I hope someone here can help with this?
I am after a navigable file for the Aust Alps Walking Track that I can load onto my GPS.
We are walking this track in Oct/Nov this year and would like an extra resource mainly for track confirmation. We have all maps, GPS and the Siseman/ Chapman guide book.
Any help appreciated.
Rick

wilray wrote:Hi, very interested in gps files for the aawt, when i checked out the Karen Cody link though and tried to type in the coordinates they didnt seem to work on my Garmin E trex 30. for eg. Cleve Cole Hut - Mt Willis the gps co-ord's were 55HEV42288 and 25943, i understand the 55 H part but after that what does it mean and which part is the eastings and which are the northings i have tried many combinations and they are not doing it for me. Can anyone help Thanks Willy
According to the Karen Cody / John Evans website, the co-ordinates use the MGRS grid (military grid reference system) – you’ll find a definition on Wikipedia (http://en.wikipedia.org/wiki/Military_g ... nce_system ). I’ve no idea why this grid would be chosen rather than UTM or Lat/Lon. The given co-ordinate is correctly written as 55HEV4228825943 (ie all together)neilmny wrote:There doesn't seem to be enough numbers wilray. EV should not be part of the co ordinate.
Regarding loading gpx files on a GPS – you don’t need to have any particular grid/datum set. Because the gpx file lists the grid/datum used to create it, your GPS will automatically convert to suit the grid/datum you have set in the GPS.neilmny wrote:Your GPS must also be set for UTM co ordinates to use this type of co ordinate.

The AAWT across the whole Baw Baw Plateau is fine (particularly north of the village turn-off) - it has been cleared by volunteers over the last couple of years.north-north-west wrote:just be aware that some part of the track across the Baw Baw Plateau is always overgrown - usually the stretch north of the Baw Baw village turnoff is the worst
wilray wrote:yes these coordinates you gave me are correct but i was trying to get coordinates for AAWT and when i sourced the above coordinates they did not work, and yes i agree i dont know why the EV is in the coordinates but it is what was there when i accessed link : http://www.johnevans.id.au/Pages/KC/KCAAWT.html and they included all these coordinates supposedly for the track, thought maybe you may understand what it meant. Thanks anyway for trying to help. i will check out the other site you suggest, but if you have a look at the above link you will see what i mean. thanks

However, if you want to take a reference from your GPS to a paper map (or type a reference into a GPS), you need to ensure the grid/datum in the GPS is the same as the map.

Happy hiking and stay safe to you all, cheers willy
Great - well done - and no need to worry about what grid/datum is being used :)wilray wrote:i have done it

Now, are you confident in reading co-ordinates from your GPS and locating that point on your map? That's really what makes a GPS useful.
This comment relates to you having loaded gpx files onto your GPS - there was no need to think about grid/datum settings because the GPS works it out from the information in the gpx file (ie automatically converts the co-ordinates from 'whatever they are in the gpx file' to 'whatever they need to be in the GPS').bernieq wrote:Great - well done - and no need to worry about what grid/datum is being used :)
The reason for this question was to make sure that you (and anyone else reading this) are aware that you DO need to set the GPS grid/datum to be the same as the paper map you are using ....bernieq wrote:are you confident in reading co-ordinates from your GPS and locating that point on your map?
