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.

WebJan 1, 2001 · This means that in both cases, “semi-electronic tacheometry” gives accuracy figures much better (two to three times) than conventional optical stadia techniques. These high accuracy figures are believed to be attributed partially to repeated measurements and partially to the improved design of modern electronic theodolites used in the test.
