Joe<br><br>nice work!<br><br>I've only had a quick look around a few SI areas that I'm familiar with on map compare and the imported data would be huge bonus to the map<br><br>there are some obvious omissions and variations as you mentioned one that stands out to me is the omission of the Rakaia River which is more than a small creek! <br>
<br>and also Canterbury some roads shown as minor tracks but as I see it having them is a huge bonus as they can be retagged later to correctly display etc from local survey/knowledge<br><br>I don't have you tech skills but would be happy to assist with improving correcting the data after the import as I have quite alot of local knowledge and about and about all over the SI<br>
<br>thanks again for your good work<br><br>dave (gerkin) <br><br><br><br><div class="gmail_quote">2009/7/1 Joe Richards <span dir="ltr"><<a href="mailto:joefish75@yahoo.com">joefish75@yahoo.com</a>></span><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

I've been working on the LINZ data import, on attribution/legal as well<br>
as the actual import. The LINZ data I have is actually via the NZ<br>
Open GPS project and is in Polish Map (.mp) format, which seems<br>
to use Garmin types for its features.<br>
<br>
I've hacked around with a few other scripts and have created a python<br>
script which creates .osm files, and then imported them into a local<br>
postGIS instance I run at home. From there I've generated tiles using<br>
Mapnik and uploaded them to a dev server for your perusal....<br>
<br>
Upload is still in progress but most are there already (starting in the<br>
north and working south). It's just south of Christchurch already and<br>
I have gone and rendered Dunedin, Queenstown and Glenorchy ahead<br>
of time. If you find zoom 16 is not visible then zoom out a bit until you<br>
find the available tiles. As mentioned all of the north island is done.<br>

<br>
Notes:<br>
* import was done on a basic world map (from vmap0) to provide<br>
coastlines where they were missing<br>
* some large rivers have a lot of detail, but some seem to be missing<br>
altogether (e.g. Lower Hutt river) - this was also missing in the NZOGPS dataset,<br>
not sure why<br>
* tiles are still being generated and uploaded now (Tue 30th June),<br>
but all of the north island to 16 zoom levels is done as well as the<br>
Tasman... South of Christchurch is still being uploaded (although some<br>
tiles are there at lower zoom levels)<br>
* I think most of the road types (primary, secondary, trunk) etc<br>
might be completely off, including the link roads. Please send me any<br>
specific instances or comments on this<br>
* No attempt made to support anything like turn restrictions or<br>
relations since this was missing from the original dataset<br>
* Roundabouts seem to have an issue as well, where their parts are<br>
missing<br>
* large lakes such as Lake Wakatipu near Queenstown were split across<br>
two datasets, and as such as not showing up<br>
* central cities seem to have more detail in the existing OSM data<br>
(except perhaps some missing street names) but rural areas have<br>
less... This is ok, but your thoughts are welcome on how to merge<br>
these<br>
* parcel boundaries (cadastral) information, showing property boundaries,<br>
shapes, and house numbers will be imported separately, ie are to-do<br>
* Department of Conservation parks, national parks, reserves etc are<br>
also to-do, although some are present in the current dataset.<br>
* No data is merged with current OSM data, so this is really to spot problems<br>
before we attempt merging. It has been suggested we might use<br>
the java-based RoadMatcher for this. Your comments are welcome.<br>
* Thanks to Geofabrik.de for allowing me to use their "compare" javascript<br>
<br>
I will also put up the .osm files generated by the script so you can<br>
check out whether the data is there, but just incorrectly tagged.<br>
<br>
Please feedback to me anything you see, especially if it is incorrect.<br>
Since the plan is to merge this with the existing Openstreetmap data,<br>
missing features that are in OSM are less of an issue than features<br>
that should be in the imported dataset but are not (and hence are<br>
missing on both).<br>
