Question

In python, write a function that converts an input latitude or longitude value in degrees, minutes, and seconds (DMS; no decimals) into decimal degrees (DD). Directions:

• The function should take a tuple containing three numbers representing degrees, minutes and seconds and returns the corresponding decimal degree equivalent.
• You can assume if the degree value is negative all 3 fields are negative. Thus “-30 30 00” is -30.5 degrees, not -29.5 degrees.
• Test your function with some known values before you continue.

Answer 1

def DMStoDD(degree, minutes, seconds):
         
        dd = abs(degree) + abs(minutes)/60 + abs(seconds)/3600

        if degree > 0:
                return dd
        else:
                return -dd

print(DMStoDD(-30, 30, 00))
