<div dir="auto">I agree with Kathleen. Given that smartphones are more common than internet connected computers and it is easier to add or change tags on a smartphone than add a long highway at least the locals stand more chance this way.<div dir="auto"><br></div><div dir="auto">Cheerio John</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Jul 29, 2019, 1:00 PM Kathleen Lu via talk, <<a href="mailto:talk@openstreetmap.org">talk@openstreetmap.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>On the other hand, if the map of your area is completely blank, it looks very daunting to a new mapper, who may be discouraged and abandon OSM (either as too difficult to improve and as too poor quality to use).</div><div>The map is constantly changing because roads and other things on the map are changing in the real world.

<br>
I'm not certain this is true. It might be very difficult to find the<br>
1% of incorrectly mapped roads; you don't know where to look, and you<br>
must survey on the ground with GPS, and check each road segment to<br>
find the 1% that actually are blocked by a fence or gate or don't<br>
really go through that clump of trees.<br>
<br>
In contrast, when 99% are missing it's very obvious when looking at<br>
the map data. You still have to survey and add the streets, but it may<br>
actually be faster to get to a complete map of your home neighborhood,<br>
than trying to find 10 bad streets out of 1000 segments in your<br>
neighborhood.<br>
<br>
Finally, when you look at the map and it looks 100% complete, you<br>
won't see the need to start mapping and become a totally addicted<br>
OSMer like you will if your village is only 1% mapped, so we may not<br>
get the new contributors that we need to actual maintain the data that<br>
our robot mappers have added.<br>
