The new Elevate 4.2.0 includes now bBoxWeight for islands and archipelagos, too.

Update for the european maps should be online on monday.
Unfortunately every new Mapsforge/Osmosis version needs more and more resources for building maps.October 7, 2017 at 11:21 #20515

In the beginning of mapsforge V3 I was able to render even the (real big) Alps.map with a heap of 2,6GB on my 32bit Notebook.
Now I need a heap of 5GB for this map otherwise I run OutOfHeapSpace.
Dont get me wrong – I don’t complain, there were tons of improvements like much better handling of faulty polygons, there are no longer white tiles in the maps, aso..
However, its a fact that rendering 5-6 maps in paralles on a machine with 32GB RAM is max – while in the beginning 8-9 maps were possible.
… and on my mainboard 32GB is the limit …
So rendering of europe now takes at least 8 days + 2 days for Germany (incl all preprozessing, w/o contourlines,w/o land/sea)
Again, no complaint just a fact and in general its my experience for over 30 years that every new version of an environment (java,osmosis, aso in this case) needs more an more resources.

@ChristianK – I think there are some other factors that changed since then – we added a lot of stuff in tag-mapping, things like bbweight as well, better contour lines, and of course there’s now much more OSM data to process because of all those busy mappers…

we added a lot of stuff in tag-mapping,
Yes, of course.
And V3/V4 maps in parallel (this does’nt effect RAM consumption but rendertimes), and better 1′ contourlines for many regions, and..
In the end – the rendermachine is on its absolute limits.
BTW: The new European maps are online, only Scandinavia_North and Ukraine V4 is missing.
So testing of themes is possible now.
