• A mathematical model

• The mathematical model related to real-world features

• A system of coordinates.

• Real-world features are projected with minimum distortion from the round earth to a flat map

• none of the above

What does 'WGS' in WGS84 stands for?

The equipotential surface of the Earth’s gravity field which best fits, in a least squares sense, global mean sea level is called

• Equator

• Datum

• Geoid

• World Coordinate System

When converting Degrees/Minutes/Seconds of latitude in the Northern Hemisphere to decimal degrees

• Add the three values together and divide the sum by 3600, i.e., (Deg+Min+Sec)/3600

• Subtract the seconds from the minutes, then the minutes from the degrees i.e. (Deg-(Min-Sec))

• Divide the Seconds by 3600, divide the Minutes by 60, then add those values to the degrees, i.e. (Deg+(Min/60)+(Sec/3600))

• Multiply the Minutes by 60, multiply the seconds by 3600 and then add all to the degrees, i.e., (Deg+(Min*60)+(Sec*3600))
