Hi, first, thanks for a fine research tool. It's been very useful. Second, where does the info that makes the maps come from? I'm doing some research into my local park and wondered where the information about the boundaries came from? http://www.openstreetmap.org/#map=17/55.80147/-4.37698 asked 09 Aug '13, 20:45 focphelp |
You can tell the user ID of the person who did the edits and when they did them. On the left side of the map is a layers icon. Clicking on that will show a check box for data. You can see the various items and select individual ones to get more information about it. For example Cowan Park shows, among other things: History for Cowan Park Details
With JOSM (and maybe other editors but I mostly use JOSM) the object's edit history is also available and you can look at things like the check-in comment which, for the latest "drnoble" edit, is "Around Cowan Park, Barrhead from GPS survey/bing". So there you have it - GPS combined with Bing imagery. There are web tools for looking up information about the contributors and where else they've made contributions. You can then contact the contributor and clarify where they got the information from if they haven't been as descriptive as you'd like with the "source" key value. answered 09 Aug '13, 21:05 n76 Frederik Ramm ♦ 1
"On the left side of the map"? The "other" left? Also, if you have the History shown above you can click "Details" to see the details of what nodes and what tags made up each version of the way. From there you can click on the relevant changeset id to see the check in comment, e.g. http://www.openstreetmap.org/browse/changeset/14295056
