​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

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.

​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.

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)

​Time-Space Compression

​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!​
