The unmatched feature of Therion software among other software tools for cave surveying is straightforward creating of 3D presentation for WEB pages. One may export 3D model from Therion to 3D format .lox, open it in Therion's 3D viewer Loch and export data as VTK. ParaView software is able to open such data and export them in WebGL format.
Although link chains were later superseded by the steel ribbon tape (a form of tape measure), its legacy was a new statutory unit of length called the chain, equal to 22 yards (66 feet) of 100 links. [8] This unit still exists as a location identifier on British railways, as well as all across America in what is called the public land survey ...
Pacing is a reasonably easy and quick method of measuring distance in the field. [1] It is used to measure a distance and is often used with a sighting or a hand compass.Most commonly, pacing is split up into segments, such as chains, which are set measures of distance.
L is the length of the tape or length of the line measured. T m {\displaystyle T_{m}} is the observed temperature of the tape at the time of measurement; T s {\displaystyle T_{s}} is the standard temperature, when the tape is at the correct length, often 20 °C;
The rod, perch, or pole (sometimes also lug) is a surveyor's tool [1] and unit of length of various historical definitions. In British imperial and US customary units, it is defined as 16 + 1 ⁄ 2 feet, equal to exactly 1 ⁄ 320 of a mile, or 5 + 1 ⁄ 2 yards (a quarter of a surveyor's chain), and is exactly 5.0292 meters.
The prior land survey data for North America of 1927 (NAD27) had been based on the survey foot, and a new triangulation based on the metric system (NAD83) was not released until 1986. Since that time, the State Plane Coordinate Systems (SPCSs) established by the U.S. Geodetic Survey have been based in SI units in all states. But a few states ...

In the United States Public Land Survey System, a baseline is specifically the principal east-west line (i.e., a parallel) upon which all rectangular surveys in a defined area are based. The baseline meets its corresponding principal meridian (north-south line) at the point of origin, or initial point, for the land survey.
