Nautical time refers to a system of timekeeping that is used primarily in maritime settings. It is closely related to the concept of nautical almanacs, navigational calculations, and the operation of ships at sea. There are a few key aspects of nautical time: 1. **Time Zones**: Nautical time can reflect the use of time zones based on Greenwich Mean Time (GMT) or Universal Coordinated Time (UTC).
A Principal Meridian is a fundamental reference line used in the Public Land Survey System (PLSS) in the United States. The PLSS is a method for surveying and categorizing land to facilitate property ownership and land management. The Principal Meridian serves as a starting point for defining the township and range system used in the PLSS. Each Principal Meridian is associated with a specific geographic area and is typically accompanied by a Baseline, which runs perpendicular to it.
Principal meridians are the reference lines used in the Public Land Survey System (PLSS) for surveying and mapping land in the United States. In Alaska, the principal meridian is the **Copper River Meridien**. This meridian serves as the basis for surveying land in the areas that were established under the PLSS in Alaska. Additionally, it's worth noting that Alaska has a unique surveying system due to its vast size and diverse geography, which includes several other linear systems and regional adjustments.
The Second Principal Meridian is one of the principal meridians used in the Public Land Survey System (PLSS) in the United States. Principal meridians are the key reference lines used in the surveying and division of land. Each meridian serves as a baseline for establishing townships and ranges, which help in the systematic parceling of land primarily in the western United States. The Second Principal Meridian, established in 1815, runs through a specific location in the U.S.
The Sixth Principal Meridian is a north-south line designated for surveying purposes in the United States. It serves as a reference point for the Public Land Survey System (PLSS), which is used to systematically divide and describe land in certain areas of the U.S. The Sixth Principal Meridian runs primarily through the states of Nebraska, Kansas, and a portion of Colorado. It was established in the mid-19th century and is significant in the context of land measurement and ownership in the central United States.
The Third Principal Meridian is a north-south line of longitude that serves as a reference point for land surveying in the United States, specifically in the region west of the Ohio River. Established by the U.S. government in the early 19th century, it is one of several principal meridians used in the Public Land Survey System (PLSS). The Third Principal Meridian runs through an area that includes parts of the states of Illinois, Missouri, and Wisconsin.
The Treaty of Tordesillas, signed on June 7, 1494, was an agreement between Portugal and Spain aimed at resolving disputes over newly discovered lands in the Americas and the exploration of the world. It was facilitated by the Pope, who sought to prevent conflict between the two major maritime powers of the era. The treaty established a meridian 370 leagues west of the Cape Verde Islands, officially dividing the newly discovered lands outside Europe between Spain and Portugal.
The Treaty of Zaragoza, signed on April 22, 1529, was an agreement between Spain and Portugal that established a maritime boundary between the two nations in the Spice Islands, also known as the Moluccas. This treaty was a follow-up to the Treaty of Tordesillas, which had previously divided the newly discovered lands outside Europe between Spain and Portugal.
Washington Meridians is a term that can refer to two different concepts in the context of geography and surveying, but it is primarily associated with the geographic coordinate system used in mapping and surveying in the United States, especially in relation to the land management practices of the General Land Office (GLO). 1. **Geographic Meridians**: In general geography, meridians are the lines of longitude that run from the North Pole to the South Pole.
