Thank you Hamish for the information!.
Now I've completed osm_dataset_overview and status is 6.5final in status
sheet.

Javi Sánchez.

I've been trying to update osm_dataset_overview. I have
noticed that feature_city data and PostGIS Databases must be
included. I've already done it, but without description[1].
I wonder if any of you can help to add short descriptions to
them, just is case, this is already done in any other
document.
Hi,
I was responsible for creating all of those extracts, let me
know if you get stuck.
On the other hand, I wonder if there may be other cases of
OSM data included in any other kind of databases, like
spatiallite, Rasdaman....
hopefully not, and we're all working from the same base dataset.
[1]
- Nottingham.osm.bz2:
A large extract of the greater city area as a BZip2
compressed XML text file.
- Nottingham_CBD.osm.bz2:
A smaller subset covering just the central business
district.
Right, the smaller CBD version was created for pgRouting to
keep performance high.
Nottingham was chosen as it will be the host of FOSS4G 2013
in September. Minneapolis (home of FOSS4g-NA 2013) is a much
bigger city & so much bigger dataset, but for this release I'm
thinking to maybe have the "View OSM online" menu entry point
to MN instead of Nottingham. (thoughts?)
I'd note that I haven't run a new Xapi/Overpass extract for
the data since Aug. 2012, but at this late stage in the release
cycle I'm a bit hesitant to touch it.
(see http://download.osgeo.org/livedvd/data/osm/Nottingham/)
- feature_city.osm.bz2
- feature_city_CBD.osm.bz2
These are simply stable symlinks to the host city files. All
quickstarts and overviews should use these file/path names so
that they don't go stale and need to be updated every release.
- feature_city_poi.db
this is a sqlite DB of "positions of interest" nodes extracted
from the above feature_city.osm.bz2. Contains pubs, fuel
stations, restaurants, etc. Technically the osm2poidb program
which creates it comes from OSM's code svn, but is currently
built as part of the GpsDrive package (which is a bit of an OSM
hybrid project with source code partially over at OSM's svn).
OSM data imported into PostGIS Databases:
- osm_local
- osm_local_smerc
imported with osm2pgsql, they are the full feature_city.osm
datasets, one imported to lat/lon (epgs:4326), the other into
the infamous "Google spherical mercator" pseudo-projection for
generating Mapnik webtiles. Perhaps with some osm.xml magic
Mapnik could be trained to just use the osm_local db, but I
haven't tested that.
hope it helps,
Hamish
