Cultural features – feature on earth
caused by human activity – city, roads,
bridges, etc.
 Physical features – feature on earth
caused by natural forces – river, oceans,

and physical.

Vocabulary
Small-scale map – map showing a small
amount of detail – provincial road map.


Vocabulary
 Lines
of latitude and longitude
are a universal language of
location. We can use these lines
to pinpoint a specific location on
the earth’s surface.
Ch 1 Latitude and Longitude
 Lines
of latitude are drawn east
– west, circling the globe, to
show distances north or south of
the equator. The equator has a
latitude of 0o. The greatest
distances are the North pole,
90oN, or the South pole, 90o S.
Ch 1 Latitude and Longitude
 Lines
of longitude run north –
south pole to pole. They are
used to measure distances east
and west of the Prime Meridian.
The Prime Meridian passes
through Greenwich, England. It
measures 0o longitude.

Ch 1 Latitude and Longitude

In the past, latitude was calculated by
measuring in degrees, the height of the
North Star above the horizon. Longitude
was calculated by finding out the local
time, using the position of the sun, and
then comparing it with the local time in
Greenwich, England. Greenwich time was
recorded on a timepiece called a
chronometer which they carried with
them.

How GPS Works
Today we use GPS, or Global Positioning
System.
GPS consists of a fleet of satellites that orbit
the earth twice a day to give the precise time
and location of any place on the earth. The
GPS receiver gets a signal from at least 3
satellites. The receiver calculates the
distance to each satellite, and then can
determine the absolute location.
