Map Distortion

Identify this projection

• Robinson
• Winkel Tripel
• Polar
• Mercator

All map projections are somehow incorrect.

• True
• False

Why does distortion occur on every map?

• Cartographers are politically biased.

• GIS technology encourages errors.

• The 3D world cannot be accurately converted to 2D

Who would be most likely to use this projection?

• Ship Captains

• Pilots

• Meteorologists

• Teachers

Why does Google maps use the Mercator projection?

• Direction is easier to navigate a grid & distortion decreases when zoomed in

• The size and shape of continents is more accurate.

• It is easy to calculate mileage.

• Because all of the Earth can be seen on the Mercator

Cardinal Directions

• The planet is divided into these four sections

• a small, sphere shaped model

• When an object loses its original size and shape

• North, South, East, and West
