I suppose topo maps will follow this demise. In 2019, NOAA announced its Sunsetting of Raster Nautical Charts in the Federal Register. The raster sunset program will gradually end production and maintenance of NOAA traditional paper and raster nautical chart products. Beginning in 2021, NOAA will start canceling its traditional nautical charts. The process is expected to be completed by January 2025.

Perhaps. I've noticed at this site that USGS maps are being updated -- but they are digitally drawn, so some information from ye olde days aren't on there any more: https://ngmdb.usgs.gov/topoview/viewer/#15/48.1117/-121.1130

The Terrain map view here is a vector map, which is what all the marine maps will be. The USGS Topo view looks like a scanned image.

Doesn't really bother me. The NOAA charts and USGS maps aren't really artistic, so "vector" representation makes sense. Doesn't stop people or companies from deriving printed maps from the latest data. The contour lines on the existing maps are the most interesting aspect though, whether those are considered authoritative and preserved in the vector dataset, or whether digital elevation grids are the authority and end users are responsible for inferring contours.

Did you click and view the 2020 Glacier Peak quad? It's also a vector map, but it's been updated since 2017 (well, there's a 2017 version at any rate). Then look at the 1999 map, which is clearly a raster image. it's fun to look at the 1950 and 1901 topo maps available on the USGS site, or all the others available.

I haven't bought a paper map or chart for at least a decade, possibly more. But I developed GIS systems in the early '90s for a startup and once I could print scanned USGS topo maps and noaa charts on a laser printer, I lost interest in buying paper maps.

NOAA has two versions of GIS marine charts. Open the list of basemaps and look at the last 2 entries.

The National Map viewer is what you want. Retains all the labels (well most of them that I've seen, I'm sure there are some that have been trimmed), but it's vector based so it scales much better.
