<div dir="ltr"><div>Hi,</div><div><br></div><div>I never knew this existed, but apparently you can use place=square to mark squares (NL: plein, FR: place). As explained below, current mapping practice make for some ambiguous situations, which can be avoided using this tag. Use is rising very quickly since mid 2015.</div><div>Any reason for not using this in Belgium? (only a few are mapped, in Brussels)</div><br><div class="gmail_quote">---------- Forwarded message ----------<br>From: <b class="gmail_sendername">mbranco</b> <span dir="ltr"><<a href="mailto:mbranco2@gmail.com">mbranco2@gmail.com</a>></span><br>Date: 2017-01-02 13:16 GMT+01:00<br>Subject: [OSM-talk] Square (Place, Platz,Piazza, Plaza, …)<br>To: <a href="mailto:talk@openstreetmap.org">talk@openstreetmap.org</a><br><br><br>Following are personal thoughts, I'd like to discuss them and discover if it<br>
could be a general issue (not only for my country, Italy).<br>
<br>
*Premise*<br>
<br>
- Squares are urban areas, whose perimeter is drawable with a single<br>
closed way.<br>
- These areas have an official name.<br>
- The old and very basic paper maps show always at least two elements, for<br>
towns/cities: streets and squares (and related names, if they are big enough<br>
to show them too).<br>
- Inside square areas there could be a lot of different things: highways,<br>
monuments, buildings, flowerbeds, … : attributes of the square must refer to<br>
all the area, not only a part (relevant or not) of it.<br>
- I prefer think that practicability could be one of the (optional)<br>
attribute of a square, not the opposite: square is not an (optional)<br>
attribute of the practicability --> i.e. highway=pedestrian + area=yes .<br>
- highway=pedestrian + area=yes could not mean “square”: there are a lot<br>
of pedestrian areas, for example in parks, that are not squares.<br>
- Practicability inside a square is fully described by all the highways<br>
inside it, the two kind of information (for square and for practicability)<br>
can be fully disjointed (for the square with nothing inside and fully<br>
pedestrian, the square area and the pedestrian area coincide).<br>
<br>
*Request*<br>
<br>
Please render the place=square tag (or a new tag, whatever you prefer).<br>
/<br>
“Place” is already widely used (and rendered) for urban areas: borough ,<br>
suburb, quarter, neighbourhood, city_block, ... ; it’s not widely used for<br>
squares because it’s not rendered!/<br>
<br>
*Hints*<br>
<br>
- Maybe rendering could use a semi-transparent color and square name could<br>
be evidenced, as it’s already done e.g. for landuse=military [1] (a common<br>
landuse in urban areas).<br>
- Names of the highways inside the square which are identical to the name<br>
of the square could be omitted [2] (just only in the rendering, of course).<br>
- Another example of possible rendering is here [3] .<br>
<br>
<br>
*<br>
Hopes*<br>
<br>
- Mappers could avoid to put highway=pedestrian + area=yes in squares like<br>
this one [4] .<br>
- Mappers which don’t like the previous solution but nevertheless think<br>
that it’s useful to read the square name in the rendering, could stop to<br>
assign arbitrarily the square name to the marketplace, or to the parking<br>
area, or to the flowerbed, or to any other item inside the square [5].<br>
- Extraction tools as Osmfilter or Overpass could do selections related to<br>
squares, street-guide tools as MapOSMatic could produce better outputs.<br>
<br>
Thank you for your attention, cheers and Happy New Year!<br>
