Oziexplorer Map allignment

Can you provide more info about the types of maps you are using?
Where did you get the .map files from?
If you picked the wrong Australian datum I would expect errors of up to 200 metres to the north and the east, not 200 km.

I got the map "Australia Political_OZF.map" from Oziexplorer website, it only has 2 calibration points, how do you make more calibration points? 1st on at the ashmore reef where lat and long lines meet, 2nd near Bendigo where lat and long lines meet.

Hi Graham,

I downloaded that map and it is not all that ideal due to its low detail and lack of lat/long lines. However I did load some of my waypoints and tracks and they are relatively close to the mark give or take 50km or so.

When in the calibration screen, to add more calibration points just click on the 'Point 3' tab on the right which will bring up some cross hairs where your mouse cursor used to be. Move this to where the lat/long lines cross and click as close as possible on it. Enter your lat/long co-ordinates in the boxes and repeat for 'Point 4' and 'Point 5'. Try and zoom in as close as possible for more accuracy. I usually have one in each corner of the map and one in the centre. The more you have, the more accurate (or less errors) you will be/have.

In configuration I have my datum set to WGS 84 wherever it has this option.

Regards
David
