The real complication arises when there are shoulders of varying quality that are assessed (by cyclists) as being more or less suitable for cycling - leading to issues of subjectivity.

[Talk-us] Smooth shoulder intended for cycling
I'm wondering what the best way would be to tag a good-quality shoulder that acts essentially as an undesignated bike lane, in that you can use it but it is not required. Current Florida DOT policy is to use these on rural roads, with marked bike lanes only when there is a lane to the right. For example here: http://maps.google.com/maps?hl=en&ll=30.605358,-86.950672&spn=0.008255,0.016512&gl=us&t=m&z=17&layer=c&cbll=30.605241,-86.950558&panoid=X4-X3CdhvVO_ptMWbvB8SA&cbp=12,330.83,,0,9.24 One can choose to ride either in the right lane or on the shoulder beyond the intersection. One regional mapper uses cycleway=shoulder for this, but I see that as sub-optimal, since it's primarily a shoulder, not a cycleway. It would be like putting cycleway=sidewalk whenever there's a smooth paved sidewalk. On the other hand, shoulder=yes or shoulder=paved says nothing about the quality of the shoulder. Should there be a minimum width for a shoulder (FDOT's standard is 4 feet)? ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

In all my mapping, I see tons of bad imported data, but I see very few errors due to newbie mappers. Sometimes I'll find a mistagged feature, or an unclosed way, but overall I find users to be fairly careful, and when they're not, the mistakes they make are small and confined. Imports, on the other hand, are widespread, pervasive and are often hard to detect. I see features which are hard to verify without surveying, and I find odd OSM features, like ways that share the same geometry (even the same nodes), or duplicated features close to each other, but from different sources. Your argument that the problems are similar don't bear out in my experience mapping with OSM, the problems are neither similar in type nor scale. Nonetheless I've personally taken steps to address both. For new mappers I am very involved in helping the community. I've run mapping parties, I've made a video tutorial series, I'm active on the newbies list and (less) active on help.osm.org, and can often be found helping users on our IRC channel.

Re: [Talk-us] tiff, dwg and nad83
Regarding Frederik's 4 points, plus the element duplication issue as reasons imports are bad: ALL are potentially true for any mapper especially new ones. It is just that a bad import can generate a lot more good/bad data at once. So yes, imports need more effort to insure good quality. Regarding dupe items, this is both import related and upload related. The import side is obvious, but failed uploads of any source have generated lots of duplicates as well. This is admittedly more prone with imported data, I would guess fewer users doing manual edits tried to make large uploads. See the notes below for the rest.

Re: [Talk-us] Excellent progress, u.s.
Sure, Alan. I'll try to help by explaining a core of my process, and you and others can take it from there. Great job - thanks for this. I'm sure it helps. Appreciate the kudos. We might all share like this when asked. This is called a "workflow" and workflows with specific numbered steps are valuable/crucial nuggets of knowledge when somebody needs one to solve a specific problem AND a workflow HAS BEEN SHARED. So, ask, and, if you KNOW, share WHEN asked! 7) For ways (I'm not going to explain points), here is what I do: ... So, we're basically duplicating the existing way and then "blessing" it. Is this really sufficient - to verify the "tainted" geometry instead of re-drawing it? If so, why is it not sufficient that, in many, many cases, the original creator of the way has not accepted CT, but many other accepting mappers have afterwards aligned (i.e. moved nodes) and tagged (in my case, with sources of sat imagery, local photo survey, county records, and/or even GPS survey) it? Haven't I already "blessed" it? Can't the redaction bot look at the source tag and see this? Another point, at least in SoCal, is that many of our "tainted" ways are created by "blars", who has not accepted the CT. However, these are TIGER-imported ways. They carry the TIGER tags. I'm sure they could be verified as having come from the TIGER import. They were no-doubt the result of having split an existing TIGER way. In this case, why is it not sufficient to see the TIGER tags on the way to consider it "blessed" along with all the other TIGER ways? Especially when tagged afterwards by accepting mappers with sources as above? 8) Repeat step 7 for all bad ways (or points) in the list of "data loss" that License Problems displays. I'd like to suggest step 8.5: Run the OSM validator. It will find all the intersections that were missed, and probably a bunch of other problems that may or may not have pre-existed. 9) Upload your re-mapping efforts. I agree that a step 8.5 to run JOSM Validator is well-indicated here. Thank you for that excellent suggestion. So, can someone from the redaction squad comment on the logic being used and the questions above? I don't know that they reply to this list. I believe they read it, but I have no proof of that. Finally, it is true that my suggested workflow "duplicates an existing (tainted) way and then blesses it." Yes. The additional step of visually verifying with Bing Sat allows this to crystallize into a "solidly legal" footing: "I can see it in Bing, therefore the duplication of something which was unlicensable is now licensable." In other words, "re-drawing" is not necessary (it is sufficient), but it is overkill (unless points are also tainted). Duplication + visual inspection via Bing seems sufficient to me, but it would be really, really good to get the redaction squad to directly address that point. Right here (talk-us) would be just fine. OSM's wiki would, too. SteveA California ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

