Maps: The Geographer’s Basic Tools

An Introduction to Mapping

1. Parts of a Map – Map Symbols– Mapping Your Location

2. Types of Maps – Grid Systems– Topographic Map Study

3. Using Latitude and Longitude

4. Political Map of Canada (already completed!)

5. Pear Island Mapping Exercise

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)

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

Text Assignment

• Use your textbook and your text assignment to answer Qs #4-7

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
