Scaling multilingual name tags with Wikidata 4 months ago

The tiny weeny issue with this is naturally that there is the underlying assumption that wikidata is correct and that the data meets our quality criteria (as in actually being in use and not invented).

Updated Contributor Statistics 5 months ago

To use your analogy from your last paragraph, our main "income" is the time and work our contributors donate. So yes, how much is contributed in that sense is clearly an important KPI and not something that should be glossed over. If we only had contributors using maps.me to edit, well then we wouldn't actually have a map.

I don't believe anybody is claiming that the edit count is a perfect metric, but it is clearly a lot better than counting changesets which was never particularly good and has now become completely useless. Separating out POI edits would be rather difficult and would require detailed analysis of every edit, and naturally agreement on what a POI actually is.

I haven't seen or heard of anybody taking the position that a maps.me user can't be part of the OSM community, but I would expect such a user to want to be part of OSM and not simply be declared as such for marketing reasons. In turn that requires actually knowing what OSM is and the lack of that is what has been widely criticized.

The edits corresponds to the num_changes attribute in the changeset dump, which is roughly the number of objects deleted/modified/created. Creating a 4 node building from scratch should end up with a count of 5.

But that doesn't really matter, because even if you were to "normalize" the maps.me number by multiplying by 5 (given the popularity of doodling buildings) the total contribution share would still remain under 1%/month.

As to the edit numbers levelling out (which likely they are not, I suspect in reality it is simply not so rapid growth, all a question of how you scale the diagram :-)): in lots of places where OSM is really good we are clearly seeing saturation effects in that the low hanging fruit has been mapped and adding meta data of all kinds tends to be a slow process.

With 60-70'000'000 objects touched in one way or the other each month I don't really believe that even stagnation would be an issue (one day we will have something near complete coverage of all major features and then undoubtedly the number will start falling, would that be a problem?). .

Tagged and Untagged Nodes 5 months ago

The redaction process created a large number of orphan untagged nodes, typical example of that happening would be when a road was redacted away, but the nodes not (because they where created / moved by somebody that accepted the CTs). As a result the nodes may still have residual geometry information (by how they are arranged) and should only be removed when that aspect has been checked.

The other source of such nodes are naturally (broken) imports, unluckily there is no penalty for not cleaning up after you have messed up.

Using OSM to improve government data 6 months ago

Nodes in Asian cities in the last 10 years 6 months ago

2011 is simple to explain: its the first year we had a good global imagery resource in the form of Bing. While we previously had access to the yahoo product, coverage and quality was rather limited.

Vespucci 0.9.8 Release 6 months ago

See https://github.com/MarcusWolschon/osmeditor4android/issues/232 The main problem is that I need to design, add and test UI elements for multiple dozens of possible OH elements and variants of them.

Let's Talk Local at the Global State of the Map 6 months ago

I nearly fully agree with Glassman: local chapters happen when there is a local community and maybe semi-formal local groups that have come to the conclusion that a formal organisation makes sense and could be sustainable.

There is no indication that doing things the other way around does anything for community development and I would oppose any attempts and any tendencies to require or even just to imply that higher degrees of formal organisation are necessary to participate in OSM. Besides driving away contributors that are specifically not looking for that in OSM, it just makes it too easy to install a Systemé Blatter.

A look into a sample of edits from MAPS.ME contributors from August 6 months ago

WRT the new contributors per month stats: it isn't so simple, given that there was both the launch of the maps.me editing capability and a larger HOT/MM event during the same period.

Down the road once things have stabilized a bit there will be some analysis, given that the peaks alone doesn't really say much.

@planemad well it is not different in that respect than numbers that MB published claiming everything is fine and dandy ......

"Welcome-to-new-mappers" program in the Netherlands comes to an end. 8 months ago

Marc I think it is a bit of a shame that you are stopping with sending the messages (as you know I've been running something similar since late 2014 for a similar number of new mappers per year in Switzerland).

While I'm the first one to agree that there is not much feedback or noticeable behavioural change, it does give the 10% or whatever that map a bit more a fighting chance of finding national/regional/local resources that otherwise would be very difficult to find (I have over the last two years put some effort in to improving the relevant parts of the general signup process, but as it is currently, it is difficult to provide region specific messages).

Off to message the six new mappers from today....

What's going in Egypt? 8 months ago

PS: naturally it could simply be that there is new imagery available, but the user in question would seem to be a very very prolific mapper in that case.

What's going in Egypt? 8 months ago

It is not unlikely that that is Facebook see http://forum.openstreetmap.org/viewtopic.php?id=55220 if data is breaking it would be important to give both facebook and the DWG (data@somfoundation.org) a heads up.

Experimental publishing of Sentinel 2 satellite data 8 months ago

@imagico iD has been using the "best" imagery for an area as default since early this year, and has been recommending it in the layer selection since it exists AFAIK.

Arme OSMF 9 months ago

@russdeffner of the good $1'000'000 HOT expenses last year roughly $750'000 was used for salaries and related things, not really different than any other organisation, commercial or not.

What is at best misleading is claiming that the projects are "OSM community building", they are simply things which of interest to HOT (which is naturally HOTs good right), but are neither coordinated with the wider OSM community, nor of interest too it.

Just as the techincal projects, with the one exception of the tasking manager which has seen some use outside of a narrow HOT focus, were neither speced with a wider OSM audience in mind nor are of general use. Some are obviously direct HOT marketing activies, for example "OSM analytics" which uses exessive lean-to doodling as a quality metric, which is really only useful for missing maps marketing.

Updated contributor stats 12 months ago

@PlaneMad except that in depth (numerical) analysis doesn't really show a clear seasonal pattern. Yes, sure, end of year tends to be slower, but thats about the only thing that can be said, it clearly doesn't explain the specific large drop (which btw your highlighting shows nicely).

CR+ID Crowd-mapping Workshop using OpenStreetMap - Prosperidad & Tandag, Caraga, Philippines about 1 year ago

See http://vespucci.io/tutorials/presets/ various bits and peices are just relevant for yet unreleased 0.9.8, but 0.9.7 should be able to digest all of it.

CR+ID Crowd-mapping Workshop using OpenStreetMap - Prosperidad & Tandag, Caraga, Philippines about 1 year ago

I wouldn't know what is fiddly in tag-only editing mode (you need to switch out of it to add new features but that is just a long click away). One of the major advantages of vespucci is that you can use customized presets which can make adding stuff real fast, and naturally, because you have the actual OSM data available, you know what is really already present in the data.

Currently vespucci can't read .osc files (not that that would be a big thing to implement, simply nobody has turned up with a reasonable use case), it supports writing them and reading and writing JOSM format OSM XML files.

As already said OsmAnd is fine, it just doesn't seem to make a lot of sense to use it if you are specifically going out surveying.

CR+ID Crowd-mapping Workshop using OpenStreetMap - Prosperidad & Tandag, Caraga, Philippines about 1 year ago

Any specific reason you used OsmAnd and not Vespucci for data collections? OsmAnds festures in that respect are at best rudimentary (ok for on the fly non-dedicated POI adding),

Any specific editing you are concerned about?