I don't disagree with your points although things get complicated in practice. I've seen people mass removing tiger:reviewed tags on any way that they happened to load into JOSM while mapping when they obviously didn't even look at it. Also, what if a user only reviewed/improved the geometry of a dirty way in one spot but the way is several miles long? This may not be the case for things you have touched but there are a lot of people who have done a lot of edits that are less rigorous. >> Unfortunately neither badmap nor OSMI fully implement all of these >> rules so yes there is still far too much uncertainty.

Won't disagree with this either. Ideally the bot code would have been developed over the past year instead of the past month and then been available to make tools like OSMI and badmap that use the actual code to show what will happen. But that's now how things happened. I'm not trying to lay blame. I've been mostly a spectator to the process myself so I'm certainly not going to throw stones.

We haven't done a questionnaire for turned-off-mappers really, and I wouldn't know how to even reach out to those who have looked at OSM and decided not to contribute. But personally, I think it's a total no-brainer. Take two equally sized cities which are mapped to an acceptable but not great standard. Assume that in one city there's a group of 20 active mappers who have, in between them, mapped that city, are busy improving it, and where a few of those meet one a month in a pub. Assume that in the other city there are no mappers, and the data is only there because someone from 500 miles away has imported government data. In both cities, some data will be missing, some wrong, some stale. So. Which city would you prefer to be a mapper in - and which city would rather have you despair and give up? And now assume there's a third city of equal size where *nothing* has been mapped at all... maybe I shouldn't speak for everyone but for me (and virtually every mapper I know) surely the city with data-but-no-mappers would be least appealing, far below that with no data.

It might be true for some data but I think its a largely inaccurate statement. There have also been some really well done imports such as the MassGIS one in MA. Not using that data isn't going to get us any further than using it. It makes our data much more useful, so it gets used, which brings in more contributors which Maybe it would be different if there were no open data to import at all, then people would be more motivated to gather it so it would exist. However, if it does exist, weather or not we use it, that motivation is no longer there.

Tough to argue with :) And of course the code is available for anyone to view... although I'm not going to claim that this is really good documentation on the matter: https://github.com/zerebubuth/openstreetmap-license-change Nor can you reasonably expect people to use this as a guideline. And I'm a programmer. There has been talk of the "v0 rule" which I believe is being implemented in the code. This means that the act of creating an object by a decliner doesn't automatically make it dirty. So if a way was created by a decliner with the tag name=Fred and then someone else added the tag highway=footway then after the bot gets done with it, the way will still exist but only have the highway=footway tag. If an accepting user changes the value of the name=* tag then it will be clean... except, see the next paragraph. However if all of the way's nodes are dirty and get removed then the way itself will have to go too since you can't have a zero-node way. I contend, though, that you should not have to change a node to make it clean. If one has tagged a source with an imagery (or GPS) value, they are saying that they vouch for the position of the way, including its nodes. Same applies to removing tiger:reviewed=no (or gnis:reviewed=no). The user is specifically claiming to have reviewed the position and tagging and approved it. Should that not be sufficient? Unfortunately neither badmap nor OSMI fully implement all of these rules so yes there is still far too much uncertainty. But there are some facts to be had. Why, then, is it acceptable for us to be sitting here with a dagger hanging over our heads, uncertain as to when and how it will fall? Shouldn't all of this be nailed down, followed by a reasonable notice period? Why is there a deadline other than "we need to get it done for the long-term benefit of OSM?" -- Alan Mintz ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
