25. 5 Lines of Latitude

26. 5 Lines of Longitude

27. What is the importance of
the lines of latitude and
longitude in locating in
maps and globes?

28. BEFORE WE KNOW LAT-LONG:
MARINER’S ASTROLABE
Used to determine the latitude of a ship at
sea by measuring the sun's noon altitude
or the meridian altitude of a star of known
declination.

29. USES OF LATITUDE & LONGITUDE

30. USES OF LATITUDE & LONGITUDE
DIGITAL
MAPPING

31. USES OF LATITUDE & LONGITUDE
AUTO-
MOTIVE
NAVIGATION
SYSTEM

33. 1. Draw a circle which represents the globe.
2. Draw the lines of latitude & longitude intersecting to
each other.
3. Label the five lines of latitude and its measurement.
4. Label the lines of longitude and its measurement.
(Specifically indicate, the prime meridian and the
International Dateline.)

34. • THINK OF THIS! “Compare the
navigational system long time ago, such
as Astrolabe, and the Digital mapping
now which uses GPS (Global Positioning
System).
• STUDY/PRACTICE: Usage of latitude and
longitude in locating places on the map.

43. Looking at the map, what is the
location of the Philippines
using the lines of latitude and
longitude?
• The latitude and longitude of
Manila is 14°North, 121°East

44. How did you locate
the Philippines?
• Use range
• End to end of your
latitude or longitude

45. A system used in geography to
enable every location on earth
to be specified by a set of
numbers(coordinates).

46. How important is the
coordinate system in
locating places on earth?
