APHG Unit 1 Topic 1.1: Cartograms, Absolute vs. Relative, and Time-Space Compression

by Brittni Beeson

​Today's Objective

• ​I can identify the different types of maps and data presented on those maps.

​Types of Maps Data

​Cartograms Absolute vs. Relative Location

​ Time Space Compression Distance Decay

​

​Do Know

​Identify Types of maps

​ Data

​Topic 1.1

• ​Cartograms

• ​Absolute vs. Relative Location

• ​Time Space Compression

​Cartogram

What difference do you see in the two maps and why is there a difference?

Cartogram Map- a a map in which the size of a region or territory is in proportion to data the map shows, whether it's land area, population, or amphibians.

​Cartogram Map

​Cartogram is a map in which the geometry of regions is distorted in order to convey the information you are looking for. The area on the map will be inflated (bigger) or deflated (smaller) according to its numeric value.

​

​Look at the image on the next page of a 'world population cartogram' and in particular look at how big India is. This is because it has a big population.

Multiple Choice

A cartogram map looks strange because:

• there are very few points of reference 

• the we are not used to looking at them

• the country size is bigger or smaller depending on the data you are looking at

• the colours chosen always clash with each other

How does the cartogram data change as time goes by? Why?

​Absolute vs. Relative Location

Absolute Location

• Describes where something is absolutely

  • examples:

    • address

    • longitude and latitude

      • Ms. Neilson is currently located at: 994 Andrews Ave, Ozark, AL 36360 in room 111 in the north east corner of her classroom.

Absolute Location

Includes:

Coordinates

Address

An exact location.

Multiple Choice

Which of these is NOT absolute location?

• across the street from the old oak tree

• an address

• longitude and latitude

Relative Location

• Tells us where something is in relation to something else.

  • ​examples

    • Across the street from the cemetary

    • next too room 113

    • down the hall from Mrs. Aponte's classroom

    • To the the right of McDonalds

Relative Location

• General area

• Normally used when giving directions to a person. (Turn at the blue building)

Fill in the Blanks

If someone told you their address, this would be relative or absolute location?

Multiple Choice

Antarctica is located south of the Equator is an example of what type of location?

• Absolute

• Relative

Multiple Choice

123 North Main Street, Hanover PA 17327

Is an example of what type of location?

• Absolute

• Relative

Multiple Choice

The specific location on the Earth is an example of what type of location?

• Relative

• Cardinal

• Absolute

Multiple Choice

Northwest of South America is an example of what type of location?

• Absolute

• Relative

Multiple Select

Select all that are a relative location.

• next to the old oak tree

• across the street from Burger King

• across from Ms. Neilson's room

• P. Sherman 42 Wallaby Way, Sydney

​Time-Space Compression

Open Ended

How did the first civilizations communicate with each other?

Open Ended

Think: Has communication changed in the world with the advancement of technology such as the internet, etc.?

​Distance Decay

• ​the further away someone is from another, the less likely the two are to interact

• ​​contact decreases with increasing distance and eventually disappear

  • ​example: being closer to family that lives closer

​Time-Space Compression

• ​The reduction in the time it takes for something to reach another place

  • ​example: mail travels faster through email versus snail mail or the postal service

​Tobler's 1st Law of Geography

• ​According to Waldo Tobler, "everything is related to everything else, but near things are more related than distant things."

That is all folks!​
