NSW Map data

[mys]

Hi,

I've put together simple web page to show LPI Topo Maps (and other maps): https://dl.dropboxusercontent.com/u/292 ... topo2.html

It contains the following layers:
- LPI_Imagery_Best
- LPIMap
- LPITopoMap
- LPITopoMap_S1 (Old series topo)
- sydney1943 (b&w aerial imagery around Sydney and Blue Mountains)
- various Google Map layers
- OSM Hike & Bike
- markers from www.immortaloutdoors.com and wildwalks.com
- and SCA $44k 'no entry' zones

The idea is to show one of the aerial base layers (via top right button) and then semi transparent topo overlay. It is possible to select multiple overlays but result is not that great (apart from "No entry", Immortal Outdoors, and wildwalks because they are just paths and markers)

Enjoy!

Nice, cool to see the Special Area zone overlays. I've been working on mapping the Metropolitan and Woronora special areas in OSM based on real on the ground boundaries. Unfortunately the arbitrary lines on a map don't quite match up with the signage on the ground! Useful to have this overlay reference though, the official maps/overlay are a bit lacking in detail usefulness.

Wow! I like your work.

am liking the hike and bike overlay

Great work pulling together all the different data layers that are out there on the web, thanks for sharing.

That's very cool. Thanks for putting it together!

I see that the Lake Woodford "No Entry Area" includes half of Woodford village, and the Lake Medlow "No Entry Area" includes almost the whole of Medlow Bath. What gives?

Yeah. Indeed, it is strange. Boundaries are taken from Water NSW website: http://www.waternsw.com.au/water-qualit ... cted-areas

So no driving through Medlow Bath along the Great Western Highway. As Wilf Hilder used to say, "It's grand country. Forty-four grand!".

this is really good mate.
I have contacted the author of gpsMapEdit asking him if it is possible to include those maps in his app. I had no idea there was an API for available.

Public roads and private land within the boundaries of the Special Areas is excluded.

Also certain specific areas, such as
- Walls Cave (Blackheath)
- the Mt Cookem section of the Katoomba to Mittagong walk
- Narrow Neck (for bikes, given it is only a restricted entry area)

An interesting question would be - what is a public road?

Do old paper roads count? What about fire trails?

[Grabeach]

In a Special Area the only public roads are those that the SCA allows the public to use. What's shown on a map, historical usage, location, construction, even affect on water quality, is largely irrelevant.

Do old paper roads count? What about fire trails?

In NSW it is controlled by the Roads Act 1993. This Act defines a "public road", somewhat unhelpfully, as:

"(a) any road that is opened or dedicated as a public road, whether under this or any other Act or law, and
(b) any road that is declared to be a public road for the purposes of this Act."

The Act contains provisions on how roads can be opened or dedicated. One way it can happen is for a registered plan of subdivision to state the intention of land to be a public road - this is commonly known as a "paper road". In these circumstances a paper road is a pubic road.

Any member of the public has a right of passage by foot along a public road (s. 5 of the Act). I'm no expert in this but I suspect there are other provisions of the Act and accompanying Regulation that restrict that right of access in certain circumstances (for example, adjacent to an expressway).

Hi mys,

Awesome work pulling all the may layers together - it's super handy! I love that you have the old NSW topo series layer (LPITopoMap_S1). I used to view the layer on the old version of SIX Maps (a few years back) and was disappointed when it wasn't included in the updated version. I was wondering where you sourced this layer from? I can't find it on the LPI Web Services site, only the current topo series.

Thanks!

I was enjoying using and learning from this map but now i cant get the link to open. When i click it downloads to my computer and i am unable to open file. Any suggestions or tips would be appreciated

New Dropbox limitation. From Dropbox website:
"Dropbox Basic (free) users: Beginning October 3, 2016, you can no longer use shared links to render HTML content in a web browser. If you created a website that directly displays HTML content from your Dropbox, it will no longer render in the browser. The HTML content itself will still remain in your Dropbox and can be shared.

I have a related tool at http://maps.ozultimate.com which you can play with in the meantime

The old web services are still there at http://maps.six.nsw.gov.au/arcgis/rest/ ... s/sixmaps/

However LPI has made some changes that make them difficult to access. For example, the tiles for the old Series 1 maps can be retrieved - but only if your browser does not pass an HTTP referrer address!

It's possible to work around this by using HTTPS (which doesn't send an HTTP referrer address). This is why that layer worked on mys's Dropbox version up until the other changes. I have knocked up a version of my mapping tool which has the old and current topo map layers. No guarantee how long it will continue to work as LPI can probably change these servers at any time.

https://maps.ozultimate.com/archive/02a_opacity_s1_s2/

Note that while this can be accessed through HTTP (instead of HTTPS), for the reason given above, it will only give you the current layer, and not Series 1.

I've put most of these into a MapProxy config that caches the tiles locally and can be used to clip and merge layers (for example using an authentication handler which uses a Shapefile to merge NSW/QLD maps along the border).
