Latitude and Longitude coordinates are often presented in degrees, minutes, and seconds, such as 39° 45' 30" (39 degrees, 45 minutes, 30 seconds). However, Golden Software programs can only plot values in decimal degrees. So, for example, 39° 45' is referred to as 39.75° in MapViewer, Surfer and Didger. Golden Software programs do not currently have a way to do this conversion, and the conversion must be done manually.

Converting from degrees, minutes, and seconds is actually quite easy. Consider the latitude value 39° 25' 30". This value needs to be converted to use it in Golden Software programs. There are 60 minutes in one degree and 3600 seconds in one degree. To convert minutes and seconds to decimal degrees, divide minutes by 60, divide seconds by 3600, and then add the results to obtain the decimal equivalent.

Use the following formula to make the conversion:

Decimal degrees = Degrees + Minutes/60 + Seconds/3600

For Example:

To convert 39° 25' 30" to decimal degrees

1. First, convert minutes and seconds to their degree equivalents and add the results
25'/60 = 0.4167°
30"/3600 = .0083°
and 0.4167° + 0.0083° = 0.425°

2. Then, add this number to the number of degrees.
39° + 0.425° = 39.425°

3. So, the final result is:
39° 25' 30" = 39.425°

Once your coordinates are in decimal degrees, you can use the data in Golden Software programs.

See attached Excel sheet for an example.
