I think it is OK when you add a comment like
# assume that a closed way with highway=pedestrian is meant to
describe an area even if area=yes is missing

Betreff: Re: [mkgmap-dev] default style improvements
Hi
Reading some of the relevant wiki pages, I am finding the wording
ambiguous.
It seems wrong that the handling of the area= tag is not consistent
between polygons generated from closed ways and those generated by
multipolygon relations, but, if you assert that it is, I'll respect
it.
Regardless, there are a lot of Piazzas that are not generated from a
multipolygon and don't have the area tag, eg
My 'polygons' change as it stands:
highway=pedestrian & area!=no [0x17 resolution 22]
will show these as piazza, along with other areas that might not be.
If I change it to:
highway=pedestrian & (area=yes | mkgmap:mp_created=true) [0x17
resolution 22]
it won't show them.
Which is preferred?

It's not what I meant.
The example you provided is a multipolygon relation and
multipolygons
are always areas regardless if area=yes is set or not.
So this is not a valid example, actually I can not find one really
evident of missing area=yes on pedestrian areas.

Hi
I don't see anything in the OSM definition of a square that
requires
it
to come from a multipolygon relation

Hi Lorenzo
I know that the OSM definition says square should have
area=yes,
but
I
find a vast number where there is no area tag and they seem
to
be
square/piazza, eg
This is a multipolygon.
The current rule to handle this with the mkgmap:mp_created tag
is
fine
for a default style in my opinion.
With Italy data from July 2018, I get about 5000
highway=pedestrian
polygons without an area tag, and, from a small sample, about
1
in
3
look like piazza.
The only effect is that a polygon is generated, it doesn't
effect
routes. I prefer to see the possible square rendered.
I don't. 1 in 3 correct is not so good :)
