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.
