  2. 2. Introduction Overview •Geography defined •Concepts of Location •Globes, Maps & Map Basics •Geographic Grid
  3. 3. GEOGRAPHY Geo = earth graphy = to scribe, draw, or map
  4. 4. GEOGRAPHY • the science of location •the study of spatial relationships, (context &interconnectedness) •an integrated science that uses knowledge from many disciplines
  5. 5. DIVISIONS OF GEOGRAPHY C U L T U R A L G E O G R A P H Y H u m a n C u lt u r e s U r b a n G e o g r a p h y E c o n o m ic G e o g r a p h y P H Y S I C A L G E O G R A P H Y E a r t h S c ie n c e s B io - g e o g r a p h y W e a t h e r & C lim a t e T E C H N O L O G I C A L G E O G R A P H Y G e o g r a p h ic I n fo r m a t io n S y s t e m s Q u a n t a t a t iv e G e o g r a p h y R e m o t e S e n s in g T H E W O R L D O F G E O G R A P H Y
  6. 6. TOPICAL VS. REGIONAL APPROACH TO STUDYING GEOGRAPHY • Topical or Thematic Studies – climate – vegetation – landforms – hydrology – plate tectonics – soils • Regional Studies – North America – Africa – East Asia – USA – California – Sacramento region
  7. 7. California Geography • Geography: The study of where things are. • California: A political unit with distinct boundaries, and territory • California Geography: the study of the location of, context and interaction of phenomenon within the state of California
  8. 8. Northern Hemisphere Arctic Ocean & North America
  9. 9. Pacific Ocean
  10. 10. Pacific Rim
  11. 11. Western North America
  12. 12. Introduction Overview •Geography defined •Concepts of Location •Globes, Maps & Map Basics •Geographic Grid
  13. 13. LOCATION • Relative Location – location relative to other locations – situation • Exact Location – geographic grid (38 °N 120 °W) • latitude & longitude – site • Place Names – labels for locations
  14. 14. Introduction Overview •Geography defined •Concepts of Location •Globes, Maps & Map Basics •Geographic Grid •California Overview
  15. 15. GLOBES & MAPS • Globe: a spherical model of the earth that maintains area, shape distance & direction • Map: a flat representation of a globe that allows distortion
  16. 16. MAP BASICS • Maps may show –Shape of objects –Area of objects –Distance to Objects –Direction
  17. 17. MAP BASICS • Maps must include –Title –Legend or Key –Compass Rose –Scale
  18. 18. SCALE • Scale: the relationship between units on the map and actual distance on the ground • Written Scale: one inch equals one mile • Linear Scale: |---------|---------|----------| • Ratio Scale: 1:63,360
  19. 19. Introduction Overview •Geography defined •Concepts of Location •Globes, Maps & Map Basics •Geographic Grid
  20. 20. Latitude GEOGRAPHIC GRID A system of measurements from reference points that allow us to locate places
  21. 21. GEOGRAPHIC GRID • REFERENCE POINTS • Equator - A great circle that divides the globe into two equal halves or hemispheres of north and south. Located at 0 ° latitude • North and South Poles - located at right angles or 90° from the plane of the equator.
  22. 22. GEOGRAPHIC GRID • REFERENCE POINTS • Prime Meridian: The meridian, designated as 0° E, W longitude, that passes through the Royal Observatory at Greenwich, England. • International Date Line: An arc that follows 180° longitude E,W. When crossing the date line, the calendar is turned forward or backward one day, depending on direction of travel.
  23. 23. Latitude Latitude - angular measurement north or south of the equator
  24. 24. Latitude Longitude- angular measurement east or west of England
  25. 25. Parallels are circular lines used to indicate latitude Meridians are arcs used to
