Places
Somewhere to drop the anchor.
This section is heading for one page per anchorage, marina, port and fuel dock. None of them are on the website yet, though they are already on the chart in the app: the bays, the mooring buoys, the fuel docks and what is ashore around each of them.
What a place page will show
The facts the chart already carries.
Laid out for one place, and linked to the region around it.
- Depth and the bottom around it, from the open hydrographic models — EMODnet, NOAA, AusSeabed, LINZ and GEBCO — whichever covers the water you are looking at.
- Tide height on arrival, and the depth in the anchorage corrected for it, in the regions where tides matter.
- Mooring buoys, fuel docks and facilities, with the hazards, restrictions and fish farms around the bay.
- Seamarks and lights with their light characters, for example Fl(2)R.10s7m8M.
- Ashore: restaurants, drinking water, shops, beaches, pharmacies, ATMs and ferries.
- The region it sits in, so the local conditions, the weather model and the official warning service for it are one link away.
The map is a planning aid, not an official nautical chart.
Where it comes from
Open data, not a private database.
Most of what Bonasea knows about places comes from OpenStreetMap, mapped by people who were actually there.
Depths come from the open hydrographic models, the tiles from OpenFreeMap, and the bays, buoys, fuel docks and shore amenities from OpenStreetMap. In the priority regions we add and curate places ourselves on top of that. It is the same reason there is no chart subscription and no per-region purchase: the data underneath is public.
A bay is missing, or wrong.
Write to us and we will look at it. Most of the time the fix belongs in OpenStreetMap, where correcting it reaches every chart that uses the data rather than only ours — and in the priority regions we do the curated additions ourselves.
