Sources, accuracy and updates
Where this data comes from
The atlas is the reference data behind Dhuveli, the vessel tracking platform we build in Maafushi. It is what our maps use to turn a GPS position into a sentence a person can read — “alongside in Malé harbour” rather than a pair of numbers. We publish it because it is more useful shared than kept.
Sources
Maldives Land and Survey Authority
The island register — 1,134 named islands with their official positions, land codes, categories and areas — and the surveyed outlines of 2,515 reefs, 1,190 lagoons and 93 protected areas. Published through OneMap. Protected areas are designated by the Environmental Protection Agency.
OpenStreetMap contributors
Harbours, jetties, ferry terminals, anchorages, dive sites, wrecks, navigation lights, beacons, buoys, airports and landmarks — mapped by people on the water and on the islands. Licensed under the Open Database Licence 1.0; anything you take from us that came from OSM carries that licence with it. Re-imported monthly, so a fix made at openstreetmap.org arrives here on its own.
Maldives Fisheries Information System
Fish aggregating devices and ice plants, from the registers the Ministry of Fisheries and Ocean Resources publishes at keyolhu.mv — capacity, operator and contact for each plant, and the bearing and distance that names each FAD. Refreshed daily. Where the register’s own coordinates put a plant in the wrong place, we geocode it from its island name instead and say so.
Using it
Read it, link to it, quote it — that is what it is here for. If you need the data itself for something you are building, or live vessel positions rather than fixed places, get in touch at info@oneconnect.mv; there is also the Dhuveli API.
Anything here that came from OpenStreetMap is available directly from openstreetmap.org under the Open Database Licence, and the survey layers are published by the Maldives Land and Survey Authority through OneMap.
How accurate is it?
Good enough to find a harbour entrance, name an anchorage, or plan a route between islands. Not good enough to navigate on. Island positions come from a national survey and are reliable; a dive site is wherever the diver who mapped it dropped the pin, and can be a couple of hundred metres out; a FAD is anchored in deep water and moves within its scope.
This is not a navigational chart and must not be used as one. Use official charts and your own eyes.
Report a correction
Something wrong, missing, or in the wrong place? Email info@oneconnect.mv with the page and what you know. Local knowledge is the only way a reference like this gets better, and corrections from people who actually work these waters are the ones we act on fastest.
If the place came from OpenStreetMap — the source is named at the bottom of every page — you can also fix it there directly, which helps everyone using that data, not only us. It reaches the atlas at the next import.
How often it updates
- Daily — FADs and ice plants from the fisheries register.
- Weekly — the survey outlines: reefs, lagoons and protected areas.
- Monthly — harbours, dive sites, navigation marks and everything else from OpenStreetMap.
- As it happens — corrections we make ourselves.
