Re: [OSM-talk] Mapping Klong Toey Slums

[Oleksiy Muzalyev]

Power poles, wires, wind, trees are usual dangers for multirotor 
aircraft too. There is also an issue of a large bird attack. These risks 
could be mitigated via sport flying.


I usually train sport flying at a stadium very early in the morning when 
there no people there. I have got a small trainer quadcopter, several 
foldable Air Gates, and Air Flags. There are also gates at an American 
football field with high poles, which are good for learning to fly in 
narrow spaces.


I have an impression that birds being excellent fliers themselves can 
immediately see the level of piloting skills of a RPAS (Remotely Piloted 
Aircraft System) pilot. If they see that it is an friendly experienced 
pilot they usually do not attack. In any case I regularly train diving 
and other BFM  .


In addition to aerial images I also film aerial video. Video provides an 
additional information. For example, recently I filmed a medieval 
Bilhorod-Dnistrovskyi fortress [1] in Ukraine. I upload a video to 
Wikimedia, add a video link to the Wikidata page, and add wikidata tag 
to the OSM map for this object.


Wikimedia accepts videos only in open OGG and WEBM formats. 
Unfortunately, some quality is always lost during conversion to these 
formats. You can see the same HD video at youtube and compare the 
quality [2]; I tried all convertors which I could find for Mac.

[Rob Nickerson]

In case you're not subscribed to our newsletter or the osm blog:

Thanks to the support of our amazing sponsors

we have kept the Early Bird tickets for State of the Map available for as
long as possible. With less than 8 weeks to go until we gather in Brussels
the Early Bird offer will soon come to an end.

You have *until 7th August* to grab your price savvy tickets

now before normal prices kick in.

Don’t forget your accommodation though! The number of rooms available in our
hotel deal

drops by half when Early Bird closes so book your room before it’s too late.

Re: [OSM-talk] Uber most likely using OSM data

[Frank Villaro-Dixon]

The best thing would be to use the Uber API to receive the route instead, 
so we could compare the lat/lon of the points with the ones stored in db.  
But it seems that this API returns an image instead:

https://developer.uber.com/docs/rides/api/v1-requests-map

So we could instead use the "estimates-price" api:
https://developer.uber.com/docs/rides/api/v1-estimates-price
which returns a distance. This distance should match the OSM distance.  
Could this be right ?



Cheers

Re: [OSM-talk] Uber most likely using OSM data

[Tim Waters]

Hello,

given they may well have a very large body of GPS traces, they may be
using these to route along.

The way to check if they are using OSM is if the OSM map has
intentional errors - a kink in the road where there is none on aerial
imagery or on our GPS traces, for example.  Some of my early edits
were done just by phone and a bluetooth GPS mouse - in the days before
aerial imagery, and some of the roads had a few bends which were not
there in reality, and this assisted me in identifying some of the
previous users of our database.

Another way is perhaps by comparing the resolution of the data, a bit
like in the examples, showing where the bends meet up - comparing a
road with lots of bends, nodes in a short distance. Seeing if the
vertices match up.

Cheers,

Tim.

Re: [OSM-talk] Go Map!: Mobile mapping on iOS

GoMap!! is limited in its capabilities to edit relations to reduce the chance 
of breaking anything. Without being sure, when splitting a way that is member 
of a relation, both parts continue with same membership. This might give 
undesired results in very few relations, so I think it is a safe approach for 
an app that doesn’t do editing of said relations.

relation membership is shown when you select a member and go to "tags", you
can select the relation, see the members and roles, and modify tags. You
can't (AFAIK) create relations, and from a quick test it seems splitting
ways of a turn restriction will result in inconsistent relations (two from
members in this test), i.e. if you split a way it will likely keep all
(new) members in the relation regardless of relation type (i.e. routes and
multipolygons will not break when splitting some of their members).

I'm sure complex geometric operations will likely destroy relations (e.g.
splitting a member, deleting one of the resulting ways, redraw it and don't
check or care for the relation), but for simpler usecases (draw short piece
of missing way, add nodes, move stuff, add or change tags) it is "the
almost perfect mobile editor".

When I first heard of GoMap, it was along with some criticism that it didn't
