An astronomical parallel is a line connecting points having the same
astronomical latitude. A geodetic parallel is a line connecting points of
equal geodetic latitude. Geodetic and sometimes astronomical parallels are
also called geographic parallels. Geodetic parallels are shown on charts. A
standard parallel is one along which the scale of a chart is as stated. A
fictitious, grid, transverse, incerse, or oblique parallel is parallel to a
fictitious, grid, transverse, inverse, or oblique equator, respectively. A
magnetic parallel is a line connecting points of equal magnetic dip. [[/a>|/a>
