Question

As we learned in the lecture, computer software uses decimal degrees (DD), as they are much easier to handle in complex algorithms for various mapping applications. Your task is to convert Lat-Long from DMS to DD and vice versa. Remember: when using DD, the cardinal direction are replaced by positive and negative numbers . The "+" sign is omitted (it is implied) and only the minus sign "--" is mandatory . (See lecture)

Washington Monument in DC has the following coordinates, in DMS:

LAT: 38 deg 53 min 22 sec North ; LONG: 77 deg 02 min 19 sec West.

Use an online converter (such as https://www.latlong.net/degrees-minutes-seconds-to-decimal-degreesLinks to an external site.) and find the coordinates in decimal degrees.

Choose the correct coordinates in DD for the Washington Monument:

38.88944444 , 77.03861111

38.88944444 , --77.03861111

--38.88944444 , 77.03861111

--38.88944444 , --77.03861111
