For now I will change it to none in the description and template files, as that value seems to have more traction than no.

Agreed on supporting one value and avoiding confusion. I followed the wiki recommendation which is at second glance arguably unclear. Under no it says * no is preferred, despite this tag being in wide use. So what does that mean? Is *no preferred, or none?

Zverik - not yet but it is at the top of our list for the next development cycle. This may be a couple of months away, though. Sorry.

Mike - I can help out with proper file conversion if you want. I realize PBF format can be tricky as an input file format. On the other hand it does help raise the barrier - this tool should be used with caution. Using PBF as input file format forces the user to think about the data in an OSM context.

Let me know how I can help.

k1wi - Not fixed yet. I’ll see what I can do. We’re all on holiday break now so it will be 2016 for sure though.

anewuser1: I’ll look into HTTPS download. As a workaround, you can use the web site for now..

MikeN, Clifford - I will be looking forward to looking at your data together to see if Cygnus can help.

Hi Jorge - no it’s not open source (yet..). I am working to get to a point where we can do that. The engine relies on an internal, proprietary SDK. For now (to also answer Mikel’s question) I plan to do a series of more in depth articles that explain in more detail what happens behind the scenes.

If you have a specific use case you would want help with, I would be happy to discuss it!

It would be interesting to see what the value of mapping really is. A marketplace like you suggest might make that visible if it gets enough traction. Do it!

Rob - that is a very valid question. You are correct, MapRoulette encourages remote / armchair mapping, which is why we need to be very careful about what good and appropriate MapRoulette challenges are. I believe very strongly in MapRoulette as a tool to encourage remote participation. In fact, it was when I first moved to the U.S. and saw the vast amount of work that needed to be done to clean up and update imported TIGER data, that I first got the idea for MapRoulette.

In this particular example, we can rely on the TIGER (US Census basemap) overlay to retrieve the names:

But you are right, wherever we cannot fall back on reference data like TIGER in the US, a ‘missing names’ challenge would be a really bad MapRoulette challenge. So thanks for pointing that out.

Making MapRoulette into a field tool that can be used on mobile devices is high on my wish list. I would be very excited to get some help in that area :)

Welcome Andy! Let me know if you have any questions. I am curious to hear what you think about the data quality in the Dallas metro. What are you specifically interested in mapping?

======================================================== Comments above this line were from when there was a placeholder here…

Great initiative! We should talk on Skype soon. I would absolutely love to help.

andrewpmk – acknowledged. those are hard to filter out purely based on trips, because like you said, the majority of folks will be driving in one direction. Is there distinctive tagging that we could use to give those cases lower importance?

gileri - Thanks for adding the link to the wiki and adding the manual to the wiki :)

J-Louis - In Scout, we definitely take into account the historic speed profiles. Actually, they are more important in navigation than the actual maxspeed tags, because they tell us how much time it actually takes on average to traverse a segment of road, rather than theoretically based on speed limits. Because this information changes continually and is not independently verifiable, it is not suitable for adding to OSM.

25or6to4 - thanks for reporting the cluster dot issue, we will look into it for sure, that is annoying. The green quickly copies the lon,lat to the clipboard, we thought it may be useful to paste the coordinates in some other application. We may remove it if it’s not useful or confusing.

TheDutchMan13 - I dig your avatar :D

updated the post to include a reference!

thanks for reminding us of Autopista, a great tool if you ask me.

literan – I only found one case in Moscow: http://improve-osm.org/trafficFlowDirection/#17/55.76057/37.62802 - should this be marked as an invalid case?

Hi everyone - thanks a lot for trying out the tool and sharing your experiences. We will be working on improvements to reduce the false positive cases and your responses will be very helpful in doing that. Here’s what I see so far:

Very short segments

There seem to be more false positives among these. We will look into filtering these out or otherwise dealing with them.

Using OSM GPS tracks

We will be looking into that. I will check in with Grant to see if we can get a fresh dump of GPS traces. (The most recent one is from 2013.)

Changes over time

Local traffic rules / patterns may change over time, we can see if we can detect changes in traffic flow. We currently do not do that yet.

Roundabout and other less common oneway tagging

Roundabouts are implicitly oneway, we will look into filtering these. Also look at oneway=reversible.

Other improvements

• Marking tiles as invalid / solved in web interface - we’re working on that already (also for Missing Roads.)
• Change ‘Edit in ID’ to ‘Edit using OSM.org preferred editor’.

Please try and send a location with any problem you find, so we can reproduce it. That makes it much easier to act on any reported issue. Thanks!

Simon – the positional accuracy of the marker is tricky, I quickly found that out also. My first tests that I describe I actually did on foot, but the positional uncertainty would increase with speed. So my thinking is that in a driving context, you would need to focus on ‘big’ features such as lane configuration and turn restrictions at intersections. That is what I hope to test soon.

Richard – agreed, transcribing voice notes is very 2006. Thanks for the Vespucci reminder. I had not used it for a while because I don’t have an Android phone, but it looks like it has come a long way.

SK53, and Richard – Validating with simple (yes/no?) responses to questions is something I see for a ‘Mobile Maproulette’. I would love it if someone built that :)
