Formerly used in navigation, and now a tool used in surveying, a theodolite is used to measure what?
Theodolite Theodolite A theodolite is a precision optical instrument for measuring angles between designated visible points in the horizontal and vertical planes. The traditional use has been for land surveying, but they are also used extensively for building and infrastructure construction, and some specialized applications such as meteorology and rocket launching. It consists of a moveable telescope mounted so it can rotate around horizontal and vertical axes and provide angular readouts. These indicate the orientation of the telescope, and are used to relate the first point sighted through the telescope to subsequent sightings of other points from the same theodolite position.
Formerly Used Defense Sites Formerly Used Defense Sites Formerly Used Defense Sites (FUDS) are properties that were owned by, leased to, or otherwise possessed by the United States and under the jurisdiction of the United States Secretary of Defense. The term also refers to the U.S. military program created in 1986 for assessment and environmental restoration, if any, led by the U.S. Army Corps of Engineers. Of the potential 10,000 FUDS that have been used for military training, production, installation and testing of weapon systems the U.S. military has reviewed over 9,800 sites in the US and "its territories" for contamination by the Department
