Kontoerlyne
Kontoerlyne – lyne op ‘n kaart wat op dieselfde hoogte bo seevlak is
Kontoerinterval – die verskil tussen enige twee kontoere
Sagte hellings – stukke grond waar die bopunt effens hoër as die omringende grond is
Steilheid – die vlak waarteen ‘n helling van laag na hoog strek
Gradiënt – ‘n meting om te beskryf hoe steil ‘n lyn of helling van ‘n heuwel of berg is
Wig – iets wat soos ‘n driehoek gevorm is
Uitloper – ‘n berg of heuwel wat aan die een kant van ‘n berg of bergstreeks uitsteek
Kontoerlyne op ‘n kaart
 Seevlak is 0 meter
 Hoogtes word in spasies al langs die kontoerlyne geskryf (in meter)
Kontoerpatrone
 Patroon wat koentoerlyne op kaart skep stel vorm van die grond op grondvlak voor

Steil helling Sagte helling
Koentoere naby mekaar Kontoere wyd uitmekaar uit

 Steilheid van ‘n helling word die gradiënt genoem
Riviervalleie en uitlopers
 Riviere vloei in valleie
 Waar twee riviere langs mekaar vloei is daar altyd ‘n wig heuwelagtige grond tussen hulle,

 Jy kan net die boonste eienskappe van dinge sien in ‘n lugfoto




Skuinsfoto- Sien net kante van geboue en lug in die agtergrond Vertikale lugfoto- Net boonste dele van eienskappe soos geboue word gesien




Inligting oor ortofotokaarte
‘n Ortofotokaart het die volgende eienskappe:
 Dit is ‘n vertikale lugfoto
 Altyd dieselfde skaal – 1 : 10 000 (1cm op die kaart is gelyk aan 10 000cm op die grond)
 Name van sekere terreinbakens soos strate, geboue en riviere word aangedui


Hoe hoogte op ortofotokaarte aangetoon word
Die ortofotokaart toon die hoogte van die grond deur kontoerlyne, kolhoogtes en trigonometriese
bakens.
