Why do we need maps
Population size
Mountain heights (to see the terrain)
City/Country size
Water bodies
Weather patterns
Animal Habitats
Natural Disaster centers
Navigation and Direction
Orienteering
If your GPS dies, because your GPS needs 3 satellites (to triangulate, latitude, longitude, altitude)
Types of Maps
General reference (Daily Basis Map), Topographic, Navigational, Cadastral (Property Line Map), Thematic, Political Map (Country)

Canada’s Mojor water bodies
Hudson Bay → Hudson Strait
Bay of Fundy
James Bay → Tail of Hudson Bay
Georgian Bay → Near Great Lakes but it isn’t a Great Lake
Davis Strait
Great Bear Lake & SLave Lake → In Northwest Territories and is important to the Indigenous
Lake Ontario - G L
Lake Michigan - G L → Drips into Michigan

Lake Superior G L
Lake Huron G L
Lake Athabasca → Saskatchewan
Mackenzie River → Goes into Peace River
Fraser River → British Columbia
St Lawrence River
Nelson River → Drains Hudson Bay
Ottawa River
How do waterways benefit Canada
We’ve had clean drinking water since the beginning
Provide passage for goods/products internationally (Not Landlocked)
Transportation (cruises, immigrants, medical aid)
Leisure activities (boating, waterskiing, kayaking)
Historical perspective (Discovered new lands and countries)
Provides abundance of seafood (crabs, fish, lobsters, etc.)
Migration and settlement patterns (People migrated towards water)
Canada’s economy has exploded due to its waterways (International market)
Who was the first person to use a grid
Ptolemy
Latitude
Latitude lines run horizontally and are called parallels
Each degree is approximately 111km apart (slight variation because of earth’s egg shape, called the Mercator Projection, or Greenland problem)
The latitude of the north pole is 90* N and the south pole is 90* S
Types of scale
Verbal Scale: Gives maps scale with words
1cm = 5km
Linear Scale: Line bar divided into units, represents real distance
Ratio Scale: Shows scale using ratio
1:50, 000
What is a contour line
Shows the elevation of the land, elevating is the height of the land above sea level
Meters and feet are commonly used as units to measure elevation
Who needs contour lines
Hikers - risk of hike
Rock Climbers - danger of climb
Tourists - altitude sickness, acclimation
Military - so they know what they’re walking into
Pilots - so they don’t fly into mountains
Contour Rules
Never cross
Are continuous
All points on a contour line have the same elevation
Lines close together represent a steep slope
Lines far apart represent a gentle slope
(mostly brown)
Military Grid
A 6 or 4 point grid reference used to locate places, 6 is more accurate and 4 is slightly vague
Map grid rules
Each line has a 2 digit number
Add a zero before single digits
Each square is 1 sq kilometer
Lines that go north and south are called northings
Lines that go east and west are called eastings
Topographic
are made for reference and navigation purposes and include both natural and man-made features
Use symbols, colors, and lines to represent things like…hospitals, cemetery, highways forests, swamps, orchards, residential vs industrial areas, churches, stadiums, bodies of water
The three types of symbols on topographic maps are area symbols (large areas of land, illustrated with color or symbols. Examples include marshes, deserts, orchards, forests, tundras, etc), line symbols (Linear feature. Examples include roads, highways, ricers, railroad tracks, etc), and point symbols (represent a specific location/ building. Examples include hospitals, schools, churches, stadiums)
Thermatic
Focuses a specific theme or specific theme or subject area (Examples include physical social political cultural, economic, sociological, agricultural, etc)
Physical
A physical map shows the physical features of an area.
It also provides readers with information about the topography, or the height, depth, and shape, of these features.
Physical maps identify mountains, deserts, bodies of water, and other landforms.
General Referance
An example of this would be a map for an amusment park
provides you with general referance to the area
Cadastral
show all the boundaries of different parts of land pieces based on their length, area, and direction.
With these maps, you can view the ownership status of land pieces in different regions based on your requirements.
