Great Central Road.

The co-ords you have given are decimal degrees,
You prob want degrees minutes and seconds.

Go to a site like www.fcc.gov/fcc-bin/convertDMS and convert them there.

eg the conversion for the co-ord you mentioned is

25° 3' 57.6756" Latitude

128° 9' 35.9100" Longitude

Good luck.

Gidday...I think you were lucky not to have had trouble with youyr tyres...pressure needs to be up considerable to protect the tyre from damage when on rough, gravel stong ground etc....always a compromise between ride comfort and tyre protection..and I know someone will disagree with me.........thats their choice.but I am talking personaly from many many thousands of Km travel on bloody awful ground...and most people I have come across with tyre problems on that country have been running on lower presuure

The issue of co ordinates is simple.....Your GPS can display in easting and northings that is UTM's or in Lat . long.....Nothing to due with WGS 84 that is a map datum....The settings in your GPS can be altered to display either co ordinate system that you choose. Most will display a primary and a secondary on one of the nav screens so as you can read both if you are travelling in one but trying to find a reference in another

Thanks for the report graimejohn, we are headed out that way in a few weeks.

Cheers

If your using a Garmin don't add those little ° dots like that because it won't work

and this is your Co-Oedination in hddd.mm'ss's

Agree with outback2 entirely as to keeping tyre pressures up on the rough stony stuff.Also depends on the type of tyre but on my split rims Iwill have a minimum of 45lbs when loaded on the rough stuff and never had any serious tyre problems.Seen plenty of low pressure "fatties" destroyed by running too low pressures.Again only my opinion from years of experience.

Strange your GPS doesn"'t have decimal degree display for coords - most do. Finding the setting that displays the coordinates in the format you want will be easier than entering data into spreadsheets/calculators¡Kand then re-entering them into GPS (it would even be easier if you used OziExplorerƒº.

What GPS make and model do you have? If you disclose this infoI am sure someone her will be able to clarify if it is possible or not and make your life easier. Typically options to change display coordinates are in the setup section of the menu under coordinates systems or some similar title.

If you in fact don"'t have a GPS that is capable of showing decimal degrees, apart from method already described the conversion process is simple maths.

In the example you show the first whole number is the degrees (i.e. 128).

To get whole minutes just multiply decimal section of the number by 60 (i.e. 0.159975 x 60 = 9.5985). The first whole number is minutes (i.e. 9).

To get whole seconds multiply decimal section of the minute result by 60 (i.e. 0.5985 x 60 = 35.910).

This number represents seconds which you can round up to 36 if you have to. So 128.159975¢X = 128¢X 09' 35.910"

Thanks for all the replies.Gps is a Magellan explorist xl with discov aust tracks and had a model gp15 for over 10 years.Both very easy to use but tried all settings and cant find one with that amount of numbers.Aus 84 was close but not the same.Showed all the guys where i work who have a gps and none of them could figure those numbers out.Wgs 84 on my unit has 3 settings and i usually use degrees minutes and seconds.Tried 80 kph but 100 was smoother going once up to speed.Guy that owns tyre shop has same 2005 model turbo hilux with a heavier tray,mine is a roscos ali canopy set up for fishing and camping and he runs the same tyres at 32 psi.Will see what head office says, but he has seen it happen before and recons the compound is to hard.For anyone going soon some good spots to camp are empress spring a bit off the road where David Carnegie nearly came to grief but camp back down the road about half a kay and docker river was nice with sunsets over the ranges fireplaces and flushing toilots to keep the laidies happy.Collect wood before you get to docker river.Very cold at night with minus 4 one night and zero the norm.Lots of camels with over 800 shot at Warakuna in a week because they were pulling air cons off the walls to get at water.Saw two cats in the middle miles from any water,thought dingos might kill them tru survivors those things.Back on tyres.Most of our fishing is on the south coast and at one spot have to deflate to 10 psi and have never had a problem rolling a tyre or puntures if you go steady.Also the central road was far better than expected.

No Wiillem it was empty, bit of a let down if that had happened to Carnegie.
Must have been hard going walking through that country to Halls creek and back.We also camped at Niagra Dam and that was a nice spot as well,plenty of wood next to the old rail line on the way in.
