1 Ch 1 Latitude and Longitude pp

2 Vocabulary Relative Location – general location of a place described in terms of distance and direction from another place. Absolute Location – the exact location of a point on the earth’s surface identified by coordinates (latitude, longitude). Global Positioning System – technology that uses satellite to give precise location of any place on earth’s surface.

3 Vocabulary Cultural features – feature on earth caused by human activity – city, roads, bridges, etc. Physical features – feature on earth caused by natural forces – river, oceans, sand dunes, forests. Topographic map – map which shows surface features of a region, both cultural and physical.

4 Vocabulary Small-scale map – map showing a small amount of detail – provincial road map. Large-scale map – map that shows a large amount of detail – city road map.

5 Ch 1 Latitude and Longitude 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.

6 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 0 o. The greatest distances are the North pole, 90 o N, or the South pole, 90 o S.

7 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 0 o longitude.

8 Ch 1 Latitude and Longitude latitude and longitude

9 Ch 1 GPS 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.

10 Ch 1 GPS 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.

11 Ch 1 GPS Uses: Tracking wildlife Weather patterns Navigation Military Vehicle tracking Emergencies – fire, police, ambulance Child find Monitor criminals
