Brass

Brass is an alloy of copper and zinc, in proportions which can be varied to achieve different colours and mechanical, electrical, acoustic and chemical properties, but copper typically has the larger proportion, generally 66% copper and 34% zinc.

Geodesy

Geodesy or geodetics is the science of measuring and representing the geometry, gravity, and spatial orientation of the Earth in temporally varying 3D.

Navigation is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another.

See Étienne Lenoir (instrument maker) and Navigation

Platinum

Platinum is a chemical element; it has symbol Pt and atomic number 78.

See Étienne Lenoir (instrument maker) and Platinum

Reflecting instrument

Reflecting instruments are those that use mirrors to enhance their ability to make measurements.

See Étienne Lenoir (instrument maker) and Reflecting instrument

Repeating circle

Developed from the reflecting circle, the repeating circle is an instrument for geodetic surveying, invented by Etienne Lenoir in 1784, while an assistant of Jean-Charles de Borda, who later improved the instrument.

See Étienne Lenoir (instrument maker) and Repeating circle

Ruler

A ruler, sometimes called a rule, scale or a line gauge, is an instrument used to make length measurements, whereby a user estimates a length by reading from a series of markings called "rules" along an edge of the device.

See Étienne Lenoir (instrument maker) and Ruler

Surveying

Surveying or land surveying is the technique, profession, art, and science of determining the terrestrial two-dimensional or three-dimensional positions of points and the distances and angles between them.
