Grade 8

Mapwork

Module 13

Designation of topographic maps

Topographic maps of the RSA are drawn according to degree square .

Each degree square is indicated by means of a number that consists of four figures. These figures are assembled from the values of the latitudinal and longitudinal degrees shown at the northwesterly corner of the map.

The shaded square is the map sheet with which we are working at present.

What information does it provide?

2228 CD represents the following:

22 = 22º latitudinal line (South)

28 = 28º longitudinal line (East)

C = square divided into four squares that represent 30’ of a degree and are always named in the sequence AB.

CD

B = the larger square C is also divided into four squares, each representing 15’ of a degree. The sequence in which they are named also is AB.

CD

Each squared degree is therefore spread out over sixteen 1:50 000 topographic map sheets.

ACTIVITY 1:

[LO 1.2]

1. Indicate the location of the following 1:50 000 map sheets by making use of a representation.

2822 DA

3528 BC

2. Which map sheet lies immediately to the North of 2822 DA?

3. Which map sheet lies immediately to the East of 3528 BC?

4. Which map sheet west of 2822 DA?

5. Which map sheet lies South of 3528 BC?

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
