XYZ Bathymetry Grid North Perth SurveyNote: This metadata describes the dataset in accordance with the ANZLIC (Australia New Zealand Land Information Council) Core Metadata Guidelines Version 2. Dataset citationANZLIC unique identifier: ANZCW0703015695 Title: XYZ Bathymetry Grid North Perth Survey CustodianCustodian: Geoscience Australia Jurisdiction: Australia DescriptionAbstract: The North Perth Survey was a Geoscience Australia survey run by the Energy Program. The Chief Scientist was Dr. Andrew Jones. This record includes data products from the bathymetry data collected. The products are an overall GeoTIF, an xyz ASCII grid, a CARIS csar grid and an ESRI Raster grid. All products are gridded at 20m resolution and projected to WGS84 UTM zone 50S. A short report with some processing details is also included with the data. ANZLIC search words:

Free Data DownloadData qualityLineage: Products generated from orginal dataset collected. Data processed on board vessel and in the office. Some processing details: On Vessel 1. Instruments on board the vessel were in calibration. All instruments are permanently installed. A multibeam calibration was not considered necessary. Early survey results over targets indicated previous calibration was sufficient. 2. Sound Velocity Profiles were taken on board daily and added directly into the SIS acquisition software. 3. Vessel and Instrument offsets were input into SIS acquisition software. This is a setup on board the vessel. 4. Data collection was monitored and depth `mode? adjusted accordingly. 5. After data collection the raw.all files were transferred onto a shared drive and loaded into CARIS HIPS&SIPS software. 6. Fieldsheets were created at suitable resolution, data was swath edited and then subset edited. 7. Some data exports were made on the vessel for project needs. Off Vessel 1. Remaining processing was completed. 2. Fieldsheet BASE surfaces were created using CUBE. 3. Gridded surface products were generated from CARIS HIPS&SIPS including an xyz ASCII and geoTIF. 4. The xyz ASCII was used to generate a Raster using ESRI ArcGIS. Positional accuracy: The RV Southern Surveyor used a DGPS and several GPS receivers with an accuracy of approximately 1m. Attribute accuracy: Attribute accuracy varies with depth but calculated uncertainty varies from 0.5m to approximately 6m. Logical Consistency: Visual assessment of the grids indicates that its logical consistency is good. Completeness: All accepted points were used to contribute to the CUBE surface used in processing. These grids include the entire survey. Contact information
