GST 101 - Module 3 Self-assessment Quiz

1. A standard point or line is the location on a map projection where there will be no scale distortion.

True

False

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.

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.

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

True

False

Spherical coordinate systems do not ignore the curvature of the Earth.

Explanation

Spherical coordinate systems do not ignore the curvature of the Earth.

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

True

False

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.

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.

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

True

False

Latitude lines measure North-South +90°N to -90°S.
Longitude lines measure East-West +180°E to -180°W.

Explanation

Latitude lines measure North-South +90°N to -90°S.
Longitude lines measure East-West +180°E to -180°W.

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

True

False

A conformal map projection preserves size relationships on a map.

Explanation

A conformal map projection preserves size relationships on a map.

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

True

False

Datums allow us to connect coordinate systems to the measured shape of the Earth.

Explanation

Datums allow us to connect coordinate systems to the measured shape of the Earth.

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

True

False

It is impossible to display anything that is round on a flat surface without creating some sort of distortion.

Explanation

It is impossible to display anything that is round on a flat surface without creating some sort of distortion.

8. Latitudes are also known as Meridians.

True

False

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.

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.

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

True

False

A secant line touches a sphere at two locations. A tangent line touches a sphere at one location.

Explanation

A secant line touches a sphere at two locations. A tangent line touches a sphere at one location.

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

True

False

There are four map projection properties, area, shape, distance, and direction.

Explanation

There are four map projection properties, area, shape, distance, and direction.
