  • What are External focusing telescope

    Binoculars in which focusing is achieved either by external movement of the objective glass or the eyepiece are known as external focusing binoculars. In an external focusing telescope, the body consists of two tubes with the objective and the eyepiece mounted on the ends. One tube is made to slide axially inside the other by…

  • What is Telescope

    A telescope is an optical instrument for magnifying and viewing images of distant objects. The telescope of a leveling instrument is a metal tube with an eyepiece at one end and a mirror at the other end. Telescopes, which are mounted in surfaces, are generally of two types. External focusing telescopeInternal focusing telescopeExternal focusing telescopes…

  • What are major parts of Levelling instrument

    The surface presents a horizontal line of sight. The surface consists of the following main parts. A telescope to provide line of sightA level tube to make the line of sight horizontalA leveling head to bring the bubble into the center of the runA tripod to support the device.

  • What is Purpose of levelling

    To find the elevations of given points with respect to a given or assumed datum (a datum is an arbitrarily assumed surface level to which elevations are referenced).Establishing points at a given elevation with respect to a given or assumed datum.The following are the instruments used in leveling: A surfaceA leveling staffA measuring tape

  • What is Digital planimeter

    A planimeter is an instrument used to measure the area of ​​irregular shapes. The original version consisted of tracing the boundaries with the arm of the planimeter and then converting the obtained reading to the area of ​​the figure using a specific formula. Here, the possibility of error is very high and the procedure is…

  • What is Electronic digital theodolite

    It works like an ordinary transit theodolite, except that it is more accurate, error-free and easier to operate. An electronic compensation is provided, which simplifies the leveling process and improves accuracy by compensating for poor adjustments. A laser plummet is provided for accurate centering. Electronic display of all readings is automatically available. It works on…

  • What is Microptic theodolite

    It is a reliable, convenient, highly accurate and easy-to-use instrument used for most surveying tasks including engineering and mining applications. It is equipped with magnetically damped vertical circle compensation for fast and accurate zenith angle compensation. The provided optical plummet makes it easy to center the instrument on the survey point with the help of…

  • What is Digital level

    Digital Level and Bar Code Applicator. Digital, electronic image processing to determine heights and distances in this surface, with automatic recording of data for later transfer to a computer. A digital level is an automatic level (pendulum compensator) capable of performing normal optical leveling with a rod graduated in feet or meters. When used in…

  • Auto level

    Automatic levels are extremely popular in modern day surveying work and are very easy to set up and can be used with any amount of accuracy.They can be simply mounted on a tripod and can be set up and the circular bubble brought to the centre easily even on an angled and uneven surface. The…

  • What is (GPS) Global positioning system

    GPS is a satellite navigation system designed to provide instantaneous position, speed and time information anywhere in the world at any time and in any weather.Present usage of GPS for positioning includes personal navigation (hiking, boating, hunting, driving directions, etc.), aircraft navigation, offshore survey and vessel navigation, fleet tracking, dredging, machine control, civil engineering, land…
