Hi Reading some of the relevant wiki pages, I am finding the wording ambiguous. https://wiki.openstreetmap.org/wiki/Key:area https://wiki.openstreetmap.org/wiki/Tag:highway%3Dpedestrian https://wiki.openstreetmap.org/wiki/Area 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 https://www.openstreetmap.org/way/601220094 https://www.openstreetmap.org/way/256580148 https://www.openstreetmap.org/way/173770171 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 :)
