A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

DIE KAARTNAAM VAN TOPOGRAFIESE KAARTE

  1. Die kaartnaam van topografiese kaarte

Die RSA topografiese kaarte word geteken aan die hand van graadvierkante.

Elke graadvierkant word aangedui deur ’n getal wat uit vier syfers bestaan. Hierdie syfers word saamgestel uit die waardes van die breedte- en lengtegrade by die kaart se noordwestelike hoek.

  • Die geskakeerde blok is die kaartvel waarmee tans gewerk word.
  • Wat sê dit alles?
  • 2228 CD verteenwoordig die volgende:
  • 22 = 22º breedtelyn (suid)
  • 28 = 28º lengtelyn (oos)
  • C = vierkant word in vier blokke verdeel wat 30' van ’n graad voorstel en word altyd in die volgorde AB benoem. CD
  • B = die groot vierkant C word weer in vier blokke verdeel wat 15' van ’n graad voorstel. Dit word ook in die AB volgorde benoem. CD

Elke graadvierkant word dus in sestien 1:50 000 topografiese velle verdeel.

AKTIWITEIT 1

2. Watter kaartvel lê direk noord van 2822 DA?

3. Watter kaartvel lê direk oos van 3528 BC? .

4. Watter kaartvel lê wes van 2822 DA? .

5. Watter kaartvel lê suid van 3528 BC?

Assesseringstandaarde(ASe)
 
Dit is duidelik wanneer die leerder:
1.1 ‘n verskeidenheid geografiese en omgewingsbronne identifiseer en selekteer wat relevant tot die navorsing is;1.2 inligting vanaf kaarte en atlasse, asook grafiese en statistiese bronne, interpreteer;1.3 afstandberekening doen op kaarte en dit vergelyk met werklike afstand;1.4 fisiese en mensgemaakte eienskappe op lugfoto’s en kaarte identifiseer.
