Digital Level Surveying we civil engineers

Sep 02, 2018· Digital levels use electronic image processing to evaluate the special bar-coded staff reading, This bar-coded pattern is converted into elevation and distance values using a digital image matching procedure within the instrument. ADVANTAGES OF DIGITAL LEVEL Correction of collimation error: Can be reliably determined and saved using the four integrated Check and Adjust procedures or

Levelling in Engineering Survey Types, Methods, Procedures

Levelling is the most widely used method of obtaining the elevations of ground points relative to a reference datum and is usually carried out as a separate procedure to those used in fixing planimetric position. The basic concept of leveling involves the measurement of vertical distance relative to a horizontal line of sight. Digital Level

Methods of Levelling Online CivilForum

Dec 16, 2020· This method is also useful only for exploratory survey. Direct Levelling. It is common form of levelling in all engineering projects. In this method horizontal sight is taken on a graduated staff and the difference in the elevation of line of sight and ground at which staff is held are found.

Theodolites How Does a Theodolite Work Johnson Level

Digital theodolites are convenient because the digital readouts take the place of traditional graduated circles and this creates more accurate readings. Parts of a Theodolite. Like other leveling instruments, a theodolite consists of a telescope mounted on a base. The telescope has a sight on the top of it that is used to align the target.

3 LEVELLING & SURVEYING

Levelling and surveying methods are also used for measurements of river channel and lake configurations. Often, less accurate methods can be used for this work than for water-level recording stations, although the techniques are common. 3.2 Definitions Differential levelling is the term applied to any method of measuring directly with a graduated
