1. Good morning! Pick up the 3 pieces of paper from the desk thing
Please sit quietly and take out your phone
Take out your 5 Themes notes from yesterday
I will hand back your mental maps at the end of the day

2. Map Projections
What are some differences among these three maps??

3. Planar projections
Project the earth onto a plane that touches—or technically is tangent to---the globe at a single point and you get a PLANAR projection.
Because this projection, also known as AZIMUTHAL projection, is most accurate at its center, it is often used for maps focusing on one of the poles

4. Conic projections
Cap the globe with a cone to achieve a CONIC projection. Cut open the cone and the basis of a map emerges. The map will be at least distorted along the line where they cone touches the sphere. Conic projections are handy for portraying the U.S which fits nicely within the conic shape.

5. Cylindrical projections
Swaddle the globe and project its surface onto a cylinder. Slit the cylinder and flatten it into a map. This projection is most accurate near the equator and greatly distorted near the poles
MERCATOR PROJECTION…distorts continents SIZE
ROBINSON PROJECTION…distorts the SHAPE of the continents

6. Preserving area
To compare geographical data on a level playing field, pick a projection that maintains the correct proportions among the sizes of Earth’s landmasses.
Such a map, often called an EQUAL AREA PROEJCTION, would be useful to demographers.
The price of getting sizes right, however, is distorting the shapes of the continents

7. TYPES of maps

8. Thematic maps
Designed to show a particular THEME connected to specific geographic areas.
Can portray physical, social, political, cultural, economic, agricultural, etc. aspects of any part of the world.

9. Choropleth maps
Progressive shading of regions to indicate degrees of a topic

10. Isoline maps
Lines which join all places with points of the same or equal value
These lines join places with the same or equal characteristics
Height, temperature, pressure, rainfalls
ISO means “equal” or “same”

11. Dot map
Dot distribution (or dot density) uses a dot symbol to show the presence of a feature or phenomenon.
Rely on a visual scatter to show SPATIAL pattern

12. cartogram
A map which adjusts the sizes of countries so as to show the relevance of a topic
