The geography is real. Nothing else is.

The ledger

Three datasets, preloaded

Fourteen files, 149,270 features, 54,117,848 bytes. All of it ships inside the product and draws with the network switched off. Two of the three carry an attribution obligation; the third explicitly does not, and saying so is part of recording it — an attribution nobody owes, presented as a duty discharged, is decoration.

The exception

One source is requested, not shipped

The Basemap layer draws its tiles from OpenFreeMap, over OpenStreetMap data. The product's own coverage counter groups it with roads and lot size, and on the axis that counter draws — real against invented — it belongs there. On every other axis it is the odd one out, and this is where the other axis gets stated.

• It is off until a reader turns it onTicking the layer requests nothing. It opens a gate carrying the cost, and the engine is not imported until that gate is answered.Opt-in
• The choice persistsOn a later visit it has already been answered, so tiles are requested during page load without a second press — until it is withdrawn.Stated
• The cost is recorded in the product's own words“Every reader's IP and viewport reach a third party on every map view.” Self-hosted tiles were the alternative offered, and were not chosen.Accepted
• ODbL, and the credit is structuralThe rendered line is © OpenFreeMap © OpenMapTiles © OpenStreetMap contributors, ODbL, minted by the same call that builds the map. The engine refuses to construct against a container with no credit registered.Required

What is not established: whether OpenFreeMap's free service permits public commercial use at the volume a deployed site would generate. The review that recorded the attribution requirement read the provider's published terms and did not contact the provider, and says so in its own record. Nothing here should be read as that arrangement being cleared.

Coverage

Where it stops, as a number

The board renders this table on a panel marked REQUIRED that a reader cannot switch off. It is reproduced here because a page describing the board should not be vaguer than the board.

The last row is the one that matters most and it is the one a coverage table usually omits, because coverage tables are written about the data a product has.

New Zealand

Region outlines, and nothing finer

Eight of the thirty-two subjects are New Zealand, served from the same board and the same contracts as the Australian twenty-four. What they do not have is geography below region level: no postcode polygon, no suburb, no road centreline, no lot.

There is no official open postcode-polygon set — NZ Post licenses the Postcode Network File commercially. But postcodes were never the only option. LINZ layer 113764 “NZ Suburbs and Localities” publishes around 6,500 suburb and locality polygons under CC BY 4.0 with commercial use permitted, verified 2026-08-04. New Zealand subjects have city-level geography only because that dataset has not been ingested, which is a choice not yet made rather than an absence of data.

Adapted from SOURCE.json, the product's own geography record

The regions that do render are real: Natural Earth admin-1 supplies 30 features, Auckland, Bay of Plenty, Canterbury, Hawke's Bay, Wellington, Waikato and Otago among them. And a currency note that belongs beside any New Zealand figure: all eight NZ subjects are denominated AUD. The product holds no NZD values, so nothing here is shown in local currency.

A decision, recorded

Why the preloaded layers avoid ODbL

Public domain was chosen over OpenStreetMap-derived boundaries deliberately. ODbL requires visible attribution and imposes share-alike on derived databases, which would bind the product; Natural Earth imposes neither. No attribution string is rendered for it because none is owed.

If that conclusion is ever wrong, the obligation appears suddenly, so it is recorded here rather than assumed.

The same record, on its own reasoning

Read that against the section above and the tension is the point: the preloaded geography avoids ODbL, and the optional basemap accepts it. Two opposite calls, both written down, made for different layers under different constraints. A product that recorded only the convenient one would be easier to describe and worth less.
