Presentation Transcript

  1. Small Scale Map

  2. Large Scale Map

  3. Map Scale Bar

  4. Common Map projections

  5. Azimuthal

  6. Azimuthal • Shows direction accurately • Distorts shape • Often used for polar regions

  7. Mercator

  8. Mercator • Gives true direction • Land shapes fairly accurate • Size and distance are distorted-polar areas

  9. Robinson

  10. Robinson • Minor distortions at north and south poles • Shape and area of continents and oceans is fairly accurate

  11. Homolosine

  12. Homolosine • Continents close to their true sizes and shapes • Distances are not accurate

  13. Winkel-Tripel

  14. Winkel-Tripel • Modified Robinson projection • Less distortion of area and shape
