Surveying in Modern Era with Total Station

Surveying is one of the most important and oldest practices carried out. It includes measuring various geographical areas above, on or below the surface and planning the action according to the survey results. The surveying in the past was done manually with the help of theodolite but in modern times, methods of surveying have changed dramatically due to advancements in technology. Surveying with total station is done with the help of quality engineering supplies.

A total station is opto-electronic instrument used for survey and archaeological purposes to make measurement. It is used by police, crime scene investigators, insurance companies, private accident re-constructionist. It is an integration of electronic distance meter (EDM), electronic theodolite, and software running on an external computer known as a data collector. Surveying with total station is used for mapping and contouring purposes.

The measurement of distance or a property can be done with the help of quality engineer supply materials such as wheels, measuring tapes and lasers. These supplies are user-friendly, fast and accurate. There are various types of supplies, apart from those mentioned above, such as callipers, micrometers, calculators, digital and electronic levels and much more.

The new era of surveying with total station and much development of engineering products have increased productivity. Primarily, the accuracy has improved much. The coordinate points measured by the total station are much accurate as they make use of supplies such as GPS devices. The GPS includes unseen points in the survey which help in correct survey. Other factors which led to increase in productivity are efficiency and functionality. Many total stations are robotic such as Leica Viva TS15 which is used by Jurovich Surveying. The remote controller streams the view of total station to a surveyor at a remote point, who takes measurements and can change the target area without needing to return to the total station.

Other equipments from engineering supplies are used such as high-resolution cameras to capture high-quality image from the surveying site, thus, eliminates the need for costly revisits, and produces high-resolution images of site conditions. One of the major improvements in the surveying with total station is functions such as electronic documentation and sketching. It reduces the need for paper field notes and also is secured.

Finally, the data collected from the survey with total station can be downloaded to any computer for purposes of distribution, archiving, generating reports and much more. The data can also be used with other mapping softwares for further applications.  

The manual theodolite has been replaced with modern total station as the surveyor’s essential field tool and with so many supplies, the task of archaeologists has become much easier and results can be found accurately and speedily. So, utilize surveying with total station features in order to attain best results!

 

Theodolites – Precise Angle Measuring Instrument

How fascinating geometry was when we were in school and used protractor to measure the angle between two lines! It was so simple on a sheet of paper. In real world calculating precise angles is very important. Tools like theodolites are a tool designed to basically measure the verticals and horizontal planes precisely. With the increasing use of technology in fields such as construction of buildings and roads, mining, meteorology, rocket launching technology and much more, accurate measurement of angles is a must. 

Designing of theodolites comprise of telescope mounted between horizontal and verticalaxes on a pivot. Levelling of this telescope is done using spirit level. Now-a-days the telescopes are movable with axes perpendicular to each other. The angle of each of these axes can be measured accurately, when the telescope is kept pointing in line of sight of the object. Sight of the object is measured precisely because of crosshairs in the telescopes. 

Theodolites are mainly used in surveying, manufacturing of instruments and engineering industry. As the scope of its usage has widened, they are now being used for special purpose such as designing layouts for roads, bridges, swimming pools, golf courses etc. When it comes to theodolite survey, manufacturers have to keep in mind while designing the instrument, the accuracy with which it will be measuring the angles. Accuracy ranges from 5 sec to 0.1 sec.

Functionally theodolites are mainly of two types, Transit and Non- Transit. Transit theodolite has provision that the telescope can be inverted in the vertical plane, whereas in non transit theodolite the rotation in the same plane is allowed only up to 90 degrees (restricted to a semi-circle).

There are some drawbacks or may be limitations while using these equipments. While calculating the angles of the axes, the operator of the instrument should be well versed with Trigonometry. It is not possible for difficult terrain, but appropriate for small size plots. By use of digital theodolites, these problems can be overcome. Theodolite manufacturers are more focusing on long distance terrain measurement. Design of these instruments is such that even a layperson can use. Manufactures has also come up with Electronic theodolites to overcome the other problem which is operator should know the trigonometry, as these instruments automatically calculate the angles.

With increasing advent of technology, many things are incorporated in these new theodolites by Tiger Supplies. Since it is a low differentiated category, the manufacturers are now focusing on longer battery life, water proofs for different seasons and dust proofs for difficult terrain.
