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.

<p>Hi Martin,</p>
<p>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.</p>
<p>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.<br>
</p>
<p>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.</p>
<p>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++. <br>
