Please let me help to understand OLC: is this nothing else than another
representation of lat and lon?
This may be good enough for rural areas and small buildings. But I do
not understand how it should work for very tall buildings.
How would you proceed for those tall buildings?
So how do you provide your OLC? It's the OLC of your actual location?
And you do add the OLC for the entry to your tall building?
(where bells or letter boxes might be located? Or is this an extra OLC?)
And as an extra you do provide the entry to your street?
And this is still a two dimensional address only? How about multilevel
buildings?
I do thing especially about tall buildings with a maze of corridors.
You'd need a list of OLC waypoints how to find your location - within a
building, where GPS will not work.

Hi Martin,
I absolutely agree with you. The OLC is not perfect. All existing
addressing systems remind me the situation with email addresses in early
90s. When moving to another part of a town one had to change the email
address, because it was provided only by an ISP.
But the OLC is open source. It tries to solve the acute problem that
more than four billion people on Earth do not have any address for
numerous reasons: there are no street names, there are no streets,
buildings are constructed "illegally", etc. Even in some cities with
existing inefficient address system finding an address could be a
daunting task. I understand perfectly well that developers in Europe and
North America, where there is a functional legacy system, cannot grasp
the magnitude of the problem. It is something hard to imagine without
being implicated.
It is not only a remote problem. The resulting excessive senseless
driving on global scale in search of a house causes additional CO2
pollution which concerns all.
Since the OLC (plus-code) is open source there will be further efforts
to improve it, to solve the issues which you mentioned and some others.
Using just coordinates, however, is like writing a program in assembler,
it is possible but less convenient than say in C++.
With best regards,
Oleksiy
