<body class='hmmessage'><div dir='ltr'>Hi Andy,<br><br>yes, I contacted some editors and typically got positive feedback,<br>so it is clear to me that nobody intended to create unusable data.<br><br>I just don't understand why iD offers a method to combine elements<br>when this is such a tricky thing. Why would a "beginner" need that?<br><br>ciao,<br>Gerd<br><br><div>> To: dev@openstreetmap.org<br>> From: ajt1047@gmail.com<br>> Date: Tue, 13 Oct 2015 13:02:34 +0100<br>> Subject: Re: [OSM-dev] iD creates invalid (?) highway tags<br>> <br>> On 13/10/2015 09:03, GerdP wrote:<br>> > Hi all,<br>> ><br>> > I wonder why iD allows to create ways with e.g.<br>> > highway=primary;service<br>> > or similar combinations?<br>> ><br>> <br>> Whilst there are technical things that editors can do (P2's visual <br>> indication shows that semicolon values are "wrong" is one example), it's <br>> not really a technical problem.<br>> <br>> New mappers that create something like "highway=primary;service" do so <br>> because they don't really understand what they're doing yet. It's not <br>> obvious to new mappers that a road called "High Street" needs to be <br>> split into several sections if part is primary, part residential and <br>> part something else. The only way they're going to find out is if <br>> something that they see before they start mapping explains this (tricky, <br>> because it's a bit of an information overload if all they want to do is <br>> add e.g. a node for a POI).<br>> <br>> Also, it's not always possible to pick things like this up within the <br>> editor at all; for example merging a "highway=residential; <br>> sidewalk=both" with a "highway=residential" that doesn't yet have the <br>> sidewalk surveyed. Did the mapper survey the missing sidewalk or merge <br>> it my accident?<br>> <br>> What we're going to have to keep doing in these cases is spotting new <br>> mappers and helping them when they get it wrong*. Editing OSM is <br>> complicated, especially in detailed urban areas or where a previous <br>> mapper or import was over-heavy on the multipolygons.<br>> <br>> Cheers,<br>> <br>> Andy<br>> <br>> * which a quick scan of http://resultmaps.neis-one.org/osm-discussions <br>> suggests that you're doing already a _lot_, so thanks very much for that!<br>> <br>> <br>> <br>> <br>> _______________________________________________<br>> dev mailing list<br>> dev@openstreetmap.org<br>> https://lists.openstreetmap.org/listinfo/dev<br></div> </div></body>
