|Let's Talk Local at the Global State of the Map||5 days ago||
Thanks Glassman, you're right about terminology. I'm using Local Chapter here loosely (too loosely it seems) .. but I really see it as a spectrum, and don't think that formalizing is the first step, far from it. Do like Harry's thinking about building an on ramp.
|A look into a sample of edits from MAPS.ME contributors from August||8 days ago||
Thanks @joost schouppe. Exactly -- there's a rational and smart way to go about looking at maps.me, based in real assessment and cool heads and respect for each other and all mappers.
I do wonder looking at these issues, how could maps.me adapt to address some of the issues discovered.
On the stats, I would be very surprised if the scale of this jump meant was due to something other than maps.me, since HOT and Missing Maps events occur frequently. One way to dig into this would be to look at each newly signed up users and look at their changeset comments.
|Welcome to the new Missing Maps||7 months ago||
hey @woodpeck --- I'm reading your comment and having trouble understanding exactly what you think is an issue here. OSM purposely doesn't spend much on publicity, or develops software -- but makes an API available for anyone to sign up to and use, as long as the community norms of mapping are followed. Missing Maps as a project has not been in an OSM vacuum, and this is far from the first site to share statistics on how we're mapping. If tangible issues develop, there's plenty of room to address -- OSM never stopped from doing something out of fear of what might go wrong, otherwise we'd never have started! In any case, the code for this is open, and I think there's huge potential to apply analysis at scale on OSM for all sorts of purposes -- how else can we make OSM better through infrastructure such as this?
|Data and community in the Belgian regions||7 months ago||
Oh of course --- was using Mazermind tools as well for analysis with OSM Epic https://github.com/Project-EPIC/epic-osm Turned out, very difficult to manage the scale of data in OSM History, in a database.
A recent break through for me, via working at Mapbox on this stuff, was using OSMQATiles and TileReduce processing. http://osmlab.github.io/osm-qa-tiles/. This is what drove the country cover work (links at https://www.mapbox.com/blog/how-complete-is-openstreetmap/).
For example, was able to very quickly write and run script to count and visualize users by join date in OSM. I mean really fast --- writing the processor took less than an hour, and running takes less than a minute.
OSMQATiles covers what's in OSM right now, not history, and doesn't include relations. But even with these limitations, can derive enough actionable information to get a good picture of the community. I wonder, can we think of what questions where current OSMQATiles is sufficient, and whether the simplicity of the approach and speed gives a lot. And what critical things are we missing, and should we looking into a full history QA tile set as well.

Great research @joost%20schouppe. What tools are you using to run these stats? Would love to see this kind of local community research available everywhere, on an ongoing basis.
Pretty interesting how this is amplified when only analysing nodes. Raises the importance of something we don't capture in metrics easily --- what kinds of features edited on user and location basis.
If we had contribution stats by feature types at various admin_levels, would be able to identify particular community data strengths and weaknesses. The highway coverage analysis was one step in this direction https://www.mapbox.com/data-platform/country/#belgium.
Another important element to capture is recency --- you might have great coverage, but if it all happened 5 years ago, the community is not very vibrant.
This is pretty interesting. A lot of mappers cross borders, and identifying who is local and who is remote is tricky. Would love to have a service which provided
1) per user, a list of the number of edits per admin boundary, along with the most likely "home" 2) a list of users per admin boundary (also at multiple levels)
|Picturing Proposed Development at Josephite Seminary in DC||9 months ago||
@dieterdreist yes, this is more for conversation. I certainly hope the eventual project is more sophisticated, and that it seriously takes into account other ideas put together by the community.
|A new version of the OSM Edit Report is here!||10 months ago||
Thanks for the suggestions @imagico. Both of these improvements have been discussed, and are both complicated for different reasons. Looking forward to share more, when the knotty problems get sorted out.
|Conflation engine Cygnus now in public beta||10 months ago||
Very curious to read more about the process and code Cygnus applies behind the scenes, and how it can be extended to other kinds of features.
|The most inefficient way in North America||10 months ago||
@bdiscoe nice work. would love to see a TileReduce version of this, to make it easy for anyone to run repeatedly in any country
|The history and completeness of OSM||10 months ago||
My understanding is that the methodology is based on random sampling and visual inspection, not on assumptions of distribution of roads. We should be able to investigate more once the code is opened. I agree, 90% sounds a bit high overall, but it is an estimate after all (not something true or false). Many of the numbers align but not completely with https://www.mapbox.com/blog/how-complete-is-openstreetmap/ (where the completeness numbers are comparison against CIA World Factbook), so will be an interesting comparison The trajectory graphs are helpful in a lot of cases to spot some dynamics in communities.
|HOT Voting Member Nomination||11 months ago||
Love the focus on validation ... there are connections to HOT's documentation, activation protocol, and technical developments.
|Missing Maps Workshop at Mapbox-BLR||11 months ago||
Great wisdom Maning!
Some things we put together over the last year on organizing an event, from MapGive http://mapgive.state.gov/box/en/process/event-planning/
|OSM-PH tagging suggestion||11 months ago||
Just seeing this now @maning and it is awesome. I don't think I've seen anything like this before, except in my mind after too much mapping! Super useful perspective, illustrates the process of observation and data creation in the real world.
|How we apply map feedback||over 1 year ago||
There should be and are many levels to contribute to OSM, so this is a good concept, and thanks for the transparency. To pull out a productive idea, offering a path to users giving feedback (and notes), to get more involved in OSM, is a useful idea.
|HOT 2014 Review||over 1 year ago||
Thanks for your sharing this Sam. I encourage you to open your ears a bit more to what's happening in HOT community and organizationally the last six months. You're already doing this a bit, since you answered the call to document HOT activities in 2014. I see things as substantially improved. Eager to hear more ideas on how we all can be more constructive, together.
|Vision?||almost 2 years ago||
Non-editable requests from HOT? You must be confused. Reference please.
|Moabi at State of the Map US||about 2 years ago||
@butrus_butrus: Some data might be appropriate for sharing in OSM, or even being based in OSM. No specific plans at the moment, but something we are continually looking at.
|Moabi at State of the Map US||over 2 years ago||
Yes, definitely maning. We're gearing up for that, will let you know.
|You can't do this with any other map but OpenStreetMap||over 2 years ago||
Thanks @lxbarth. I like the idea of highlighting what you can only do with OpenStreetMap, we should collect these. Here's a few more: http://brainoff.com/weblog/2012/02/02/1756
|Is the OpenStreetMap Rails App Appropriate for Other Data Sets?||over 2 years ago||
@nfgusedautoparts: they may work. but since our use is outside of osm.org properly, we have more latitude in implementing new features.
