Please can someone send me the GPS reference for the campsite on the Great Central Road that is now the only allowable camping site between Yulara and Giles. I am sure I recorded it when we researched the trip but I can't find it!!! To spark your memories, is a bush camp with an honesty box at $5 per person run by the Ngaanyatjarra Land Council.

It is located 7km east of the WA border, which puts it about 1km from the Docker River settlement. Come on, someone look up your gps files. David is betting me that I'll get my answer in less than an hour... who's it going to be?

Michelle if you do not get a reply here, I would suggest you ask on this list:

There are some serious travellers there, and a great opportunity for you to push ExplorOz in a subtle way. Never miss an opportunity.

Cooridnates without a specified Datum - ouch!

Personally, I don't use DD MM SS any more and the majority of land lubbers now use UTM Universal Transverse Mercator. It really is the superior system and meaningful. Even the US search and rescue organisations are going metric and switching over to UTM. The MGRS they dreamt up is a nightmare. UTM is meaningful and is in standard metric metres that everybody understands.
This is just one:

Ozie, correct me if I am wrong but when using Lat long the Datum is irrelevent , Lat long is the datum ????This is why i still use lat/long no datum confusion!

Sorry Brian,
I hit the wrong button and accidentally deleted your qn about what I meant by " enter odd " it was a typo, a word was missing, it was meant to say entering the odd one (meaning coordinate).

Brian try entering Latitude and Longitude under different coordinate system and see what you get.

Ozie I tried what you said ond you are right! But why???
I use ONC maps to get co-ords for my GPS( old manual input) but no where does it state what datum to use on the map! DO you have any answers???? I rearly use utm co-ordinates (all that RAAF training in long lat) I have a log book of all places I have been in long lat (WGS i think )but are they accurate , you have turned my world upsidedown!

Brian because different Datums bend and twist the earth in different ways.

All maps intended for navigation should always specify the Datum

If your log book is in WGS84 and your GPS is set in WGS84 which would be normal practice, your coordinates would be correct.

If you are using moving map software the only time you change your GPS Datum is if you are using UTM, and then you use the Datum on the map.

Thanks but since I'm using it for trek notes, where our standard is WGS84 and Lat/Lon I'll stick with that.

The lat/lon coordinates are for those users that want to enter the odd into their gps manually, or compare with their current position or to look it up on a grid reference on a paper map. Since the Hema maps still display the lat/lon grids I think its probably appropriate to stick with lat/lon in this instance.

the reason Hema are using Lat/Longs is the because of the scale of their maps - 1:1 250 000, 1:2 000 000, 1:500 000. Apart from remote area travel, most people would be using 1:250 000 or 1:100 000 scale maps and at this scale Lat/Longs are very difficult to plot - notwithstanding those lucky enough to have the maps loaded or using a laptop. Data can be entered using either then switch your settings to whatever suits.
Foe an explanation of terms Datum. Lat/Long, Grids etc have a look at - http://www.auslig.gov.au/geodesy/datums/#Whatisadatum

A quick look at my Hema 1 : 2 000 000 shows your reference must be veeeery close to a turn off to Kulail, just east of Docker River. If that's the place you're talking about it's close enough for me........

Haven't been that way for many years but with your co-ordinates I reckon I'd find it.... :)
