All unsealed roads in New Zealand

Thanks to @jonibarteam for kicking off this project and @ray_taylor, @frotz, @simon_Kerr and @Isaac_Bain for jumping in and adding their expertise.

Huge thanks to @eric_yu for picking this up and getting it working on a new service after Google discontinued the Fusion Tables service the original map was hosted on.

The map below shows all ‘metal’ roads in NZ over 5km long.

By default the map only shows metal roads longer than 5km. To see all metal roads in New Zealand click “Map & Tool” then the “Layers and Legend” option in the upper-right corner and enable the “nz_metal_roads_all” layer.

If the map is too slow loading on this page, you can access the map directly here.

This map is based off data provided by Land Information New Zealand (LINZ), changes to a roads status since the LINZ data was last updated e.g roads being sealed or temporarily or permanently closed will not be reflected in the map below.

@jonibarteam has been working on a project to put together a map of every unsealed road in New Zealand.

When he has a file ready we’ll overlay it on a map of NZ for all to see.

Check out our page devoted to this project, and map of every gravel road in NZ over 5km in length.

What sort of info is needed? How can we contribute?

WAMPS has public access roads and paper roads mapped out, which I use a bit.
And I have also got a few kml files from LINZ for various purposes – not sure if they have sealed / unsealed status in their records or if that is up to all the local councils to keep track of.

Hi Guys,
Here you have the first piece.
This is a map with all the unsealed roads in the North Island.

This is RAW data from LINZ and does not provide information if the road is public or not… that is the next step.

Blue Roads are unmetalled (Dirt) roads.
Red Roads are metalled (Gravel) roads.
Link for to download North Island Unsealed roads

If you click one road a info box pops up with the surface and name of the road.

Some (most) I would guess are private or only provide farm or property access but they are easy to spot, general they look short in the map.

Ways to contribute:
Anyone that knows how to code in Python.
A list of public roads would be nice so that we could exclude the ones that are private.

Adding some of this info to openstreetmaps would also be very useful as it would provide information to GPS apps.

Next steps:

Add the South Island Map.
Add the Tracks map (the ones vehicles can go on)
Remove Private roads from the map.

Enjoy, are happy riding.

PS: Edward funny enough the “Joni” in Jonibarteam is a guy. 😀

Haha, Fixed

Assumptions make an ASS out of U and ME

I was going to set up a page with the file overlaid on a google map, and overlaid on a topo map, but the file is too big to render on the page.

Hi all, nearly back from epic riding overseas. i downloaded the link (from here in Singapore airport), but what file opens it? Thanks to all who are working on this. It will be a massive tool for the riding community 🙂 🙂

KML can be opened by Garmin Mapsource or Basecamp, or GoogleEarth, not Google maps though.

I had a look at some of the Wellington metalled roads. Good luck with getting access to a bunch of them. That said, there are a few there that I’m completely oblivious to, so a good excuse to see if i can ride them…

Hi,
Yes the problem with LINZ data is that is does not have info regarding the access type of the roads (public or private), I had a conversation with them and they said that they don’t have that info…
I was redirected to WAMPS but the info is also not usable, and the site it self is sooooo sloowwww.

So it has to be a team effort… and all are excuses to to go and check 😀

Cheers

Whats the difference between blue and red lines?

All of the blue lines I have looked at in the waikato/Coromandel were private driveways rather than roads.

I couldn’t get it to load in Mapsource but Goolge Earth worked, though it’s slow.

After a bit of messing around I managed to get it on both Google Earth and Basecamp … all good. It certainly makes finding gravel a whole lot easier. Thanks!!

Cool. I’m a Python programmer. What kind of coding did you have in mind? Does WAMPS provide accessibility info? Merging that seems really useful, if possible.

Hi frotz
Yes Wamps does have some information, however I see no API.
A good thing would be to try and link this data with Openstreet maps.

Send me your e-mail via PM, and we can start having some chats about it.

Cheers

The roads that the LINZ data service gives you should be all public roads – some will be paper roads which are still public roads and the public can access them.
