Hvem kan hjælpe med at få omsat gamle decca positioner til GPS positioner ?

Hilsen ERIK

Man kan ikke omsætte dem, man kan komme med en rimelig precis omsætning
(inden for et 100-200 meter). Jeg kan godt hjælpe men det kræver at jeg ved
hvor og hvordan decca positionerne er taget.

Hej Erik

Decca always worked in deg min and decimal minutes, the only difference now
is that we have our positions to 3 decimal places not 2.
If you do want to convert seconds into decimal degrees simply divide the
seconds by 60, so 45/60 = 0.75 i.e. 50 36' 45" becomes 50 36.75' Since you
only have 2 decimal places here you would dial that in as 36.750'

Hope it works for you, but I would really check that your originals were in
seconds before you get too carried away!
