A hemisphere is a half-sphere, for example, half the Earth: northern, southern, eastern, western hemisphere.
In a forum post related to a ESA satellite station in Argentina, I came across the phrase "having such an strategic and experienced partner on the South West hemisphere".
Now obviously, the South West hemisphere is not a hemisphere, but a half-hemisphere. Is there a word for a quarter-sphere, south as, in the geographical case, the north west, north east, south west, south east?
Maybe something like quadrasphere?
