Compass Rose What do you know about directions?

N- Never (North) E – Eat (East) S – Soggy (South) W – Wieners (West)

These are the four principal or Cardinal points found on the compass rose. This might be great for travelling up to Grand Beach or out to Toronto, but what about all of those other places in between?

Page 3: Direction and Grid Systems

Compass Rose There is a set of ordinal points found halfway

between each cardinal point called the ordinal points. These indicate

NE –North-East NW – North-West SW – South-West SE – South-East

Page 4: Direction and Grid Systems

Compass Rose There is a further subdivision between the

cardinal and ordinal points that indicate directions such as North-North East that can be found between North and North-East.

NNE SSW ENE WSW ESE WNW SSE NNW

Compass Rose Degrees, from 0˚-360˚, on the compass rose,

called compass bearings, provide a more accurate direction than Cardinal Points because they measure the angle of the direction in relation to the North, moving in a clockwise direction.

Alphanumeric Grid System Have you ever used a Winnipeg transit map to

get anywhere in the city?

Winnipeg Transit uses alphanumeric maps to show the public their routes throughout the city.

Alphanumeric Grid System

Alphanumeric grid maps are maps that use both letters and numbers to identify squares in a grid pattern.

The letters are found on one side of the map, while the numbers are found on the other side.

Alphanumeric grid maps are often used on road maps.

Map (Military) Grid System The Map Grid, or Military Grid System was

developed and used by Britain in WW1

Vertical lines run from top of the map to the bottom of the map called easting. These vertical lines are numbered with a 2 digit number.

Eg. 81/82/83 The number refers to the column to the right

of the vertical numbered line.

Page 14: Direction and Grid Systems

Map (Military) Grid System Horizontal lines run across the map from the

left of the map to the right called northing. These horizontal lines are also numbered with a 2 digit number.

Eg. 09/10/11 The number refers to the row above the

horizontal numbered line.

To identify the square on the map, combine the easting and northing numbers.
