Map Projections and Remote Sensing

What is the main purpose of map projections?

• To create a three-dimensional representation of the Earth

• To remove distortion in size and shape of land masses

• To accurately depict the cardinal directions

• To navigate marine travel

What is the advantage of the Mercator map projection?

• Accurate depiction of ocean

• Minimizes distortion in size and shape

• Easy navigation with precise direction

• Maintains equal area for all land masses

What is the disadvantage of the Mercator map projection?

• Creates bias in perception of developed and less developed countries

• Distorts the size of land masses near the poles

• Difficult to interpret information

• Interrupts the land masses

Which map features are used to find locations?

• map legends

• contour lines

• latitude & longitude lines

• map scales

Which mapping option shows differences in elevation of the land?

• cylindrical

• geologic

• topographic

• conical

How are remote sensing data commonly used?

• predict surface geology

• monitor changes in land

• change contour intervals

• they are not used
