PM me if interested so we can divvy up the downloads so they don't overlap. I've requested the first 5 today.


Can someone point me at the appropriate download site. I think I can help with this too.
Is the data covered under CC4?

I read some T&C's https://maps.six.nsw.gov.au/etopo.html that look prohibitive. But maybe I am misunderstanding them or have the wrong website.

Possibly, but the T&Cs are a catch-all for the SIX Maps site, which covers a lot of different services/data. We can consult with SS as to whether this data can be used for the relevant purpose.

I must admit that I hadn't read the t&c very carefully. Most other states use CC4. I think it would breach the following:
2 Access to Products
2.1 Unless otherwise agreed in writing by Spatial Services, you are prohibited from:
a. on-selling, or on-supplying, or sub-licensing products in any form to any other person or entity; or
d. rebroadcasting, reformatting, making available online or reconstructing products or part thereof; or
e. otherwise publishing, blending or dealing with the products.

2.2 Unless otherwise agreed in writing by Spatial Services, you may not do any of the following with the products:

a. alter, blend or combine the products or part thereof;


I'll try and follow up with SS about it.

If you download they should be in shapefile format. I'm not sure if I can deal with the data volume - it is likely to add up to 50Gb.

They have in the past been willing to agree in writing to other uses for the data, so certainly worth asking.

It's in Mapinfo .tab format, but I can convert to Shapefile via QGIS.

Based on what I've seen so far, the whole dataset is probably about 1.5Gb compressed for NSW (includes roads, parks, spot heights, point of interest etc). But the contours, hydroareas and hydrolines probably make up at least half of that.

Thanks to a few people, I have a copy of the NSW clip and ship data. Total size is around 1.6GB (Mapinfo .tab format)

Out of interest, I extracted and merged all of the watercourses in QGIS, and exported them as a shapefile. Compressed it came to 500MB. Uncompressed it is much more - about 3GB. But that's mainly duplicate tags and empty space in the DBF file that gets compressed to nothing. Most of the tags are probably redundant for the purpose of making maps.

I assume that the contours and waterbodies are probably another GB or so.

Makes quite a pretty picture in QGIS too!

I contacted Six maps via the website feedback last week, but have not had a reply. Does anyone know a better way of contacting them?

There's a variety of contact details on https://www.spatial.nsw.gov.au/contact_us - I'm a bit surprised they haven't responded, but if you used the web form, it might be worth sending an email.

OK. I have a reply now. All good. All the data I want to use is under a CC licence so can be used in my Garmin maps.

I spoke to my contact and he was very helpful. On 22 Feb they are releasing a new range of products from the Spatial Collaboration Portal. It's partly available already - Google "nsw spatial collaboration portal" to have a look. There will be 2m contours from LIDAR. Obviously too detailed for Garmin maps. They could be filtered back to 10m, but the download would be seriously large I suspect.

What is the best way for me to get your data? Before you go converting all the mapinfo data to shape files I'll check to see if my program will read mapinfo.

Cheers

My script reads mapinfo files just as easily as shape files, so is it possible for me to download the data?

By the way, I don't need all the data merged. Separate zip files for each LGA is fine.

New versions of all OSM maps based on OSM data as at 05/02/2020. New version of VICMAP based on latest track data from VicMap.

New NSW map
Finally NSW now has all contours, cliffs and hydro from Spatial Services data. NSWSIX is redundant and has been removed.
Thanks to Tom Brennan for supplying the topo data.

Cheers

Unfortunately I don't pay a lot of attention to the SA map. When I looked I noticed that the wide, dry river beds were rendered solid blue. Yes it is laughable. I've just uploaded a new version that renders them as brown dots.

Also for SA, I noticed that the contours data that I used only covers the 1:50k map area. No contours are shown outside this area.


Just in case there was any misinterpretation. I wasn't laughing at the quality of the cartography. Rather, I was humoured by what nature does: once in every couple of decades or so, many watercourses could be in flood. The solid blue would be most apt. Murky reddish-brown with log jams even better. So now I've got a choice of SA maps to use, depending on the weather!


Andrew, thanks as always for the most recent updates to the series. Intriguingly, the SA map this time combines solid blue and (the much more realistic) brown dots. Possibly in random fashion, unless you're just trying to see if we are paying attention to the maps you don't have any compelling reason to "pay a lot of attention to"!

Many thanks, I really appreciate having such regularly updated maps.

I noticed a few people asking how to use these maps on a macbook, so I thought I'd share what I do.

https://imgur.com/a/RelzGyw

Instructions below:

https://i.imgur.com/NqqRnVR.png

Create a folder using whatever name you like, place a folder called "GARMIN" in the root of that folder. Put your map files inside the GARMIN folder. I've used "OSM Feb 2020" in this instance.

https://i.imgur.com/cDdX4aM.png

Start Disk Utility, click "File>New Image>Image from Folder".

https://i.imgur.com/K5N61tk.png

Choose the folder you created in step 1.

https://i.imgur.com/Xj8IzaS.png

Create the image, you can turn on compression to save some space, though it won't be a big saving if you do (I saved about 10%).

https://i.imgur.com/INcHDZO.png

Once the image has been created browse to the new image in Finder (this will be in the same place as the folder you created in step 1). Open it with Disk Image Mounter.

https://i.imgur.com/rWTpn2y.png

You can now launch BaseCamp and use the maps as though they come from a Garmin device, you may need to wait a little while at first launch. It will be super fast by comparison & not require you to have anything plugged in when you plan your adventures.

the quality of the new NSW map is great. my garmin is loving it :-D
thank you very much for the effort to put it all together.
cheers.

Thanks peregrinator. Glad someone is awake. It looks like the error was introduced between 14-24 Dec. Looking at my notes I can't see what has caused it. It will need a bit more investigation.

Fantastic work Andrew! Loaded happily on both Garmin eTrex 20 and OruxMaps on Android.

Hi all,

NEW
Maps for New Zealand. Hydro, contours, forest, scrub, scree and shingle data from LINZ. All other data from OSM.

NSW
The previous version has issues due to me merging files with duplicate IDs. You may not have noticed any problems, but I advise you to update to this version. I believe it is quicker to load.

SA

Fixed (I think).
Also added the more basic SRTM contours for the area outside the 1:50k map range.

ALL
Updated with OSM data as at 14 Feb. Changed some of the rendering and zoom levels. Forest and scrub now shown. Would welcome feedback on the colours and if it makes the other map detail difficult to read.

Cheers
