Map Projection (SUR314) - Quiz 1

What is a map projection?

• A technique to create virtual maps

• A method to flatten the Earth's curved surface onto a flat surface

• A way to enhance the colors of a map

• A process of creating 3D maps

Which of the following statements best defines a map projection?

• A map that is projected onto a screen

• A transformation of the Earth's surface onto a flat map

• A map with accurate colors and shading

• A representation of the Earth's surface in a globe format

What are geographic coordinates?

• Lines drawn on a map to indicate boundaries

• The distance between two points on a map

• A system of latitude and longitude used to locate points on Earth's surface

• The ratio of the map's scale to the actual distance on the Earth

What is the scale factor in map projection?

• The size of the map projection

• The ratio of the map's scale to the actual distance on the Earth

• The degree of distortion in a map projection

• The accuracy of the map projection

What is distortion in map projection?

• The process of flattening the Earth's surface onto a map

• The change in colors and shading on a map

• The stretching, shrinking, or skewing of features on a map

• The process of dividing a map into different regions

• The map projection preserves shape

• none of the above

In map projection, what does the term "conformal" mean?

• The map projection preserves areas

• The map projection preserves shapes

• The map projection preserves distances

• None of the above

What is the purpose of the scale factor in map projection?

• To adjust the size of the map

• To determine the type of projection

• To calculate the distortion on the map

• Distorts areas near the center of the projection

• Represents great circles as straight lines

• Represents parallels as straight lines
