Hello,
on Osmarender I once implemented rendering of rivers, stream, canal,
etc. in their real width. A Cartographer once told me that unlike
roads waterbodies are usually drawn in their real extent on maps
after all.
With Osmarender beeing abandoned now, there will soon be no map
available
So, talking about Mapnik2, ist there a way fo a data-driven control
of stroke-width in LineSymbolizer.
no. But you can always use SQL as ultimate scripting language for
mapnik, writing something like:
select
ST_Buffer(way,
coalesce((CASE WHEN (tags-'width') ~
