Transcript

  • 1. Map Skills Definitions and Examples
  • 2. Globe • ~a model of Earth.
  • 3. Hemisphere • ~one-half of the globe • The Equator divides the Northern and Southern hemispheres. • The Prime Meridian divides the Eastern and Western hemispheres.
  • 4. Latitude • ~locations north or south of the Equator measured by imaginary lines. • The Equator is at 0 degrees latitude; an imaginary line that separates the northern and southern hemispheres.
  • 5. Longitude • ~locations east or west of the Prime Meridian, measured by imaginary lines. • The Prime Meridian lies at 0 degrees longitude.
  • 6. Grid System • ~the checkered board pattern on a map that is created by crossing lines of latitude and longitude. • This grid system helps you find the absolute location of a place.
  • 7. Absolute Location • ~the specific location of a place; the longitude & latitude of a location or the specific address of a location. • For example; MMS Currituck County 216 Survey Road 36.36 degrees N, Moyock, NC 27958 75.94 degrees W
  • 8. Projection • ~how mapmakers draw the round earth on a flat piece of paper. • Mapmakers create many different map projections, that have their own unique characteristics.
  • 9. Map Key • ~ a code that explains lines, symbols, and colors used on a map.
  • 10. GIS • ~a computer software program that mapmakers use that can help them make and change maps more quickly and easily than before. • G-geographic I-information S-systems
  • 11. Cardinal Directions • ~ basic directions on a compass rose. • N (north), E (east), S (south), W (west) This compass rose only shows cardinal directions.
  • 12. Compass Rose • ~a device drawn on maps to show directions.
  • 13. Intermediate Directions • ~any direction between the cardinal directions. • For example, NE (northeast) is between north and east. This example shows both cardinal and intermediate directions.
  • 14. Scale bar • ~a measuring line on a map that helps you determine distances on a map.
  • 15. Scale • ~the ratio between a distance on a map and the same distance on the earth. • For example; 1 inch:20 miles
  • 16. Relief • ~changes of elevation over a given area of land This is an example of a raised relief map.
  • 17. Elevation • ~the distance of an area above sea level.
  • 18. Contour lines • ~one line for each major level of elevation: contour maps show levels of elevation: contour maps are a type of physical map
  • 19. *Relative location* • ~the location of a subject in relation to another point. • For example; Camden County is just west of Currituck County.
  • 20. *Review* • How are political and physical maps different from each other? • Compare how they are the same…
  • 21. Political Maps • ~show the names and boundaries of countries and often identify major physical features
  • 22. Physical Maps • ~ identify landforms and water features Physical maps often show relief or elevation. A contour and relief maps are physical maps.
