Cornell Notes--Maps
Models
• Models are representations of real objects or systems– Allow us to manipulate things that we can’t work with in
real life.– Allows us to predict what would happen under different
conditions or in the future.• Physical models= a 3 dimensional representation used to
show relationships between parts.– Model solar system
• Conceptual models= a diagram that shows how the parts of a larger whole are related.– Food web
• Mathematical models =based on mathematical equations.– Population next year=(This year’s population+ all births+all people
moving in)-(all deaths+all people moving out).
What types of models do we make of the Earth?
• Globes are physical models that represent the Earth’s surface.
• A map is a flat representation of the curved surface of the Earth.– A conceptual model of the Earth’s surface.
Cartography
• Cartography is the science of map making.• Cartographers are scientist who make maps.– Collect data from a lot of sources• Surveys• Remote sensing—the process of gathering and
analyzing information about an object without being able to physically touch it.

How do we make maps?
• The problem is that it is hard to transfer a curved surface to a flat format.
• Map projections –a flat map that that represents the curved surface of the earth.
• Distortions always happen in map projections.
Types of Map Projections
1. Cylindrical• A cylindrical projection
map is the most common type of map that we see. Imagine placing the movie screen around the globe in a cylinder shape. The projection that results is depicted in this image. Notice that areas close to the equator have very little distortion. However, the closer to the poles that one travels, the more distorted the map becomes. In this example, Greenland appears to be many times larger than it really is.
Types of Map Projections
2. Conic• A conic projection
map is created by placing a cone shaped screen on a globe. The resulting projection is more accurate than the cylindrical projection map discussed above. However, the further we travel down the map, the more distorted and less accurate the map becomes.

3. Planar/Azimuthal• A plane projection is
created by placing an imaginary screen directly above or below a globe. The image that would result is called a plane projection. This type of map projection is not commonly used.

What are maps used for?
• There are all sorts of maps. Here are a few.Road mapsWeather mapsSatellite mapsGeologic mapsSoil mapsTopographic maps.
Road maps
Weather maps
Satellite maps
Geologic maps
Parts of a map• Compass directions• Symbols with
legend(list of map symbols and their meanings)
• Scale(the relationship between the distance on the map and the actual distance)
Topographic Maps
• Topographic maps– Shows the surface shape(topography) of the land.– Uses lines called contour lines to connect areas of
equal elevation(height above sea level).• Isograms-line on a map that represents constant or
equal values.– Example: Isobars connect areas of the same pressure on a
weather map.– Contour interval-the difference in elevation between contour lines.– Relief-the difference in elevation between the highest and lowest
point on the map.
