Self-assessment quiz for GST 101 - Module 3 - Understanding Coordinate Systems

Questions and Answers
• 1.

### A round Earth can fit without distortion on a flat piece of paper.

• A.

True

• B.

False

Correct Answer
B. False
Explanation
It is impossible to display anything that is round on a flat surface without creating some sort of distortion.

Rate this question:

• 2.

### A spherical coordinate system does not ignore the curvature of the Earth.

• A.

True

• B.

False

Correct Answer
A. True
Explanation
Spherical coordinate systems do not ignore the curvature of the Earth.

Rate this question:

• 3.

### Latitudes are also known as Meridians.

• A.

True

• B.

False

Correct Answer
B. False
Explanation
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:

• 4.

### The State Plane Coordinate System is a 2D Cartesian Coordinate System.

• A.

True

• B.

False

Correct Answer
A. True
Explanation
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:

• 5.

### A secant line touches a sphere at one location.

• A.

True

• B.

False

Correct Answer
B. False
Explanation
A secant line touches a sphere at two locations. A tangent line touches a sphere at one location.

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. True
Explanation
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:

• 7.

### There are three map projection properties: area, shape, and distance.

• A.

True

• B.

False

Correct Answer
B. False
Explanation
There are four map projection properties, area, shape, distance, and direction.

Rate this question:

• 8.

### A conformal map projection preserves area relationships on a map.

• A.

True

• B.

False

Correct Answer
A. True
Explanation
A conformal map projection preserves size relationships on a map.

Rate this question:

• 9.

### A datum is a reference surface for measuring locations on the Earth.

• A.

True

• B.

False

Correct Answer
A. True
Explanation
Datums allow us to connect coordinate systems to the measured shape of the Earth.

Rate this question:

• 10.

### Lines of Latitude measure North-South and vary from +90°N to -90°S.

• A.

True

• B.

False

Correct Answer
A. True
Explanation
Latitude lines measure North-South +90°N to -90°S.
Longitude lines measure East-West +180°E to -180°W.
