The International Date Line zigzags around the 180th Meridian. The 180th meridian or antimeridian [1] is the meridian 180° both east and west of the prime meridian in a geographical coordinate system. The longitude at this line can be given as either east or west. On Earth, the prime and 180th meridians form a great circle that divides the ...
The International Date Line (IDL) is the line extending between the South and North Poles that is the boundary between one calendar day and the next. It passes through the Pacific Ocean , roughly following the 180.0° line of longitude and deviating to pass around some territories and island groups.
A prime meridian is an arbitrarily chosen meridian (a line of longitude) in a geographic coordinate system at which longitude is defined to be 0°. Together, a prime meridian and its anti-meridian (the 180th meridian in a 360°-system) form a great circle.
In geography and geodesy, a meridian is the locus connecting points of equal longitude, which is the angle (in degrees or other units) east or west of a given prime meridian (currently, the IERS Reference Meridian). [1] In other words, it is a coordinate line for longitudes, a line of longitude.
Figure 1. This BLM map depicts the principal meridians and baselines used for surveying states (colored) in the PLSS.. The following are the principal and guide meridians and base lines of the United States, with the year established and a brief summary of what areas' land surveys are based on each.
The United States and Kiribati have most of their territory east of the 180th meridian, in the Western Hemisphere, so they are considered to belong to the westernmost countries with their territory stretching as far to the west as beyond the 180th meridian into the Eastern Hemisphere. Conversely, Russia, New Zealand, and Fiji have most of their ...
Since early September, they had logged nearly 12,000 miles aboard the Offshore Surveyor, crisscrossing the equator near the 180th meridian. Now a few days past Thanksgiving, the time had come to ...
The 180th meridian (the meridian at 180° both east and west of the Prime Meridian) is opposite the IERS Reference Meridian and forms a great circle with it dividing the earth into Western Hemisphere and Eastern Hemisphere. Universal Time is notionally based on the prime meridian. [6]
