Thread: So many questions.

I don't anticipate getting lost, but it is handy to know where one is in case of emergency

With respect to GPS accuracy I think that the GPS receiver will have better accuracy than the map details used to show you where you are. This is particularly the case with maps of outback areas where maps are not highly developed and the databases to overlay the roads and waterways contain rough low renolution data.

I think if you took the coordinates from the GPS receivers you would find that they would be well within 100 m and more likely down to 10 m, coordinate system and reference points all being equal.

I beg to differ. If theses items are sold in Oz why "should they be" on an American format? GDA, Geocentric Datum of Australia would be a far better system and any decent GPS will give a option!

Sam, would it be unreasonable to expect an average speed of 80kph?

Because many maps are in WGS84...

And the difference ~100mtrs

Sound familiar

Let me add to that:
WGS84 and GDA94 are the same (Hema use these)

These replaced older AGD66 and AGD84 which reference out by ~200mt

Fire away...

I would say an average of 80kph is more than achievable. I did a relaxing drive from Boulia to Tobermoray which took about 4 hours. I took it easy that day and had my camp set up by mid day at Tobermoray Station.

The following day I did Tobermoray to The Gemtree without doing any hard driving either.

The NT side of the Plenty/Donohue is rougher than the Queensland side at the moment but it's certainly nothing that'll slow you down by any great amount. There are a few very short rough patches that you have to slow down for but nothing that'll really hold you up.

I hope this helps!
