I've only had the traveller app for a week or so and used it on a trip on the weekend. My main use for it is off road exploring and I found that the national park 4wd tracks that I could see on a 1:10K topo from the gov website was not visible on the ETOPO. I have the XHIRES OFFLINE license and maps are installed. Am I doing something wrong or is the data just not in ETOPO2021?

Thanks

Dave,

Have you zoomed right in? Max zoom gives you 1:2k. If you have and the track is not there then the data is not in EOTopo 2021. There is a map update coming, though I don't know the timeframe.

No single map set or navigator app does everything for everybody, unfortunately. However I find a combination of Traveller and Ozi Explorer running on an Android tablet with a squillion maps to come close.

Thanks. Nothing shows at Zoom Level 18 so I guess its not in the data. Attached some screenies of what I mean.

qld topo 1:10k

ETOPO2021 with trek showing small spur onto 4wd track but the track is not visibile in ETOPO2021 even at 18 Zoom.

I've seen similar for newer NSW National Parks. You can also look at the satellite images to see if the tracks marked on the NP map exist. For new parks the tracks in EOTopo can be the former station tracks that have been closed or re-routed. In unfamiliar remote areas where I want to ensure that I know where I am in relation to actual tracks on the ground, I have created a private trek based on waypoints created using the satellite image and cycling/walking/straight line navigation.
