What does a Geodimeter do?
What is Distomat instrument?
The Distomat is a very small, compact electronic distance measurement device, particularly useful in construction and engineering works. The Distomat measures distances smaller than 500 meters by simply pointing the instrument to a reflector and reading the result.Aug 23, 2019
Who invented Geodimeter?
Erik Bergstrand, the inventor of the Geodimeter, was brought up in an astronomical observatory as his father was professor of astronomy in Uppsala, Sweden. Erik studied physics in the 1920's and was a keen builder of radio receivers in the early days of broadcasting.Jun 19, 2008
What is a total station used for?
A Total Station is a modern surveying instrument that integrates an electronic theodolite with an electronic distance meter. A theodolite uses a movable telescope to measure angles in both the horizontal and vertical planes.
How do you use a Graphometer?
To use the graphometer, the fixed sights on the straight line of the semicircle were used to aim at a landmark and the movable sighting rule was used to aim at the second point. The angle between the two points could then be read off the scale.Dec 7, 2020
How are Clinometers used?
A clinometer is a tool that is used to measure the angle of elevation, or angle from the ground, in a right - angled triangle. You can use a clinometer to measure the height of tall things that you can't possibly reach to the top of, flag poles, buildings, trees.
What is electronic surveying?
1. Is one in which a computer plays a major role in both the delivery of a survey to potential respondents and the collection of survey data from actual respondents. Learn more in: Surveys as a Complementary Method for Web Log Analysis.
For what purpose is Distomat used ans?
DISTOMAT DI 1000
It is a very small, compact EDM, particularly useful in building construction and other Civil Engineering works, where distance measurements are less than 500 m. It is an EDM that makes the meaning tape redundant.Dec 5, 2016
What is the range of Geodimeter?
Explanation: Geodimeter is a classification of EDM based on carrier wave. This instrument uses visible light as its source and possesses a range of 25 km, having accuracy up to 2-3km.
Who invented total station?
The total station was first introduced to surveyors under a variety of names, including electronic tacheometer and EDM theodolite. Initially, Total Station was a proper noun introduced by Hewlett-Packard (HP) to promote its Model 3810A around 1975.Oct 24, 2016
What is total station and how it works?
A theodolite can be mechanical or electronic. A total station can measure angles and distances electronically and process trigonometrically to give us, at a minimum, position coordinates in space. ... The horizontal distance, height difference and bearings are calculated automatically.
How does a geodimeter measure distance?
- Geodimeters, like other light-based electronic distance measuring instruments, worked by sending a light signal of known wavelength to a reflector. The wavelength of the returning signal was compared to the outgoing one, and the difference (called the "phase shift") was measured.
What is the geodimeter 120 (1978)?
- The Geodimeter 120 (1978) was referred to as a semi-total station and, for the first time, interfaced with the Geodat data collector. It also provided tracking, or repeated measurements.
When was the first geodimeter invented?
- Photos courtesy of Charlie Glover. Improvements in Geodimeters since their inception in 1953 increased the utility of these instruments for measuring distances in a range of conditions.
How much does a geodimeter weigh?How much does a geodimeter weigh?
In fact, however, the early Geodimeter weighed over 200 lbs-the measuring unit weighed some 108 pounds and the optical unit weighed some 113 pounds-and it required a generator to supply power. It had a useful range of 30-35 km. Of the ten Model 1 Geodimeters produced in 1953, five were purchased by geodetic agencies of the United States government.
What is the geodimeter system 400?What is the geodimeter system 400?
According to the manufacturer "The Geodimeter System 400 is the first surveying system where hardware and software have been integrated in an intelligent and powerful unit." 1 The Geodimeter System 400 was launched in 1986 as a modular system.

What is the difference between a 420 and 424 geodimeter?What is the difference between a 420 and 424 geodimeter?
The two Geodimeters shown here are a conventional one (the 420) and an alphanumerical one (the 424). Before the Geodimeter System 400, total stations like the Kern E1 could already measure vertical and horizontal angles, and distances, but at the most they were only able to reduce slope distances to vertical and horizontal distances.
