Chapter 1 – Finding Your Way Atlantic Canada Consists of 4 provinces Province Prince Edward Island Nova Scotia New Brunswick Newfoundland & Labrador Abbreviation PE NS NB NL Capital Charlottetown Halifax Fredericton St. John’s Finding Location Using Latitude and Longitude Known as the universal language of location Any spot in the world can be located Especially important for use on the sea A grid system of imaginary lines found on maps and globes Lines of Latitude are drawn east-west show distances north or south of the Equator (0°) greatest distance = North Pole (90°N) and South Pole (90°S) Lines of Longitude are drawn north-south show distances east or west of the Prime Meridian (0°) greatest distance = opposite side of globe in mid-Pacific ocean (180°) Measured in degrees and minutes Includes a direction (N/S for latitude & E/W for longitude) Using latitude and longitude gives you the absolute location of any spot in the world Having only a general idea about where a place is located is called relative location Finding Location with the Global Positioning System (GPS) In the past, calculating latitude and longitude was complex Today, it’s easy because of technology (quick & accurate) GPS = satellites that give the precise location of any place on earth Need at least 3 satellite signals to work Finding Places from the Air Satellite maps provide pictures of enormous regions of Earth Takes a satellite about 103 minutes to make a complete rotation of the earth Provides a view of both physical and cultural features Physical Features features caused by natural forces rivers, valleys, mountains Cultural Features features made by humans or human activity farms, buildings, roadways, bridges Finding Your Way with a Topographic Map a very detailed map that provides the reader with many facts has a key to explain the symbols and colors Includes: Physical features – shows lakes, forests, hills, valleys, etc…, shows wooded areas in green and water areas in blue Cultural features – buildings, attractions, bridges, etc…, uses symbols to represent each item (tent = camping, oval = track) Elevation or height of the land Location – uses a grid system similar to latitude and longitude, but is read in a different way. Numbered lines appear on both the top/bottom and right/left side of the map. Each line is numbered and the space in between is divided into tenths. First, we read the east-west (across) number, and then the north/south (up & down) number. Together they make a 6 digit code. Example: 88 and 7 tenths = 887 41 and 6 tenths= 416 Together = 887416 Finding Your Way Downtown In built up areas (towns, cities) we use street maps They show a large amount of detail Large-scale map shows a lot of detail (on one map - streets, parks, buildings, attractions, etc…) Small-scale map shows only a little bit of detail (a different map for each task – roads, provinces, countries)
