What are the Meridional Parts?
The distance of a degree of longitude on the Planet spheroid is roughly the same as a degree of latitude equal to 60 nautical miles at the equator.
As it gets closer to the pole where all meridians converge at a single point, the distance
for a degree of longitude reduces while the distance for a degree of latitude stays nearly constant.
A common way of viewing the Earth spheroid is being used in the Mercator projection.
All the meridians are graphed on the map as parallel lines, making it necessary to increase the distance representing a degree of latitude (which is simply a constant on the spheroid of the Earth) in order to retain the aspect.
On a Mercator map measured from the equator to the parallel (latitude), this new distance unit is called the
meridional component, which is the increased length of the meridian, which is expressed in minutes of the longitude scale.
As the southern sections are longitude di longitude units of the same distance,
Mercator maps and Mercator navigation sails from the equator to the poles for any minute of latitude; it also measures direction and lengths.
The distance of a degree of longitude on the Earth's curved crust is roughly the same as that of a degree of latitude, but only at the equator. The distance is 60 nautical miles or so.
The gap reduces by a degree of longitude as it gets closer to either pole, north or south.
Those poles are where at a single point, all surface meridians cross.
The distance from the equator to the degree of latitude remains virtually constant.
Join the latitude of the desired southern section.
Latitudes can be entered as decimal degrees either by filling in the area of degrees or by entering the values of all fields as degrees and minutes. To measure only the southern
part, click on Calculate MP.
Fill out the same details for both the departure point and the destination point, both latitude, and longitude, for additional detail.
