[closed] Suspect records found in osm Australia extract.

Hi there all,

while becoming familiar ( and generally playing around with Postgresql + osm data ) with the mapping data system I discovered a set of records, contained within the australia.osm.pbf extract, which might be considered suspect...? I'll let higher authorities pass final judgement, however I include the following SQL style report on what I found.



--         QUERY: ~/Development/sql/suspect_tag_report.sql           --

--        AUTHOR: MjF - 7 Feb 2013                                   --
--   HOST SYSTEM: SuSE Linux 12.1, postgresl 9.1, PostGIS 2.0        --
-- DB EXTENSIONS: hstore, plpsql, postgis, postgis_topology          --
--      OSM DATA: osmosis <== regional data file 'australia.osm.pbf' --
--    OSM SOURCE: GeoFabrik - 1/2/2013                               --

SELECT
  tags->'ref'              AS tag_ref, 
  tags->'name'             AS tag_name,
  tags->'note'             AS tag_note,
  tags->'power'            AS tag_power,
  tags->'source'           AS tag_source,
  tags->'addr:street'      AS tag_addr_street, 
  tags->'addr:suburb'      AS tag_addr_suburb,
  tags->'attribution'      AS tag_attribution,
  tags->'wp:location'      AS tag_wp_location,
  tags->'wp:location_name' AS tag_wp_location_name
FROM 
  public.nodes
WHERE
  tags->'source' = 'Western Power';

-- Above query returns 371 rows with similar output to that which is
-- described below.

-- SAMPLE OUTPUT: single record - fields of concern marked with ''. -- ---------- -- tags->'ref' ==> | 605393 | -- ---------- -- tags->'name' ==> | 605393 | -- ***** -- tags->'note' ==> * This data has been extracted from a -- * Western Power database and should -- * not be uploaded to the OSM database. -- ***** -- tags->'power' ==> | pole | -- ----------------- -- tags->'source' ==> | Western Power | -- ----------------- -- tags->'addr:street' ==> | Absolon St | -- -------------- -- tags->'addr:suburb' ==> | Bumbleyung | -- ***** -- tags->'attribution' ==> * Permission NOT granted for reuse -- ****** -- tags->'wp:location' ==> | 1 E Dawson St | -- ----------------- -- tags->'wp:location_name' ==> | 605393 | -- ---------- -- ---------------------< END OF SAMPLE OUTPUT>----------------------

I wonder if someone could take a look at this as it seems rather suspect on first viewing, comments? Suggestions?

Regards, Michael.

Hmmm...i think things are not that easy at they seem. In Australia's case, the Western Power can be Russia, but this is a Eastern Power. Extrapolating that, America is The Eastern Power in this case but America is a Western Power. So all this raise a question: Why can't we just......get along....^-^

The above example is this node: http://www.openstreetmap.org/browse/node/1959963292 if that helps the DWG at all.

@Kaigara: "Western Power" is probably the name of a power company.

Thank you for reporting this. OSM has the Data Working Group http://wiki.openstreetmap.org/wiki/Data_working_group to deal with such issues.

I've sent them a mail with a pointer to this question. So I think you will get an answer in a couple of days here.
