The General Land Office (1812 - 1946) was an independent agency charged with the administration and sale of public lands of the western territories of the United States under the Preemption Act of 1841 and the Homestead Act of 1862. During a time of frenetic energy and rapid westward expansion, the Land Office oversaw the surveying, platting, mapping and eventually the sale of much of the Western United States and Florida. The structural layout of the western United States that we see today, and many of their district and county divisions, are direct result of the early surveying work of the General Land Office. More importantly, as a branch of the Federal Government in Washington D.C. and the only agency able to legally sell and administer public lands in the western territories of the United States, the General Land Office played a pivotal role in consolidating power away from the original states and into the hands of the centralized federal government. The General Land Office was absorbed into the Department of Interior in 1849 and in 1946 merged with the United States Grazing Service to become the Bureau of Land Management. Today the Bureau of Land Management administers the roughly 246 million acres of public land remaining under federal ownership. More by this mapmaker...

The British Admiralty Office (1795 - Present) or the United Kingdom Hydrographic Office refers to the Branch of the English government that is responsible for the command of the British Navy. In 1795 King George III created the United Kingdom Hydrographic Office, known in short as the U.K.H.O., to provide top notch nautical charts to the vast Royal Navy. Prior the founding of the Admiralty the surveying and creation of nautical charts was primarily a commercial venture wherein the cartographer himself, more of than not, actually financed the printing of his own material. The great navigator Cook himself is known to have scrambled for funds to publish his own seminal charts - the most important and advanced of the period. The system of privately funded nautical mapping and publishing left vast portions of the world uncharted and many excellent charts unpublished. King George III, responding significant loss in trade revenue related to shipwrecks and delay due to poor charts, recognized the need for an institutionalized government sponsored cartographic agency - the Admiralty. The first head of the Admiralty, a position known as Hydrographer, was the important cartographer Alexander Dalrymple. Dalrymple started by organizing and cataloging obtainable charts before initiating the laborious process of updating them and filling in the blanks. The first official Admiralty Chart appeared in 1800 and detailed Quiberon Bay in Brittany. By 1808 the position of Hydrographer fell to Captain Thomas Hurd. Hurd advocated the sale of Admiralty charts to the general public and, by the time he retired in 1829, had issued and published some 736 charts. Stewardship of the organization then passed to Rear Admiral Sir Francis Beaufort. It was under Beaufort's administration that the Admiralty truly developed as a "chart making" as opposed to a "chart cataloging" institution. Beaufort held his post from 1829 to 1854. In his 25 years at the Admiralty Beaufort created nearly 1500 new charts and sponsored countless surveying and scientific expeditions - including the 1831 to 1836 voyage of the H.M.S. Beagle. By 1855 the Admiralty's chart catalog listed some 1,981 charts. Learn More...
