Marine Benthic Substrate Database - CAMRIS - Marsed
This database contains information about the distribution of 10 different types of sea floor sediment in the Australian region. It was derived from data collected and mapped by the Ocean Sciences Institute, University of Sydney.
External accuracy: +/- one degree.
Non Quantitative accuracy: Data are... more assumed to be correct.
The item called SUBSTRATE describes 9 classes:
Biosiliceous marl and calcareous clay;
Calcareous gravel, sand and silt;
Mud and calcareous clay;
Mud and sand;
Sand, silt and gravel with less than 50% mud;
Volcanic sand and grit.
Conceptual consistency: Coverages are topologically consistent. No particular tests conducted by ERIN.
Completeness omission: Complete for the Australian continent. less

ERIN: Data were projected to geographics using the WGS84 datum and spheroid, to be compatible for the Australian Coastal Atlas.
Ocean Sciences Institute extracted the data from the AUSEABED database, and sent to CSIRO.
All CAMRIS data were stored in VAX files, MS-DOS R-base files and as a microcomputer dataset accessible under the LUPIS (Land Use Planning Information System) land allocation package. CAMRIS was established using SPANS Geographic Information System (GIS) software running under a UNIX operating system on an IBM RS 6000 platform. A summary follows of processing completed by the CSIRO:
1. r-BASE: Information imported into r-BASE from a number of different sources (ie Digitised, scanned, CD-ROM, NOAA World Ocean Atlas, Atlas of Australian Soils, NOAA GEODAS archive and The Complete Book of Australian Weather).
2. From the information held in r-BASE a BASE Table was generated incorporating specific fields.
3. SPANS environment: Works on creating a UNIVERSE with a geographic projection - Equidistant Conic (Simple Conic) and Lambert Conformal Conic, Spheroid: International Astronomical Union 1965 (Australia/Sth America); the Lower left corner and the longitude and latitude of the centre point.
4. BASE Table imported into SPANS and a BASE Map generated.
5. Categorise Maps - created from the BASE map and table by selecting out specified fields, a desired window size (ie continental or continent and oceans) and resolution level (ie the quad tree level).
6. Rasterise maps specifying key parameters such as: number of bits, resolution (quad tree level 8 lowest - 16 highest) and the window size (usually 00 or cn).
7. Gifs produced using categorised maps with a title, legend, scale and long/lat grid.
8. Supplied to ERIN with .bil; .hdr; .gif; Arc export files .e00; and text files .asc and .txt formats.
9. The reference coastline for CAMRIS was the mean high water mark (AUSLIG 1:100 000 topographic map series).

CAMRIS, standing for the Coastal and Marine Resources Information System, is a small-scale spatial analysis system developed in collaboration by several divisions of Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO), as part of the CSIRO Coastal Zone Program. CSIRO Division of Wildlife and Ecology was the custodian of... more the 'coastal' subset of the Australian Resources Information System (ARIS). Coastal ARIS became the core dataset of the CAMRIS project. The Coastal ARIS database was developed from a coastal inventory developed by Galloway et al. This inventory contained relatively large scale data including landform, geology, vegetation, soil, land use, climate and population information for each of 3027 3x10km sections around the coastline of mainland Australia and Tasmania, but excluding offshore islands. less
