Hi Tomas,
You do realize the 1-2 years is well after the 2013 date that the Dutch
Kadastre started to publish their work?
As to Lithuania, I can't speak for your country, but your Swedish Baltic
brethren actually adopted the Dutch Kadaster's approach, including the
developed models through a cooperation agreement:

Maybe your Lithuanian cadastre looked over the shoulders of the Sweeds?
At the very least, they may have gotten a little inspiration... ;-),
although they may well have developed this entirely on their own using
the same ESRI tools. For sure, the Dutch Kadaster seems to have been
very open about their specific development work in an international
context...

However, as to interesting stuff to read: our national Kadaster of the
Netherlands, is actually the very first and only national mapping
organization world wide, that has successfully managed to implement a fully
automated generalization work flow for generating 1:50k maps from 1:10k
maps, including landuses, waterways, highways, but also generalizing
build-up areas and buildings. They used a range of cartographic
generalization tools from ArcGIS (that I didn't use...).
Congratulations to national Kadaster, but I'm not sure you're
correct about "first and only". Our local (Lithuanian) land agency (or
to be more specific gis-centras) has completed automated
generalisation 1-2 years ago (using esri tools as well). As far as I
know fully automated and done in ~day.
Most GIS people use a work by Sandro Savino "A solution to the
problem of the generalization of the Italian geographical databases
from large to medium scale: approach definition, process design and
operators implementation". Author claims to have completed automated
generalisation for Italy and it dates to 2011. This work is very
interesting because instead of referring to closed commercial tools it
has a very detailed description of how to actually do this and that.
Also Swiss Topo is known to be doing a very high quality
generalisation for years(?).
But thank you for your links, it is interesting to learn how
different countries handle generalisation.
