  2. Stadiametric rangefinding - Wikipedia

    en.wikipedia.org/wiki/Stadiametric_rangefinding

    For telescopic angles, the approximations of ⁡ = ⁡ = greatly simplify the trigonometry, enabling one to scale objects measured in milliradians through a telescope by a factor of 1000 for distance or height. An object 5 meters high, for example, will cover 1 mrad at 5000 meters, or 5 mrad at 1000 meters, or 25 mrad at 200 meters.

  3. Surveyor's wheel - Wikipedia

    en.wikipedia.org/wiki/Surveyor's_wheel

    The trundle wheel is composed of a wheel, a handle which is attached to the axle allowing the trundle wheel to be held easily, and a clicking device which is triggered once per revolution of the wheel. Trundle wheels are not as accurate as other methods of measuring distance but are a good way to get a rough estimation of a fairly long distance ...

  4. Level staff - Wikipedia

    The tenths of a foot point is indicated by the top of the long mark with the upward sloped end. The point halfway between tenths of a foot marks is indicated by the bottom of a medium length black mark with a downward sloped end. Each mark or space is approximately 3mm, yielding roughly the same accuracy as the metric rod.

  5. Surveying - Wikipedia

    en.wikipedia.org/wiki/Surveying

    Perambulators, or measuring wheels, were used to measure longer distances but not to a high level of accuracy. Tacheometry is the science of measuring distances by measuring the angle between two ends of an object with a known size. It was sometimes used before to the invention of EDM where rough ground made chain measurement impractical.

    Although there are more than 100 species of lemurs, the ring-tailed lemur is arguably the most well-known thanks to King Julien in the hit children’s film Madagascar. His need to “move it ...

  7. Brannock Device - Wikipedia

    en.wikipedia.org/wiki/Brannock_Device

    Brannock spent two years developing a simple means of measuring the length, width, and arch length of the human foot. He eventually improved on the wooden RITZ Stick, the industry standard of the day, [ 2 ] patenting his first prototype in 1925 [ 3 ] and an improved version in 1927. [ 1 ]
