Latitudes are also known as Meridians.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Latitudes are also known as Parallels. They are called parallels because the latitude lines never touch, unlike Longitude lines (also known as Meridians) that touch at the North and South poles.Rate this question:

The State Plane Coordinate System is a 2D Cartesian Coordinate System.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The State Plane Coordinate System is a 2D Cartesian Coordinate System that covers the United States of America. Since it is a 2D coordinate system, it ignores the curvature of the Earth.Rate this question:

- 6.
A standard point or line is the location on a map projection where there will be no scale distortion.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Standard points and lines are locations where there is no scale distortion. Standard points and lines should be placed at or through locations of principal interest (or center) on the map to display that information with as little distortion as possible.Rate this question:

A datum is a reference surface for measuring locations on the Earth.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Datums allow us to connect coordinate systems to the measured shape of the Earth.Rate this question:
