GEOG 131 Lecture Notes - Lecture 2: Geographic Coordinate System, Great Circle, Concentric Objects
Document Summary
19 august 2016: geographic coordinates, parallels latitude a. i. Run east and west but measure north to south a. iii. 1. a. iii. 2. a. iii. 3. a. iii. 4. a. iii. 5. 0 degrees at equator, 90 degrees at pole. All lines north are north latitudes (0 to 90 degrees n)) All lines south are south latitudes (0 to 90 degrees s) a. iv. Equinox is when sun is directly over the equator a. vii. Great circle plane of latitude, all others are small circles: meridians longitude b. i. Determined by plane that passes through poles dividing earth into two equal halves each half of the plane connecting one pole to the other is meridian of longitude. More difficult to determine than latitude b. v. run north and south but measure east and west b. v. 1. b. v. 2. b. v. 3. b. v. 4. 0 degrees at prime meridian, increases east and west. Any point of the earth moves through 360 degrees in 24 hours or 15 degrees per hour b. v. 5.
