecommons.org/international/&rft_rights=WWW:LINK-1.0-http--related&rft_rights=WWW:LINK-1.0-http--related&rft_rights=License Text&rft_rights=The citation in a list of references is: State of New South Wales and Office of Environment and Heritage (OEH) [year-of-data-download], [Title], [data-access-url], accessed [date-of-access].&rft_rights=Creative Commons Attribution 4.0 International License http://creativecommons.org/licenses/by/4.0&rft_subject=oceans&rft_subject=WATER DEPTH&rft_subject=EARTH SCIENCE&rft_subject=OCEANS&rft_subject=BATHYMETRY/SEAFLOOR TOPOGRAPHY&rft_subject=SEAFLOOR TOPOGRAPHY&rft_subject=ACOUSTIC SCATTERING&rft_subject=OCEAN ACOUSTICS&rft_subject=MARINE HABITAT&rft_subject=BIOSPHERE&rft_subject=AQUATIC ECOSYSTEMS&rft_subject=CORAL REEFS&rft_subject=COASTAL PROCESSES&rft_subject=BEACHES&rft_subject=ESTUARIES&rft_subject=COASTAL ELEVATION&rft_subject=TOPOGRAPHY&rft_subject=LAND SURFACE&rft_subject=Global / Oceans | Pacific Ocean&rft_subject=Regional Seas | Tasman Sea&rft_subject=Countries | Australia&rft_subject=States, Territories (Australia) | New South Wales&rft_subject=Field Surveys | Underwater Surveys&rft_subject=Physical Oceanography&rft_subject=research vessel&rft_subject=Sea-floor depth below surface of the water body&rft.type=dataset&rft.language=English Access the data

Brief description

Data products from elevation/bathymetry surveys carried out by the New South Wales Office of Environment and Heritage (OEH). Surveys were conducted in and around NSW Coastal and State Waters, using 1) single-beam echosounder, 2) terrestrial laser scanner and/or 3) pole-mounted Leica positioning unit (beach cross section) for the state’s coastal surveying program. The program is ongoing and provides highly accurate and precise, fine-scale elevation data for NSW nearshore, estuaries and beaches. Single-beam and beach cross-section surveys are most often provided as 5m binned along track transect data whereas laser scanner data are usually better than 5m binned grids for use in GIS applications. Data are often combined and issued as PDF survey maps relative to Local or Australian Height Datum. Generally, survey and data processing details are included as txt format files or more recently (>2011) in a "scientific rigour" statement. A shape file is also provided showing the geographic coverage of the survey (ESRI shapefile and Google KMZ formats).
