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 about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct

is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
