Basic GIS Coordinates - Chapter 5 (end)

Một số khẳng định rằng Khảo sát hệ thống đất công cộng (PLSS) là một hệ thống phối hợp. Những người khác mạnh mẽ duy trì rằng nó chắc chắn là không. Nó đủ để nói rằng hơn 200 năm, nó đã được, và tiếp tục được, một hệ thống phân chia đất và mô tả tài sản ở hầu hết các của Hoa Kỳ ban đầu được thành lập bởi Đạo luật đất đai của Pháp lệnh ngày 20 tháng năm 1785. Hệ thống này đã được từng bước cải thiện thông qua sự đổi mới thực tế và. | chapter five The Rectangular System Public lands Some assert that the Public Land Survey System PLSS is a coordinate system. Others strongly maintain that it certainly is not. Suffice it to say that for more than 200 years it has been and continues to be a system to divide land and describe property across most of the U.S. It was originally established by the Land Ordinance Act of May 20 1785. The system has been incrementally improved through practical innovation and government regulation. The Department of the Treasury had jurisdiction over the PLSS from its beginnings until 1812. That was a sensible arrangement since the government was poor in cash and rich in land. The land came to be known as the public domain meaning land that was once or is even now owned by the federal government of the U.S. What was needed was a practical reliable and unambiguous method of disposal. The fledgling federal government had to pay its soldiers often with land instead of cash. It needed to disperse the population on the land to realize that land s potential. Put simply the government had to raise money. From the very beginning of the PLSS it has always been the policy of the federal government that land in the public domain must be surveyed before it is sold to others that is before it is patented. Therefore the U.S. embarked on the most extensive surveying project ever undertaken. The work began in Ohio in autumn 1785. On April 25 1812 Congress created the General Land Office GLO to survey and administer the PLSS. Under the GLO the work was done under a contract system. The contractors were Deputy Surveyors who worked for Surveyors General across the country. The surveying was not actually done by government employees until 1910. Later in 1946 the Bureau of Land Management BLM was created in the Department of the Interior. It has been in charge of the system since. The PLSS was and is an eminently practical attempt to cover a large portion of the curved surface of the Earth .
