are of course now also "electronic", as they are made from a digital source. If you buy digital raster charts
these are not paper charts run through a scanner. It's the other way round. Paper charts are digital charts printed on paper...
I remember a visit to the geographic office in Belgium when I was a student. The guide told us then (this was 1990) that what they produce there is a database. The database is used to produce, amongst other things, paper maps. Maps are produced on a computer, but producing maps does still involve a human being, to decide what to show, and what not to show at each scale.
I remember my professor telling us that if you'd manage to design a computer algorithm that can do what a skilled cartographer does you'd retire young and very rich...
The main difference between "vector" and "raster" maps is the human element. They are actually both digital, both the product of a entirely digital workflow. And both end up as bitmaps on a screen
... But in case of a "raster" map a skilled cartographer has made the decisions what to show at what scales.
And that is probably also why conventional, raster maps are considered more aesthetically appealing. They are more consisten, and convey the needed information well.
I use on my iPad
the Imray charting application. Imray raster charts are beautiful, and if apple ever makes a table twice the size of an iPad
I'll be in heaven. So for me it's digital "paper" on an iPad at the moment, combined with whatever I find on board the boat
