[Talk-ca] Land Information New Zealand (LINZ) & NZOGPS to Openstreetmap import

[Joe Richards]

I've uploaded most of the tiles (starting in the north and working
south) generated from the import script I've been working on which
takes Graeme's NZOGPS (Polish Map format) files and turns them
into .OSM files and from there I've been rendering Mapnik tiles.  They
are visible here

Notes:
 * import was done on a basic world map (from vmap0) to provide
coastlines where they were missing
 * some large rivers have a lot of detail, but some seem to be missing
altogether (e.g. Lower Hutt river) - this was in the NZOGPS dataset,
not sure why
 * tiles are still being generated and uploaded now (Tue 30th June),
but all of the north island to 16 zoom levels is done as well as the
Tasman... South of Christchurch is still being uploaded (although some
tiles are there at lower zoom levels)
 * I think most of the road types (primary, secondary, trunk) etc
might be completely off, including the link roads.  Please send me any
specific instances or comments on this
 * No attempt made to support anything like turn restrictions or
relations since this was missing from the original dataset
 * Roundabouts seem to have an issue as well, where their parts are
missing
 * large lakes such as Lake Wakatipu near Queenstown were split across
two datasets, and as such as not showing up
 * central cities seem to have more detail in the existing OSM data
(except perhaps some missing street names) but rural areas have
less... This is ok, but your thoughts are welcome on how to merge
these

I will also put up the .osm files generated by the script so you can
check out whether the data is there, but just incorrectly tagged.

Please feedback anything you see, especially if it is incorrect.
Since the plan is to merge this with the existing Openstreetmap data,
missing features that are in OSM are less of an issue than features
that should be in the imported dataset but are not (and hence are
missing on both).
