Whats in the pipeline for the next Vespucci release? 7 months ago

@santamariense you don't have to change anything see http://vespucci.io/help/en/Presets/ (note that vespucci uses a different (better) translation system).

OSM braucht ein neues openstreetbugs 8 months ago

Ich kann mich nur MarkusHD anschliessen irgendwie hast du die letzten 2 Jahre verpasst, OSM Notes erlaubt essentiell alles was du forderst und es gibt auch genügen Apps die die API unterstützen. D.h. nicht das es an der Notes API nichts zu verbessern gäbe, aber das ist eher im Detail als grundsätzlich.

Du kannst auch falls du das Gefühl hast gewisse Tags fehlen oft einen entsprechenden TEst für OSMOSE vorschlagen (aber vermutlich gibts den eh schon).

Updated contributor stats 8 months ago

@EdLoach there has at least been hint at some seasonality in the past. I had a look at the per country new contributor stats and they really show that there was a bit of shortfall across the board with the exception of Germany, the US being something over 300 new contributors lower than average.

OpenStreetMap active users 8 months ago

Paul did you remove zero-edit changesets? Up to at least March 2011 they are quite significant distorting factor see http://www.openstreetmap.org/user/SimonPoole/diary/23352.

How to draw the buildings in ID editor 8 months ago

Not to mention that per object source tags are in general not needed and worse tend to be nonsensical in the long run.

What comes first, Map or Database? Should we tell newbies the truth? 8 months ago

@BushmanK ehhh I was actually agreeing with you, pls go back and re-read my comment. The only thing I was pointing out is that the discussion is not in any way new. For example the reoccuring theme of if we should actually show a map on openstreetmap.org at all, or if something more like openstreetmap.de would be better.

10.000 broken Turn_Restriction in the OSM Planet File 8 months ago

Funneling the information in to maproulette would probably make more sense (or in to osmose)

What comes first, Map or Database? Should we tell newbies the truth? 8 months ago

You've touched on a subject that is rather controversial and I've pointed out many times that there is no point on jumping on newbies, sometimes not even "new", screaming it's a database when we don't actually say that upfront or even anywhere hidden. The text on the wiki you are referring to goes back to at least http://wiki.openstreetmap.org/w/index.php?title=About_OpenStreetMap&oldid=1461 so this has been a problem that has been with the project since the beginning.

We have a similar "we a can't tell newbies the truth" situation with relations (which are in reality a simple concept).

Improving the OSM map - why don't we? [12] 8 months ago

Actually ... the concept of attaching a source tag (except in extraordinary) circumstances to an object has been defunct since the introductions of changesets,, 5 years or so ago and it has been not considered good practice for multiple years.

Portable OSM 8 months ago

I wasn't suggesting that JOSM would fit your needs, just that the basic principle is not new, and that there is a large body of experience with the issues. Matter of fact every non-broken OSM editor has to handle the problems with syncing edits to the central API and dealing with conflicts to some extent. Naturally there is some value in being able to stage edits in some fashion to avoid network problems and similar, none of the current editors really deals gracefully with that, but that is a long long way from requiring a full OSM stack replacement.

Portable OSM 8 months ago

The main issue I see is that this is being developed in its own sub-culture without any interaction with major parts of the OSM dev community. More specific OSM has had distributed editing and syncing with the central API for ages, for example with JOSM (not to mention any other editor that support offline storage and conflict resolution ie Vespucci).

However anybody who has edited over longer periods with JOSM without syncing knows that the end result can be very very messy, and the project as outlined has the potential to produce conflicts in abundance. It is unclear how the AMR is proposing to avoid this. No go Zones? Zap any non-AMR edits? ????

Non-searchable = Non-existent 8 months ago

google used to return individual OSM objects quite prominently, they seem to have stopped doing that. Can't blame them, they -are- a competitor and why should they give us preferential treatment.

There has been some work on providing OSM data in a more search engine friendly way (well actually in a more search result friendly way) however that hasn't been completed yet and in any case it is completly unclear if that would help with the competitive issue.

Place Names: Old and New 9 months ago

Typically old names would be tagged as old_name (:-)), now that doesn't help except if somebody produces a map that displays both but that isn't really a major undertaking.

Missing Dam in Germany 9 months ago

The actual body of water has been mapped since 7 years. I suspect we didn't even have a tagging for the dam itself at that point in time.

When we refer to Germany as being complete this refers mainly to the road network and the larger cities, outside of those areas there are still lots of details to be mapped, not to mention things like house numbers (we should be crossing the 50% mark in Germany very very soon).

How large are our national contributor communities and how are they developing? 9 months ago

@Dacor I'm not quite sure where google is supposed to enter the picture. Even if the newbie in question doesn't get a welcome mail from the community (which a lot do), it is just a question of clicking on the help tab above to get links to everything relevant.. And further the welcome page every mapper sees contains a link to the same place https://www.openstreetmap.org/welcome

Using IRC (the web interface does not require any software to be installed), the mailing list and the forums does not entail creating a further account and while not super user friendly isn't quite as unfriendly as you imply.

Naturally more things could be done, and I think we are all waiting with baited breath for somebody to finish off the groups functionality for the website which would make some community things substantially easier.

How large are our national contributor communities and how are they developing? 9 months ago

@51114u9 South, I'm aware that this is controversial, but probably less than including it in NA. See the caveats.

How large are our national contributor communities and how are they developing? 9 months ago

@RobJN I'm on the record as saying this before: it is reasonably easy to cause spikes in our growth by media coverage (we know that because it is easy to track cause and effect in such cases), changing the long term trends seems to be very difficult. There are just are handful, or even less, events that have affected that, the introduction of Potlatch, the licence change, iD. I could speculate on why that is, but the truth is that we don't actually know what keeps our growth going (my take on it is that it is actually word of mouth but thats unproven).

The good thing to take away from the country numbers is that they show that even in the countries we consider developed in an OSM sense growth rates have flaten out but growth is continuing, in other words there is no reason to believe that you can't reach > 1 mapper per 1000 in the UK too.

How large are our national contributor communities and how are they developing? 9 months ago

@imagico theoretically yes, however living as I do in a country that is a reasonably popular tourist destination there has been no indication that this is a significant effect over the last two years (where we have looked at every single new mapper).

The other problem is that this effect would only be detectable at all if the mapper in question actually continued to map at home over a significant period of time, which as we know most don't. (there were only 33'197 contributors with more than 100 changesets as of this September).

Mapping my hometown Rajahmundry 10 months ago

@Jothirnadh (welcome to OSM) lots of us have been through the misaligned imagery valley of grief :-) Which includes major parts of Europe just a couple of years back.

The main problem seems to be that there is no reference information right now to adjust the imagery.

There are essentially not so many ways to generate/get such information:

  • make precision measurements with a GPS device of well defined features that have good visibility on the imagery (for example a corner of a 1 to 2 storey building on which you can access the roof)

  • generate (multiple) GPS tracks over crossings and turn offs (you will need multiple tracks on both sides of the road to get resonable information)

  • get official reference point information from the governement or similar (typically this is not so helpful because the points themselves tend not to be visible on imagery)

Advancing Columbus 10 months ago

@union4 Naturally if it is just a misunderstanding and you don't intend to import but want to trace the outlines, sorry. However you should understand that we have suffered and continue to suffer from hit and run imports in the US that as a tendency tend to be badly executed on top of that.
