Bathymetry — AusSeabed (Geoscience Australia)

The bathymetry data shown in BayCast (depth contours, sea-floor relief, the REEDY PRO HD 3D rendering) is derived from compilations published by AusSeabed — the national seabed mapping coordination programme led by Geoscience Australia.

AusSeabed itself states clearly that this data is not suitable for marine navigation:

"The data sets are not suitable for use in marine navigation or in the creation of navigational products or any other purpose involving safety at sea."

BayCast displays this data for fishing trip planning at home only. For navigation, use approved nautical charts on a proper marine GPS plotter.

Weather & tide

Forecast wind, weather and tide data is sourced from open public weather APIs (including Open-Meteo and the Australian Bureau of Meteorology). It is provided "as is" — see Terms §5.

What this means in plain English

• The map data inside BayCast is not owned by BayCast. It is publicly licensed by the Australian and EU governments and the OpenStreetMap community.
• We render that data inside our own software so you can use BayCast's tools on top of it.
• Your BayCast Pro subscription pays for our software tools and our ongoing development — not the map data.
• If a data source updates its licence, ages out, or is replaced, your subscription is unaffected because you weren't paying for that data in the first place.
• None of this data is approved for navigation. Don't navigate with BayCast.
