Oziexplorer - Datum - Waypoints

Hello - a couple of traps - how are you entering waypoints? I assume manually.

If so the datum used is to a certain extent independent of the datum the map is calibrated in - the display datum (shown in middle, just above top of map) is the datum that will be used for waypoint entry unless you have selected "Datum of Loaded Map" - right click on the area over the display datum name to select option - so match this to the datum of the waypoints you are entering - which may or may not be the "datum of the loaded map" (in your case they are - if they weren’t you would have to select appropriate datum)

Other most common trap is entering wrong format - are the co-ords in metres (eg 345666 mE ) or in decimal degrees (eg 33.12345° S), degrees & minutes (eg 33° 45.59') or degrees, minutes & seconds (eg 33° 45' 35.4").

Some people often mistake

degrees & minutes (eg 33° 45.59').

for

degrees, minutes & seconds (eg 33° 45' 35.4").

so in error (using above example) would enter 59 for seconds when in fact it should be 35.4 (0.59x60).

You can change the format of the lat/long co-ord system by right clicking on the displayed co-ords (extreme left area just above map) to match the ones you are inputting.

Trust this helps

Greg,

You were right on the money!!!. Thankyou very much this has been causing me sleepless nights. I can change the map display as you mentioned but when I go to enter the waypoints it is still in the degrees and minutes format. Is there any way to change this?

I really appreciate your help. Thankyou.
