WebJan 1, 1995 · Conventionally, tacheometry is the procedure by which horizontal distances and differences of elevation are determined using the optical properties of the telescope of the measuring instrument (transit, theodolite, level or tacheometer). The method has long been acknowledged as a simple and inexpensive tool for mapping areas of limited extent. WebPrinciple of Tacheometry. The basic principle of Tacheometry is based on the basic principle of an isosceles triangle. On any two sides equal triangle means an isosceles triangle, there is one property that is used in the Tacheometry. Ratio of the perpendicular to vertex on their base and their base is always constant in isoceles triangle.

WebJul 7, 2024 · A tachymeter or tacheometer is a type of theodolite used for rapid measurements and determines, electronically or electro-optically, the distance to target, and is highly automated in its operations. Such tachymeters are often used in surveying. Tachymetry or tacheometry is the process of measuring distance indirectly. Tacheometry is a system of rapid surveying, by which the horizontal and vertical positions of points on the earth's surface relative to one another are determined without using a chain or tape, or a separate levelling instrument. Instead of the pole formerly employed to mark a point, a staff similar to a level staff … See more A tachymeter or tacheometer is a type of theodolite used for rapid measurements and determines, electronically or electro-optically, the distance to target. The principles of action are similar to those of rangefinders See more Other forms of tacheometry in surveying include the use of stadia rods with theodolites or plane-table alidades. These use stadia marks on the instrument's reticle to measure the distance between two points on the stadia rod (the stadia interval). This is … See more Another device used in tacheometry is the subtense bar. This is a rigid rod, usually of a material insensitive to change in temperature such as See more
