Tasmap downloads and Backcountry Navigator Pro

I just purchased a map download from Tasmap, assuming I'd be able to load it on to Backcountry Navigator Pro. After going around in circles with no success I emailed for help and got an answer that explained everything: "We cannot process KMZ that is an image overlay. We do not claim to."

So, is there another way to load these maps into this app? I did flirt with Orux a while back at the suggestion of others on the forum, but I found it much less intuitive than Backcountry, so I'd rather not switch.

Backcountry does have inbuilt Tasmania maps (and I've found their maps to be good generally) but thought that I might like the Tasmap for a planned Arthurs traverse.

Thanks.

Can you convert the KMZ to something your app can use? geoTIFF?

Ask Tasmap to resend it in a different format. Or see if there's a way to download it in a different format. Preferably GeoTIFF.

KMZ is not a good spatial data format.


(Note that KMZ is just a zipped KML package. You can rename it to replace ".kmz" with ".zip" and then unzip it and find all the files inside it. You may be able to find the actual image file(s) within it and see if you can do anything useful with them.)

Digital TASMAP files should be geotiff (see here: https://www.tasmap.tas.gov.au/do/category/25000DIG ). Here is a link on how to convert geotiff for use in BCNPro: http://backcountrynavigator.com/using-c ... avigation/

Hope this is of some help. :)

TASMAP also provided a folder with a 48mb TIF file (the map) and a few PDFs (map legend) and txt files. I assume that putting the 48mb file into Backcountry won't work?
I unzipped the KMZ and inside there was a KML file and a folder of smaller TIFs (the map broken into 50 sections).

Looks like MAPC2MAPC is Windows only software. I'm a Mac user.

Thanks Michael. I'll see if Backcountry or anyone on here has a more straightforward solution first. Failing that I might have a go at the geekery! Or I might just use the inbuilt maps...

You may find that you can use the following as a custom basemap

Code: Select all
https://services.thelist.tas.gov.au/arcgis/rest/services/Basemaps/Topographic/MapServer/WMTS/1.0.0/WMTSCapabilities.xml


https://crittermap.zendesk.com/hc/en-us ... ap-Sources


You may then be able to download some of the tiles for the Western Arthurs for use offline

Thanks tastrax. I've loaded the example xml file from the Crittermap link and it works. But I don't see how I can load the Tassie one - I don't understand how this
(https://services.thelist.tas.gov.au/arc ... lities.xml) is a file that I can load. Despite having "xml" at the end it just seems like a web address. When I enter it in my browser I get "This XML file does not appear to have any style information associated with it. The document tree is shown below."

Apologies if I'm missing something really obvious - this stuff is all a mystery to me!

I don't know what format your app needs, but for Mac, you could try to tile your large GeoTIFF file using MapTiler: https://www.maptiler.com/ . It has many options for tiled output formats. I used to recommend it for users of my old iOS mapping apps (and had a deal with the author of MAPC2MAPC to produce tiles native to my app too).

The message you are getting in your browser is the correct behaviour for un-styled xml. So don't worry about it.

I've had a read of the linked crtittermap page and I think you need to right click on the link and save the WMTSCapabilities.xml file. As detailed on the crittermap site:
This can be placed in the bcnav/custom file on your storage for use. If you download this file in your mobile browser, it is often a mystery where the file goes. The answer is that files are usually placed in the <storage>/Download folder.

Once you have a copy of the xml file in the bcnav/custom folder you should be able to open it from within the BCNPro app.

Hopefully I have got this right. :D

Michael.

Thanks Michael. I did this and "Tasmania LIST Topo Maps" now appears as an option for a Map Source in Backcountry Nav. But if I select it then no map comes up. Something ain't quite right!

Thanks Son of a Beach. I'll keep that in mind if the other approach fails. Or I might just be happy with the inbuilt maps, which seem decent. Of course I'll take paper maps too. :D

The map tiles should be viewable whilst you have a 3g/4g connection on your device. It might take a while to initially load and generally the tiles (where you look/zoom around on the map) will most likely cache on your device for a period of time.
