Oziexplorer Misbehaving

G'day Paul,

Just to be sure.....
Where did you set the Datums in Ozi?
Did you set it from the main window(under the toolbar), "Select Datum Display"?

Or did you set the GPS to Ozi Dtaum, in the Configuration->GPS...GPS upload/download datum and GPS NMEA datum?

The "Select Datum Display" is to set the datum to match the map dayum.
( I guess you already know that :/ )

The Config datum........well I guess you know that too!

If you post more info about what datum you're using on the GPS (99.99% of the time WGS84 is best!), what map your viewing in Ozi, and what datums you have set in both config uration and the mapping window.

It seems unlikely that Ozi would be having problems with such a small position error, but you never know!

I've been setting waypoints from the mapscreen on my Meridian, and using these to confirm calibrated map images positions.......never had a problem, (that wasn't a result of user input)

cheers.

Even when I go to the 'Names' function and type in for example 'Sydney Harbour' (which has no links to the GPS at all) the plot will show up somewhere to the west of the harbour bridge on the map.

The maps I am using are the NSW Topo and to date their configuration has been spot on.

The datum of the map is WGS 84 and Oziexplorer is set to WGS84 in the 'Configuration'.

Somehow and somewhere I must have changed something but it has me beat what it is I have done.

Cheers

Paul hope I am on the right track but some GPS units have a PCF -position correction factor which you can change and it will automatically add this to the position, if you accidentally changed this it may be putting your position out. I think it should normally be set at zero. hope this helps.

Hi again Paul,
I'd say go to GPSAus, and try to download the 9130_Sydney map.

If you can't download it, it'll be because you may need to have 10 posts (but I'm not 100% sure)

The other option is I could email you a map and Ozi map calibration file, for you to test, but I suspect it'll be the same??

I could send you some waypoints, to check against them!

What version of NSW topo's are you using, I find almost all Aussie maps will be AGD66 or GDA94 .......etc, not many in WGS84. (note WGS84 and AGD94 are the 'same')

Of course, you may already HAVE Festy's NSW topo maps which I think were made in WGS84!
What's the name of the "Sydney Harbour Bridge" map you have?

very strange!

I doubt there is a problem with the GPS!!

cheers.

Thanks for the info. Your co-ordinates are spot on except for the easting; try 151 instead of 210.

The co-ordinates place the plot in the middle of the bridge and yes it is the 'Name, Search' function that is innacurate.

My manually entered points are OK too.

I wonder whether there is anywhere within Oziexplorer where the co-ordinates of the 'Names' can be edited?

Thanks for your help.
