[Talk-lv] LVM roads import final step

[Vladislav Kugelevich]

Hi
I started importing, and it goes fine. I'm at cell 5 from around sixty. If
you want to help, please join telegram  group

>From my experience, validating and cleaning of an imported cell takes
around one hour, depending on its density. Sometimes it is just 15-20
minutes, sometimes two hours.
Please note: *issues are inevitable with imports! *It is just a matter of
compromise between occurrences or map corruption and benefits of a new data
being imported. IMO, import still overweights some cases of corruption
missed during validation.

*About excluded roads. *All roads that are part of relation or have names
same as roads in relation are excluded. Otherwise, it is too easy to
corrupt relations.
Another thing that is not ideal is that we can't correct the geometries of
the existing roads with the current approach. This is related to how
Hootenanny works and is hard to overcome.
We have a reference map (OSM) and a merged map (LVM). Reference map is
considered "better" and if something exists there, it is not modified. In
our case, geometry exists, but tags sometimes do not. We can't switch the
reference map to LVM, because it would cause another set of issues. Again,
I am not an expert by any means, so this is just my understanding.
