The site was important for astronomical work (which of course had maritime applications), and was where the Prime Meridian (the basis of longitude) was established in 1851, and agreed upon by an international conference in 1884. Additionally, until 1954, Greenwich Meantime (GMT), which is now known as "Universal Time", was calculated based on observations from the Royal Observatory, Greenwich.

Product Description:
Longitude, identified by the Greek letter lambda (?), is the geographic coordinate most commonly used in cartography and global navigation for east-west measurement. The line of longitude (meridian) that passes through the Royal Observatory, Greenwich, in England, establishes the meaning of zero degrees of longitude, or the prime meridian. Any other longitude is identified by the east-west angle, referenced to the center of the Earth as vertex, between the intersections with the equator of the meridian through the location in question and the prime meridian. A location's position along a meridian is given by its latitude, which is identified by the north-south angle between the local vertical and the plane of the equator.
