[Talk-it] R: R: Terremoto in Emilia Romagna

[Sky One]

Ciao,

dopo l'import dei dati di Concordia sul Secchia, sono stato contattato
da un utente (pnorman) che mi ha chiesto lumi circa il mio operato (mi
verrebbe da dire "cazziato", ma è stato molto gentile :-) ). Vi
riporto il suo messaggio e la mia risposta, con preghiera di
correggermi se ho detto castronerie e/o di contattarlo pure se credete
che la mia risposta sia stata lacunosa o errata.

I noticed you importing in Italy in the changeset
http://www.openstreetmap.org/browse/changeset/11762408

I looked for documentation for this import, but couldn't find any.
Could you please point me at the wiki documentation and the discussion
on the imports mailing list that happened before this import? As a
remind, the import guidelines are at
http://wiki.openstreetmap.org/wiki/Import/Guidelines

They also call for imports to be done from a dedicated account.
Providing links in the profile of that account to the import
documentation can be helpful

It also looks you deleted all the existing buildings, for example
http://www.openstreetmap.org/browse/way/78321342 and
http://www.openstreetmap.org/browse/way/152081061

The second one had tags on it.

Why did you delete these? It looks like you deleted existing data to
import data, which is not recommended.

You can find the page about importing/mapping data from Regione Emilia
Romagna here: http://wiki.openstreetmap.org/wiki/Emilia_Romagna/Terremoto_Emilia_2012

There are the Talk-it's threads about what to do after the earthquake
and how to import data:

I made the import how it's described in the "Inserimento con JOSM"
paragraph of the
http://wiki.openstreetmap.org/wiki/Emilia_Romagna/Terremoto_Emilia_2012
page. I do a resume for you:
1) open the OSM file derived from the Regione Emilia Romagna's DB
2) open the same area
3) check (manually!) what buildings are in the OSM DB now and
are/aren't in the Regione Emilia Romagna's datas and delete the double
ones: this is made 'cause the buildings in the Regione Emilia
Romagna's DB are better than the previously
4) check with the "PCN 2006" WMS that the building are georeferenced correctly
5) upload data to OSM

As I said, the new datas are better than the older. As you can see
it's not an "automatic" import, but there's always a human check ...

Please let me know if I'm doing something wrong, because as italian
community we are planning to import more buildings in the same way. Of
course you can write to the Talk-it mailing list (don't worry about
the language - you can write in English).
