1. What is a Map?
• A map is a representation of the Earth’s features drawn on a flat surface.
• Maps use symbols and colours to represent features of an area, simplifying the real world.

Features on a Map
• A. Title – identifies the area shown, topic, focus, or purpose of the map
• B. Legend – explains the meaning of symbols and colours used on the map
• C. Scale – represents the relationship between distance on the map and distance in the real world
• D. Direction – often represented with an arrow • E. Border – sets the map apart from other
information• F. Date of Publication – indicates how recent
the map is

What are the points on a compass for?
• A compass is a way of finding direction
• The four cardinal points are N, E, S, W
• The points all have corresponding degrees of a circle (0° → 360°)

Types of Maps
• Road Maps
– Mostly use alphanumeric system (like Battleship!)
• Topographic Maps
– Use military grid system (4 numbers or 6 numbers)
• Thematic Maps

Types of Maps
• Road Maps– A map drawn to scale using symbols and colours to
indicate major highways and roads for transportation purposes
– Often other features are shown on road maps such as parks, hospitals, and tourist attractions
– Can be both small scale (a country map) and large scale (a city map)
![Page 8: CGC1D – Gr. 9 Geography of Canada Maps: The Geographer’s Basic Tools.](https://reader035.fdocuments.in/reader035/viewer/2022062407/56649f585503460f94c7e607/html5/thumbnails/8.jpg)
Types of Maps
• Topographic Maps– A map that indicates scale, using symbols and colours
for both natural and human features on the Earth’s surface
– Shows the Earth’s surface in great detail (large scale)– Depicts the height of land features (topography)– Often shows roads, settlements, vegetation cover,
power lines, etc.

Types of Maps
• Thematic Maps– A map that reveals the geographic patterns of
statistical data– Usually focuses on one
theme or topic (e.g. population distribution)
– Are designed to display distributions over the Earth’s surface

Lines on the Earth
• Latitude– imaginary lines that measure the distance north or
south of the Equator (0°)– lines are parallel to the Equator at regular intervals
(approximately 111 kilometres apart)

Lines on the Earth
• Longitude– imaginary lines that measure the distance east or
west of the Prime Meridian (0°)– all lines begin and end at the poles and therefore are
not at a fixed distance apart– the Prime Meridian (0°) was arbitrarily chosen at a
point that runs through Greenwich, England– the International Date Line (180°) is the point where
one day begins and one day ends

Scale
• Direct Statement Scale uses words to describe what a distance on a map represents in the real world
• 1 cm = 10 kilometres
– Linear Scale uses a special ruler on a map to show what a distance on a map represents in the real world
• 0 km 400 km
– Representative Fraction Scale is a ratio where one unit on a map represents a specific number of the same unit in the real world
• 1:50 000 (1 cm on the map represents 50 000 cm, or 0.5 km in the real world) to help you convert remember that 1 km = 100 000 cm
