Missing Maps Mapathons as a recruiting instrument about 17 hours ago

@majkaz well locally (that is Switzerland) we do continue to write a welcome message to every new contributor, regardless of what they are using. But I don't kid myself that we are really reaching any of the maps.me or whatever users.

Missing Maps Mapathons as a recruiting instrument about 20 hours ago

@majkaz there is no indication that maps.me or osmand or whatever are a source of any larger mappers at all, and are just as bad, if not worse, than mapathons in that respect. Even though we a churning an order of magnitude more users through such apps than through mapathons.

The above is just a negative if you are trying to sell an app as the saviour of OSM, for the rest it just means we should set our expectations right and not make special concessions because the numbers seem to be so large. And also it doesn't mean that the contributions of such contributors are not useful, just that it doesn't help with expanding and rejuvenating the base of core OSM contributors, the couple of 10'000 people, that do > 90% of all work in OSM. That is our main challenge and what we should be concentrating on.

Local Chapter Congress Notes from SotM 2016 5 days ago

@RobJN the PR implements an opt-out approach (ibecause of that legally likely not tenable, but we haven't looked at that yet in detail) and hiding the permission page itself is trivial, which for example JOSM does.

The other aspect is the reputation risk for the OSMF when a hacker group goes off with the addresses stored by one of the clients, or direct misuse. As I pointed out in the PR it is not as if the OSMF will get the addresses back if they are unhappy with what they are being used for.

Market shares of editors 6 days ago

#changesets is no measure of anything in particular (see numerous other discussions on the topivs), you might as well measure number of key presses per app which actually could be more meaningful.

@HolgerJeromin not sure why you are not looking at the relevant wiki page which includes stats for all identifiable editors.

Market shares of editors 6 days ago

@Kevin well 7 years ago, Merkaator had its peak with 3.5% (not 5%) market share at a point in time when there was very little competition and the numbers in general were very very small (that is why joost sorting by max market share ever doesn't make a lot of sense), it has continued to decline in -absolute- numbers since then even though it had prominent mentions all over the place in that time,

Missing Maps Mapathons as a recruiting instrument 17 days ago

To be fair, all such events, with humanitarian twist or not, are woefully inefficient as a recruitment tool (as in essentially have no effect). I don't know if this was different before 2010 or so, but it clearly has been so for years.

Why on earth did you include Merkaator in the graphs?

OSMF Selling Data to Google? 19 days ago

As the April fools joke obviously has created some real concern, a couple of clarifications:

  • google can use OSM data on the same terms as anybody else and the only thing stopping them are there own strategy product marketing considerations and as anybody else they would just have to abide by the licence. There definitely would be no obligation to compensate anybody for such use. With other words, there is actually no reason that anybody would have to take the trouble to create such a subterfuge.

  • while the presented construct for getting around the contributor terms and the licence is quite elaborate, it doesn't actually work that way. Forks have to continue to be distributed on the licence terms that the forked copy was originally obtained on. The OSMF itself is bound by the CTs to only distribute, or use, the data on terms of the licences approved by the community, that includes making copies/forks, to which the CTs do -not- apply. We have actually discussed if the OSMF even has the freedom to licence Produced Works on any compatible terms, a freedom we afford every other user of OSM data.

Are maproulette challenges undiscussed mechanical edits? about 1 month ago

Have any comments been left on the relevant changesets?

Deteriorating Bing aerial imagery. - Mount Arrowsmith, Vancouver Island, British Columbia, Canada about 2 months ago

Why don't you simply use the mapbox imagery it it is more recent?

While I can understand the moaning a bit,, microsoft did not, and has not entered in to an agreement with "OSM" to provide the latest up-to-data imagery or matter of fact has entered in to any obligation to provide anything. Or put differently: if you are not happy, you should simply go and organize something better.

POI standardization: Tractor Supply Co. 3 months ago

In general POIs are "standardized" via presets which typically provide both the fixed values and fields for those that need to be provided on a case by case base.

Typically you would provide such a preset for both iD and JOSM formats and then lobby the devs to include it.

Maproulette vs SSL vs Privatsphäre 3 months ago

Bezüglich OAuth fundtioniert Maproulette auch nicht anders als alle anderen Tools (JOSM, iD usw).

Dein Login/Passwort wird dabei nicht überhaupt nicht übertragen (das ist ja der ganze Sinn von OAuth) und das einzige was man machen muss ist über eine verschlüsselte Verbindung (nicht wie in deinem 3. Punkt behauptet unverschlüsselt), der sich über ein Token sich identifizierende Applikation die nötigen Zugriffsrechte zu geben. Auch die Applikation (in diesem Fall Maproulette) hat keinen Zugriff auf dein Login/Passwort.

Das ganze ist aber orthogonal zur Frage ob Maproulette jetzt https verwenden sollte oder nicht.

OpenStreetMap Community Statistics Revisited 3 months ago

@joost the "rawer" data would be a rather largish database dump, which I can naturally provide, I'm just not so sure that it would be useful. I can naturally run specific queries if a good case can be made for them.

Given that the published souce code is currently just a readme file the 1kB zips are not that surprising (the source code is totally uninteresting throwaway SQL with some perl around it) :-)..

@Imre that is a bit of an insider joke, those are simply the changsets that couldn't be geocoded because the center wasn't inside a country boundary (see the original blog post), they can simply be ignored.

OpenStreetMap Community Statistics Revisited 3 months ago

To put the "205" in a bit more context, a comparison over the same time period with iD (~78'000 new users using iD over the period from April to December 2016):

                Changes
Editor      >10     >100   >1000
iD          63%     35%      10%
maps.me     11%      1%      0.2%

I don't think this is negative as such, it just shows that users starting off with maps.me are unlikely to be a source of lager mappers that in the end keep OSM alive.

OpenStreetMap Community Statistics Revisited 3 months ago

@BushmanK of the ~89'000 contributors that started off with maps.me ~2'200 tried a different editor at least once. In other words a bit over 2%.

The other interesting number is that just 205 of those 89'000 made more than 1000 changes in 2016. Note "changes" not "changesets", 1000 changes is really small, typically a changeset or two with a conventional editor.

OpenStreetMap Community Statistics Revisited 3 months ago

@pitscheplatsch IMHO the most interesting question currently is if we will see any uptick in longer term mappers due to the large numbers of people starting off with maps.me, or if the underlying trend continues as is

Active contributors per year

3 years of welcome messages, more than 3400 of them 4 months ago

@mmd rarely, however I do superficially check contributions and if necessary follow up with a 2nd message or changeset comment, that will typically get some more feedback.
