WCED WEEK 2 PART 1

TOPIC

Maps, Plans and Scales

2

media

*Scale that uses line segments of a certain length to show the scale on the map

*Skaal wat lynsegmente van `n spesifieke lengte gebruik om die skaal op die kaart te verteenwoordig

​1) Barscale/Staafskaal

3

media

*Scale that compares the length measured in the same units

*Skaal wat gemeete lengtes in dieselfde eenhede vergelyk

(in die geval cm)

​2) Number scale/

Numeriese skaal

4

media

*Diagrammatic representation of an area of land showing landmarks like cities, roads, islands, etc

*Diagrammatiese voorstelling van `n area op die grond wat landmerke soos stede, paaie, eilande ens. wys.

​3) Map/Kaart

5

media

*consist of a net of squares that is drawn across a map

*Bestaan uit klomp vierkantige nette wat oor `n kaart getek is

​4) Grid / Ruit

6

media

*maps designed to show limited terrain in the shape of a strip used to determine distances

*Kaarte wat gebruik word om n beperkte terrein te wys in n strook. Dit word gebruik om afstande te bepaal

​5) Strip map / Strookroete kaart

1) the distance between two buildings in a town on a map measure 4.8 cm on a 1: 20 000 map. what is the distance on the ground in meters

Scale Example calculations

8

media

1) 1: 20 00 means that one unit on the map = 20 000 units on the ground

= 4.8 cm x 20 000 = 96 000 cm

= ÷ by 100 to get to m

= 96000 ÷100 = 960 m

2) Olie besoedeling affekteer 40 km van die kuslyn en hou n groot bedreiging vir die pikkeweinbevolking in.

a) Hoeveel km sal 1 cm op die kaart verteenwordig indien die skaal

1: 50 000 is?

b) What is the length of the oil spill on the map in centimeters?

Scale Example calculations

media

10

2a) 1: 50 000 beteken dat 1 eenheid op die kaart verteenwoordig 50 000 eenhede in die werklikheid.

*skakel 50 000 cm om na km.

*1 cm op die grond verteenwoordig

= 50 000÷ 100 000 = 0.5 km

2b) 40 km kan voorgetsel word as 40 ÷ 0.5

=80 cm op die kaart

1a) Gebruik 'n leniaal om die afstand tuussen Kimberley en Johannesburg te meet

b) use the bar scale to determine the actual distance between the two towns

c) Gebruik n leniaal om die afstand tussen Kaapstad en Durban te meet.

d) use a bar scale to determine the actual distance between the two towns.

Calculations of maps

media

12

1a) Afstand is +- 3cm as jy met `n leniaal meet

b) scale is 1: 200 km

= 3cm on map x 200 km

actual distance = 600 km

c) afstand is +- 8,4 cm as jy met `n leniaal meet

d) scale is 1: 200 km

= 8,4 cm on map x 200 km

= 1680 km for the actual distance

Multiple Choice

What is the formula for distance, time and speed?

/

Wat is die formule vir afstand, tyd en spoed ?

1

time = distance ÷ speed

tyd = afstand ÷ spoed

2

time = speed ÷ distance

tyd = sped ÷ afstand

3

speed = time ÷ distance

spoed = tyd ÷ afstand
