Rhumb Line

In navigation, a rhumb line (or loxodrome) is a line crossing all meridians of longitude at the same angle, i.e. a path derived from a defined initial bearing. That is, upon taking an initial bearing, one proceeds along the same bearing, without changing the direction as measured relative to true north.

Famous quotes containing the word line:

    A line will take us hours maybe;
    Yet if it does not seem a moment’s thought,
    Our stitching and unstitching has been naught.
    William Butler Yeats (1865–1939)
