Splet01. jan. 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.

Introduction This method of survey consists of using either a level, theodolite or specially constructed tacheometer to make cross hair intercept readings on a levelling staff. As the angle subtended by the crosshairs is known, the distance can be calculated. Definition Tacheometry is an optical solution to the measurement of distance. The word …

A theodolite is used to measure the angle between indicators on the two ends of the subtense bar. The distance from the telescope to the subtense bar is the height of an isosceles triangleformed with the theodolite at the upper vertex and the subtense bar length at its base, determined by trigonometry.

The technique uses a principle known as the stadia method, which is based on the differences in scale between two images. the iceman teljes film magyarulSpletIt is one of the fastest methods of surveying. The accuracy of tacheometric surveying in uneven or difficult terrain is quite satisfactory. Does not require any tedious jobs with tapes and chains. Cost efficient with relative to time.
