I don't understand why mappers in Zeeland are considered less reliable than those in South Holland? Isn't all of the Netherlands below sea level, consisting entirely of polders and dykes? ;-) (Just joking... I know there are hills some tens of meters above sea level...)
http://overpass-turbo.eu/s/QyU - hedge ways in South Holland (1011) http://overpass-turbo.eu/s/QyT - hedge closed ways in South Holland (137) - <14% of ways http://overpass-turbo.eu/s/QyS - hedge closed ways with area=yes in South Holland (91) So in this case there is a 2:1 ratio of those with area=yes vs without, unlike in Zeeland - but the total numbers for ways and closed ways are both slightly lower than those for Zeeland (where there are 1179 ways, 146 closed). I checked The Haag and Rotterdam, since it has been suggested that we should look at mapping in towns and cities. There are 3 places with area=yes hedges in Rotterdam. One is here, where several plantings of bushes(?) spell out "ROTTERDAM" next to a highway: https://www.openstreetmap.org/way/325978680#map=19/51.91438/4.53259 - note that the multipolygon hedges like https://www.openstreetmap.org/relation/4550190 do not have area=yes. I think it is a stretch to use "barrier=hedge" for a purely ornamental, low-height planting like this. The other place with more than one hedge is in this cemetery. https://www.openstreetmap.org/way/550331809#map=19/51.87471/4.50668 In The Haag the main place was these hedge areas by the Vredespaleis ("Peace Palace"?): eg http://www.openstreetmap.org/way/665101476 But they are tagged area=yes + barrier=hedge, even though they look like this: https://www.alamy.com/stock-photo-beautiful-garden-of-the-peace-palace-or-vredespaleis-in-dutch-which-104165268.html Those are short linear hedges, about 1/2 meter wide, around a garden flower bed. It is not a solid area of hedge, so area=yes is misleading. There are also some thin, 1 to 2 meter wide linear hedges along some roads to the north of this palace, eg: http://www.openstreetmap.org/way/291963185 The current rendering looks the same as before for these at z16 to z18, since they are too narrow to see any gap between the lines: https://www.openstreetmap.org/way/291963185#map=18/52.10004/4.29410. At z19 a small gap between the lines is just visible: https://www.openstreetmap.org/#map=19/52.10017/4.29383 - So there is little advantage from mapping this feature as an area for rendering maps at most zoom levels, though it might make a visible difference at z20 and higher. Using the `width=` tag would be a reasonable alternative. Overall, even in South Holland it is rare to map hedges as an area instead of as a linear feature, and there are a number of hedges mapped as areas which lack area=yes, and some hedges with `area=yes` that are not actually area features. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
