Warm-up: What do you think is the title of this map?

“Geo 101”

How to take notes in this class…

Review of Map Basics 1. A book of maps is called: 2. The arrow is pointing at the:

What is this symbol called? The compass rose shows you the cardinal directions (North, East, South, and West) Intermediate NE

What is this called?

What to look for on a map: T: Title O: Orientation (use compass rose) D: Date A: Author L: Legend S: Scale

Types of Maps Reference Political Physical Thematic Examples: – Choropleth – Dot – Graduated symbol – Isoline – Cartogram

Reference Map: Political Major boundaries- countries and states COUNTRIES IN ALL CAPITAL LETTERS State & Cities Not

Reference Map: Physical Physical features – rivers, mountains, elevation

Thematic Map: Choropleth Definition: a map that uses differences in shading, coloring, or the placing of symbols within predefined areas to indicate the average values of a property or quantity in those areas.

Thematic Map: Dot A dot distribution map (also known as dot density map) is as a map type that uses a dotsymbol to show the presence of a feature or phenomenon. Dot maps rely on a visual scatter to show spatial pattern.

Thematic Map: Graduated Symbol A map with symbols that change in size according to the value of the attribute they represent. For example, denser populations might be represented by larger dots, or larger rivers by thicker lines

Thematic Map: Isoline An isoline map is a map with continuous lines joining points of the same value. Examples would be equal altitude (contour lines), temperature (isotherms), barometric pressure (isobars), etc.

Thematic Map: Cartogram a map on which statistical information is shown in diagrammatic form.

Mental Maps Relative Location map of an area, Not to scale

Relative location Describes location of a place in relation to other human and physical features – “New Braunfels is northeast of San Antonio” – Walmart is across the street from Warren H.S. Absolute location The exact position of a place on the surface of the Earth – Coordinates (latitude and longitude) – Address

How do Geographers study the globe? They use an imaginary grid to describe the location of points on Earth. (latitude and longitude)

How do Geographers study the globe? Latitude – drawn in an east-west direction (parallels) Longitude – drawn in a north-south direction (meridians)

How do Geographers study the globe? Divide the world into hemispheres (half of a sphere)

What is the imaginary line that splits the globe into the Northern and Southern hemispheres? A. Equator B. Tropic of Cancer C. Prime Meridian D. International Date Line

The two lines that split the globe into the Eastern and Western Hemispheres are the Prime Meridian and the: A. Arctic Circle B. Tropic of Cancer C. Equator D. International Date Line

How do geographers describe where things are? Read Rubenstein – Key Issue 1 Highlight key terms/ main ideas Answer the learning outcomes on a separate sheet of notebook paper using complete sentences (1.1.1, 1.1.2, 1.1.3)

Warm-up: Tuesday Copy the following words/concepts = quiz on Friday! Geography Cartography Scale Map projection Mercator (projection) Polar (projection) Meridian/longitude Parallel/latitude Greenwich Mean Time TODALS International Date Line Also know: 7 continents 5 oceans

Early Mapmaking Eratosthenes – Greek scientist/ geographer Also calculated the circumference of the Earth!

Map Projections

Picture a globe made of soft clay. Now squash it flat. Congratulations! You’ve just made a map. Sure, you stretched out a few continents, but how else can you depict a round planet on a flat surface? Picture a globe made of soft clay. Now squash it flat. Congratulations! You’ve just made a map. Sure, you stretched out a few continents, but how else can you depict a round planet on a flat surface?

Map Projections How do you take a round Earth & show it on a flat piece of paper? = Map projections (scientific method of transferring locations on Earth to a flat map) All map projections have some sort of Di s t O r T io N – Shape, distance, size, direction

Cylindrical- Mercator Most accurate near Equator Exaggerates lands near the poles Greenland is actually 8 times smaller than South America Africa is actually much larger than the U.S. Is Antarctica REALLY this big?

Conic- Robinson Most accurate around the middle latitudes. Distorts regions that run north- south for long distances. i.e. South America

Polar- Flat - Plane Press the hemispheres into flat circles. Excellent for showing Arctic(left) and Antarctic regions Distortions around the edges

Goode-Homolosine continents that are sized appropriately to one another, but with many interruptions and distortions of distance.
