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?
