Simple Australia topo map viewer

The link below is to a free program that displays online topo maps for Queensland, NSW, Victoria, South Australia, and Tasmania, as well as a world wide topo map.
The maps are the Queensland Qtopo maps, NSW SIX maps, Victorian Mapshare maps, Location SA maps, Tasmanian TasMap maps, and Open Topo Maps world wide maps.
Download the file to a local disk drive, and double-click it. It will open in a browser. It is written in Html and Javascript, and the source code can viewed (and altered) in a text or Html editor, such as Notepad.
It has been tested on a Windows 10 computer with Google Chrome browser, but may work in other modern browsers. It is written for a 1366x768 pixel screen size.
It can load and display a gps gpx file, and allows tracks and waypoints to be drawn, and saved as a file, which can be downloaded to a gps.
The user is responsible for ensuring that use of the maps is allowed under copyright rules. Copy-Paste the web addresses to read the terms and Conditions for each map.

I've added another version that allows a gps sensor (or location services) in a device to be used to show the current location. Javascript support for a gps sensor is very basic, so it is not reliable.
If the file doesnt open properly in Android, it may be because Android is not using the Chrome browser to open it. Try opening it with the Chrome browser by typing file:///sdcard into the Chrome address bar. This will show the folders in the Android Internal Storage. Tap Downloads, and then the file (assuming you have downloaded it). It should open and work in Android.
I also fixed the Magnify and Wpt display bugs. Testing is so tedious!

You might be better off using the following for Tasmania as it has various scale tasmaps as you zoom in and out

Code: Select all

It's great that you've written the code from scratch. If you're looking to learn stuff, that's fantastic. If you're just after the end results, you'd get a lot more speed and in-built functionality with a purpose built library like Leaflet.

I've used that for my NSW mapping tool (https://maps.ozultimate.com/)

I've also knocked up a similar tool for TAS
https://maps.ozultimate.com/archive/tas/
I think they do the same things as you're looking to implement (load GPX files, create tracks/waypoints, save to file etc), but also include things like scroll button to zoom, click to drag, drag-and-drop GPX files etc.

My code is licensed under MIT Licence, so anyone is welcome to pick it up and use it somewhere else. It's pretty easy to add a new source - eg another state, if the tile service(s) are available.

Thanks Ken, I've had a bit of a play with the Vicco mapping. Seemed to work well, thanks for going to the effort.
Cheers GG

There's a new version 1-3 of the online topo map viewer in the link below. Changes include: Drag map to move it (or use the arrows), better NSW and Tas maps, save gpx or text files of drawn tracks and waypoints directly to local disk, plus bug fixes.
The mobile version 2-3 is not draggable. Tap the map to move it. See the post on 16 Oct above on how to use it.

Thanks for the link Tom B. In the planning stages of a round walk back from Jenolan to Katoomba after completing the SFT.
Good to be able to see both the Jenolan and Katoomba sheets on one screen as opposed to the Six Maps views.
