1

## Cartographer Definition

### Someone who makes maps

2

## Map Projections Definition

### Special ways of representing the round Earth on a flat surface

3

## What are the 4 properties or features Mapmakers use when they devise a map projection

### Distance, Area, Shape, and Direction

4

## What are the 3 categories a map projection can be group into

### Cylindrical, Azimuthal, and Conic

5

## Cylindrical Projection Definition

### World maps with a cylindrical projection are most accurate near the equator and most distorted near the poles

6

## Azimuthal (Planar) Projection Definition

### Cartographers use azimuthal projections to show polar regions because azimuthal maps are most accurate at the center

7

## Conic Projection Definition

### If you placed a cone over a globe so it covered about half the globe, and then the images on the globe "jumped" onto the surface of the cone, you'd have a conic map projection. Conic projection maps are most accurate around the circle where the globe and cone touch

8

## What is the most famous Cylindrical Projection

### The Mercator projection is probably the most famous cylindrical projection

9

## Why do sailors like the Mercator Projection

### Sailors like to use Mercator maps because a line connecting two points on a Mercator map gives the best indication of the compass direction to follow

10

## What is the problem with the Mercator Map

### The size of the landmasses far from the equator are very badly distorted (For Example Greenland is much bigger than it really is)

11

## Why was the Robinson Projection made

### The Robinson Projection was created to improve upon some of the shortcomings of older projections like the Mercator

12

## What does the Robinson Projection do

### The Robinson minimizes distortion of most of the Earth's landmasses

13

## What type of projection is the Robinson Projection

### Cylindrical Projection

14

## What is the problem with the Robinson Projection

### Because it is a cylindrical projection, however, there is still distortion in the high latitudes

15

## Many cartographers believe what about the Robinson Projection

### Many cartographers think the Robinson projection best represents the size and shape of the Earth's landforms

16

## What does the Goode's Interrupted Homosoline Projection do

### Interrupted projections show the surface of the Earth in segments. The main advantage of an interrupted projection is that it minimizes distortion of the scale and shape of landforms

17

## What is the negative of the Goode's Interrupted Homosoline Projection

### The disadvantage of the Goode's Interrupted Homosoline Projection is that it breaks Antarctica and the oceans into pieces

18

## What type of projection is the Goode's Interrupted Homosoline Projection

### Cylindrical Projection

19

## What does the Miller Projection do

### It avoids scale exaggerations

20

## Why do Mapmakers use the Miller Projection

### To represent the entire Earth in a rectangular frame, mapmakers frequently use the Miller projection (sometimes called the Miller cylindrical projection)

21

## What features are found in the Miller Projection

### It has straight meridians and parallels that meet at right angles

22

## What is the negative of the Miller Projection

### Distorts shapes and sizes and distortion is extreme in high latitudes as is evident with Antarctica

23

## What type of projection is the Miller Projection

### Cylindrical Projection

24

## What is the Mollweide Projection

### The Mollweide projection is an equal-area projection. It has an elliptical shape

25

## Who made the Mollweide Projection

### German mathematician Carl B. Mollweide devised it in 1805

26

## What is the positive of the Mollweide Projection

### The size of landforms is accurate

27

## What is the negative of the Mollweide Projection

### The shapes near the edges are distorted

28

## What type of projection is the Mollweide Projection

### Cylindrical Projection

29

## Who designed the Winkel Tripel Projection

### Another German, Oswald Winkel, designed the Winkel Tripel projection
