Re: [HOT] Open Location Code

[john whelan]

Except we don't hold the z coordinate in the OSM database.

There are other addressing schemes such as three words but using the lat
and long for the address is much simpler.  Encoding it with OLC gives you
the advantage of a more human friendly looking address.

There are issues which have been discussed in OSM-talk about adding tags to
the database.

In a conventional house number street address you can expect that number 4
main street will be between 2 and 6.  Unfortunately if you have no street
names and no house numbers it gets more difficult to confirm you have the
correct address using anything but a lat / long based scheme.

Re: [HOT] Open Location Code

[Victor Sunday]

Yes,every point on the surface of the earth is  already coded with x,y and
z coordinates ,which to the lay man is imaginary lines of latitudes,
longitudes and altitude.With the emerging  and advanced smart
technology,its application maybe  represented  and accessible in various
formats but the principles remains the same.

I guess,we are on thesame page ?

Re: [HOT] Open Location Code

[Warin]

+ 1 with John Whelan

Every place already has an "address" simply called latitude, longitude.
The Open Location Code is simply another way of expressing that 
latitude, longitude.


If some platform wants to provide an interface between OSM data to Open 
Location Code fine.
But I don't expect that the OSM data base will have anything other than 
latitude, longitude inside it.

Trying out OLC in some local circumstances, driven from on the ground

Re: [HOT] Open Location Code

I think you have missed a major point.  You do not give anyone an OLC.  It
is simply their lat and long encoded in letters.

So every building in the world has a lat and long, it is its location.
This can be expressed as an OLC.

Trying out OLC in some local circumstances, driven from on the ground
up in that location is fine. If they see a possible usefulness to

[HOT] Open Location Code

[john whelan]

 Open Location Code or Plus code is just a method of representing latitude
and longitude in a more human friendly way.
It was originally created by Google but has been released under an open
licence.

It is possible to set osmand to show coordinates as OLC.  This means it can
display the OLC code for any node or building in OpenStreetMap and the
displayed code can be copied to the clipboard.  No extra tagging is
necessary.

OSMand will also accept an OLC code for searching purposes.

It would seem likely that Nominatim will allow searching by OLC in the near
future.

Translation is this allows us to give every dwelling in Africa etc its own
address.  It is not in itself a complete addressing solution since it
doesn't handle things like 2nd floor but it does at least take you to the
building.

To make this work will require training material for example how to turn it
on in OSMand.  It is not turned on by default.

Because it is calculated from the buildings's latitude and longitude it is
embedded in OSM and will not disappear.  It is stable so you can build on
it.

Now you need to think about how it can be used and what additional
resources will be required to make full use of it.

Re: [HOT] Ebola Outbreak Nord-Kivu Building Geometry analysis

[Ralph Aytoun]

Hi Pierre,

One of the problems we face is that some very inexperienced mappers have been 
inadvertently marking task squares as validated and, while we are able to see 
in the Tasking Manager 3 how many squares that person has validated there is no 
mechanism in the Tasking Manager to identify those specific validated squares. 
This problem is being addressed at the moment with some urgency but, as with 
the Project 4947 that you used in your building analysis, although all the 
squares are validated some have not actually been checked properly and 
corrected. 

Once the means is there to identify all the task squares in a project that have 
been validated by an individual we will be able to reduce the percentage of bad 
buildings even further.

I am glad to see that you are developing the means for us to identify the work 
done by an individual mapper as this will make it easier for validators to 
assess the standard of that mapper’s work overall and thus give them the 
appropriate helping hand and encouragement to improve their standard and become 
our more experienced mappers of the future.

If you are tired on the Talk list discussion about the gender of post codes, 
What's about OSM data quality ;)
Building Data quality Evaluation after Tasks are completed and validated is 
possible by the analysis of the Geometry of buildings.
For 3 jobs completed for the Ebola Response, you will find below links to 
Achavi. This will let you evaluate rapidly if this seems to satisfy OSM data 
quality standards.  Even if the Task manager indicates jobs as 100% validated, 
this seems to confirm that validators are demotivated and do not want to 
correct anymore imprecise building tracing from successive waves of one day 
contributors.
