Lake Michigan, Mercator Projection

Historical chart: Lake Michigan (Mercator Projection), held by NOAA Office

Lake Michigan (Mercator Projection) Lake Michigan (Mercator Projection) (2024), Nautical Chart, scale 500000.

Visual descriptionwritten by a machine · unchecked

A vertically oriented nautical chart shows a large blue water area bordered by detailed shorelines, with numerous depth soundings, navigation symbols, route lines, and place labels. Compass roses, coordinate grids, explanatory notes, a scale bar, and a small inset diagram appear around the margins.

A model wrote this. It was shown the image and the catalogue record together, and asked to keep them apart — what it saw is here, what the record told it is under "taken from the record" below. It is still wrong often enough to matter, about who is pictured, where, when, and what is happening. Read it as a way to find the image, never as evidence about it. If you can correct it, please do: write to michael.bommarito@gmail.com, or see how corrections work. Someone who recognises a face or a shoreline knows more than the model did.

Rights and credit

Public domain (NOAA Office of Coast Survey)

Credit this to NOAA Office of Coast Survey when you use it.

Material goes off the web without anyone deciding that it should: a host lapses, a gallery is retired, a link stops resolving. Holding a copy — with its provenance, its checksum and its holder's terms recorded beside it — is much of why this archive exists. If you are looking for something whose original has since gone, write to michael.bommarito@gmail.com and a full-size copy of what is held here will be sent to you.

Recorded verbatim from the provenance sidecar taken at retrieval — this archive does not restate a holder's terms in its own words, does not add a restriction the holder did not state, and does not abridge one.

The archive holds its own copy of that file and will supply it on request; it is not re-served here, because the holder serves it better and a second copy is a second thing to go stale.
