Australian Notices to Mariners Editions are the authority for correcting Australian Navigational Charts and Australian Nautical Publications and are published fortnightly by the Australian Hydrographic Office. Australian Notices to Mariners are numbered from 1 onwards and are published in 26 fortnightly editions each calendar year.
The AHS has been publishing paper nautical charts since 1942. They are relied upon and trusted by Australian and international commercial vessels, recreational The Australian Hydrographic Service (AHS) publishes and updates approximately 450 official paper nautical charts providing coverage of the Australia Charting Area. The AHS releases its paper chart coverage under the 'Aus' series. It includes Australian, Papua New Guinea, Timor Leste and Australian Antarctic Territory waters.
AusENC are official vector Australian Electronic Navigational Charts (ENC) providing coverage of Australian and Papua New Guinea waters.
They are authorised for use in IMO compliant Electronic Chart Display and Information Systems (ECDIS) and can also be used in compatible Electronic Chart Systems (ECS).
ENC deliver additional functionality over paper or raster charts when used in an ECDIS or suitable ECS. This additional functionality includes:
The Intertidal Extents Model (ITEM v1.0) product is a national scale gridded dataset characterising the spatial extents of the exposed intertidal zone, at intervals of the observed tidal range. The current version utilises all Landsat observations (5, 7, and 8) for Australian coastal regions (excluding off-shore Territories) between 1987 and 2015 (inclusive). The Intertidal Extents Model (ITEM v1.0) consists of three datasets derived from the Landsat NBAR data managed in the Australian Geoscience Data Cube (AGDC) for the period 1987 to 2015.
Water Observations from Space (WOfS) is a web service displaying historical surface water observations derived from satellite imagery for all of Australia from 1987 to present day. WOfS aims is to allow better understanding of where water is usually present; where it is seldom observed; and where inundation of the surface has been occasionally observed by satellite. WOfS displays the detected surface water from the Australia-wide Landsat 5 and Landsat 7 satellite imagery archive.
For each grid cell within the map, WOfS displays:
Sentinel hotspots are derived from Moderate Resolution Imaging Spectroradiometer (MODIS) sensors on board Terra (morning pass) and Aqua (afternoon pass) satellites. Images are captured, over a given point at least four times a day, between the two satellites, each with a ground swath of 2330 km and day/night coverage.
The Fractional Cover (FC) algorithm was developed by the Joint Remote Sensing Research Program and is described in described in Scarth et al. (2010). It has been implemented by Geoscience Australia for every observation from Landsat Thematic Mapper (Landsat 5), Enhanced Thematic Mapper (Landsat 7) and Operational Land Imager (Landsat 8) acquired since 1987. It is calculated from surface reflectance (SR-N_25_2.0.0).
The full SENTINEL-2 mission comprises twin polar-orbiting satellites in the same orbit, phased at 180° to each other. The mission carries optical sensors and monitors variability in land surface conditions.
The main objective of the SENTINEL-3 mission is to measure sea surface topography, sea and land surface temperature, and ocean and land surface colour with high accuracy and reliability to support ocean forecasting systems, environmental monitoring and climate monitoring.
