This new distance unit is named as meridional part which is the increased length of the meridian on a Mercator chart measured from the equator to the parallel (latitude) and is expressed in minutes of the longitude scale.
equator as a unit, constitutes the number of meridional parts (M) corresponding to that latitude. Meridional parts, given in Table 6 for every minute of latitude from the equator to the pole, make it possible to construct a Mercator chart and to solve problems in Mercator sailing. These values are for the WGS ellipsoid of 1984. 307.
Calculation of the meridional parts used in the construction of Mercator charts and in Mercator sailing for each minute of latitude from the equator to the poles. Enter the latitude for which the meridional part is desired.
Table 6. Meridional Parts – In this table the meridio-nal parts used in the construction of Mercator charts and in Mercator sailing are tabulated to one decimal place for each minute of latitude from the equator to the poles. The table was computed using the formula: in which M is the number of meridional parts between the equator and the ...
Meridional Parts. This page allows calculation of the meridional parts used in the construction of Mercator charts and in Mercator sailing for each minute of latitude from the equator to the poles. Enter the latitude for which the meridional part is desired.
