“Tool Box” Unit
Part 2 – Where are you?
![Page 2: “Tool Box” Unit Part 2 – Where are you?. Global Grid Use the grid to give your coordinate address on earth Absolute Location vs relative location](https://reader036.vdocuments.site/reader036/viewer/2022081501/56649e845503460f94b86422/html5/thumbnails/2.jpg)
Global Grid
• Use the grid to give your coordinate address on earth
• Absolute Location vs relative location

This is the Earth

This is the Earth with Grid

Latitude
• Latitude – Lines that circle the earth east to west, and tell you how far you are north or south of the equator
• The Equator is the zero latitude line that divides the earth into north and south
• Also called parallels

Longitude
• Lines that circle the earth north to south and tell you your position east and west.
• Prime Meridian is the zero longitude line that divides the earth into east and west
• Also called meridians

Hermispheres
• Equator divides earth into North and South• Prime Meridian divides earth into East and
West

Prime Meridian
• Runs through England

Globes vs Maps
![Page 12: “Tool Box” Unit Part 2 – Where are you?. Global Grid Use the grid to give your coordinate address on earth Absolute Location vs relative location](https://reader036.vdocuments.site/reader036/viewer/2022081501/56649e845503460f94b86422/html5/thumbnails/12.jpg)
Different Kinds of Map Projection
• Robinson• Polar / Azmuthal• Goode’s• Mercator• & more……
![Page 13: “Tool Box” Unit Part 2 – Where are you?. Global Grid Use the grid to give your coordinate address on earth Absolute Location vs relative location](https://reader036.vdocuments.site/reader036/viewer/2022081501/56649e845503460f94b86422/html5/thumbnails/13.jpg)
Robinson• Shape and size are both somewhat distorted but not extremely distorted
![Page 14: “Tool Box” Unit Part 2 – Where are you?. Global Grid Use the grid to give your coordinate address on earth Absolute Location vs relative location](https://reader036.vdocuments.site/reader036/viewer/2022081501/56649e845503460f94b86422/html5/thumbnails/14.jpg)
Mercator• One of the simplest projections• One of the more distorted• Shapes are more accurate • size is not accurate
![Page 15: “Tool Box” Unit Part 2 – Where are you?. Global Grid Use the grid to give your coordinate address on earth Absolute Location vs relative location](https://reader036.vdocuments.site/reader036/viewer/2022081501/56649e845503460f94b86422/html5/thumbnails/15.jpg)
Goode’s
![Page 16: “Tool Box” Unit Part 2 – Where are you?. Global Grid Use the grid to give your coordinate address on earth Absolute Location vs relative location](https://reader036.vdocuments.site/reader036/viewer/2022081501/56649e845503460f94b86422/html5/thumbnails/16.jpg)
Polar - Azimuthal
![Page 17: “Tool Box” Unit Part 2 – Where are you?. Global Grid Use the grid to give your coordinate address on earth Absolute Location vs relative location](https://reader036.vdocuments.site/reader036/viewer/2022081501/56649e845503460f94b86422/html5/thumbnails/17.jpg)
Problem….
• Distortion!!!!
• (No, Greenland is NOT as large as Africa!
![Page 18: “Tool Box” Unit Part 2 – Where are you?. Global Grid Use the grid to give your coordinate address on earth Absolute Location vs relative location](https://reader036.vdocuments.site/reader036/viewer/2022081501/56649e845503460f94b86422/html5/thumbnails/18.jpg)
Why?• THE EARTH IS NOT FLAT,
but Maps are!
• This is the answer to a test question…..

IF you could map the round earth….
![Page 20: “Tool Box” Unit Part 2 – Where are you?. Global Grid Use the grid to give your coordinate address on earth Absolute Location vs relative location](https://reader036.vdocuments.site/reader036/viewer/2022081501/56649e845503460f94b86422/html5/thumbnails/20.jpg)
Great Circle Routes….
• Which route is shorter? Kinda seems to depend on which map you look at…….
![Page 21: “Tool Box” Unit Part 2 – Where are you?. Global Grid Use the grid to give your coordinate address on earth Absolute Location vs relative location](https://reader036.vdocuments.site/reader036/viewer/2022081501/56649e845503460f94b86422/html5/thumbnails/21.jpg)
Time Zones….
• Related to Longitude• Earth is divided into 24 zones (because
there are 24 hours in the day…..)• Why should you care about time zones?
– Travel – International business
• Do you realize it’s already tomorrow in Japan????
