Low resolution country borders in GeoGraphics

[russell (Gareth Russell)]

In 14.3 at least, when I make a large map with any projection other than the default Equirectangular, the country borders that are overlaid by default are rough and fuzzy. Anyone else? E.g.:

GeoGraphics["World", GeoProjection -> "Mollweide", ImageSize -> 1600]

Apologies for this new bug, and thanks for reporting it. The new GeoGraphics still rasterizes the output in some projections, and it is not doing a proper job in this case, because it is not taking into account that the output will have a large image size. I can offer two alternative workarounds for it:

1. Prevent rasterization. Try this:

   GeoGraphics[“World”, GeoProjection → “Mollweide”, ImageSize → 1600, Method → {“VectorMapRasterize” → False}]

2. Intercept the rasterization process and increase the image size. Try this:

   AppendTo[SystemGeoStylingDump$VectorRasterizeOptions, ImageSize → 1600];
   GeoGraphics[“World”, GeoProjection → “Mollweide”, ImageSize → 1600]

The quality is then better in either case:

Thanks! I like that these workarounds reveal little hints about what is going on under the hood…
