I do see your point regarding lacking information in papers.
Truth to be told, most labelling research is from computational geometry 
and they do often not care too much about actually labelling the maps, 
weird as it sounds. And as a more math-based discipline, they have a 
very low priority on providing workable parametrisation. Exceptions 
exist of course, no disrespect whatsoever to all the brilliant geometers 
out there on whose shoulders we stand!

Our paper in contrast includes all the information and parametrisation 
you need to implement that wherever you want. And the tileset shows you 
how the results will look like.

Maybe we should have waited till the paper is accepted before sharing. 
Sorry for any confusion we caused.
Thanks for your interest and time.


PS: Regarding government money on research
We all have limited contracts and are evaluated by journal paper output. 
That is the reality of it. Our boss is a strong believer in "demo or 
die", but the general structure works against that.
