When taking height, users measure either 66 or 120 feet from the tree; this is the reason for the multiple scales in the relascope. Users then look first at the top of the tree or at the highest point on the bole that they want to measure and record the number from the height dial inside the scope, then they look at the bottom of the tree to ...
Badda (Arabic: بطا, [1] Baṭṭā) [2] was a medieval settlement in the interior of the Somali Peninsula It is the oldest recorded urban settlement in the interior of what is now Somalia , being first mentioned in the Nuzhat al-mushtāq of al-Idrīsī in 1154.
It looks much like an everyday yardstick. With practice a Biltmore stick is considered to be exceptionally accurate, often within half an inch on diameters. Some foresters use the tool regularly, however, many prefer to use more accurate tools such as a diameter tape to measure diameter at breast height (DBH) and a clinometer to measure height ...
A height gauge is a measuring device used for determining the height of objects, and for marking of items to be worked on. [1] These measuring tools are used in metalworking or metrology to either set or measure vertical distances; [citation needed] the pointer is sharpened to allow it to act as a scriber and assist in marking out work pieces.

Calculation from this value will eventually give the height h, from the eye-line of the observer to the top of the object whose height is to be determined. Similarly as in step 2 of the illustration, a sighting is taken on the base of the object whose height is to be determined, and the reading on the horizontal scale, d', recorded.
Standardized measurements are essential to technological advancement, and early measurement tools have been found dating back to the dawn of human civilization. [1] Early Mesopotamian and Egyptian metrologists created a set of measurement standards based on body parts known as anthropic units. These ancient systems of measurements utilized ...
A direct-readout theodolite, manufactured in the Soviet Union in 1958 and used for topographic surveying. A theodolite (/ θ i ˈ ɒ d ə ˌ l aɪ t /) [1] is a precision optical instrument for measuring angles between designated visible points in the horizontal and vertical planes.
Lux meter for measuring illuminance, i.e. incident luminous flux per unit area; Luminance meter for measuring luminance, i.e. luminous flux per unit area and unit solid angle; Light meter, an instrument used to set photographic exposures. It can be either a lux meter (incident-light meter) or a luminance meter (reflected-light meter), and is ...
