Ellicott's career as a surveyor "began in 1784 with his appointment as one of the commissioners for Virginia to clarify the boundaries between that state and Pennsylvania.He was commissioned with David Rittenhouse and Andrew Porter to define the western boundary of Pennsylvania, and in 1787 he completed a survey of the state's northern boundary. In 1789 Ellicott moved his family to Philadelphia and was employed by the federal government to survey the Presqu' Isle triangle, the tract north of the forty-second parallel and south of Lake Erie, a project that occupied him into 1791. In early 1796 President Washington commissioned him to undertake the survey of the boundary between the United States and the Spanish territory of Florida in accordance with a treaty with Spain. Ellicott kept a detailed account of all that came to his notice and obstruction he encountered from the Spanish. After completing the survey in the spring of 1800 he submitted his report to the State Department. Because President John Adams withheld it from the Senate, however, no appropriation was made for Ellicott's compensation, which left him in serious financial difficulties. After publication of his report in Philadelphia in 1803, he rose to considerable prominence in the world of science" (Silvio A. Bedini for ADNB).
