What is a Detail Survey? What is a Set-Out Survey? Assurance of pole tilt from a height or pointing on the ground, as well as reviewing a vertical line of a structure can be accurately done with a single face of the eyeglass, as long as it describes a completely vertical flat when turning it. This type of work requires a levelled second-hand total station to reduce the influence of vertical axis tilting.
When plotting a construction floor plan, point position and height are determined by measuring angles and distances. The instrument is placed on a point referred to a local coordinate system. For orientation purposes, a second point that is easy to distinguish is chosen after visaing it with the horizontal circle set to zero. To align a construction, it is useful to extrapolate the sides beyond the limits of the excavation, to determine the profiles of the limits on which stakes are placed.
During the construction process, ropes or cables can be tied to these reference points to indicate the wall positioning. ATR recognition is achieved quickly and easily. The most common application of this feature is the accurate controlling construction machinery guide.
TCR second-hand total stations of Leica Geosystems have a laser distance meter that does not require a reflector which is useful when you want to measure borders, place pipelines or in measurements along ravines or bars. Learn more about our used total stations and need some advice to choose which model is best for your tasks and projects, you can contact our sales dealers.
Professionals are then all working from the same drawing, reducing mistakes and discrepancies in the overall process. Whereas reporting traditionally could take hours, this technology is allowing companies to pull together as-built reports in just 15 minutes, again increasing overall workflow productivity. As more construction and surveying professionals have begun to recognise the value that robotic total stations have on productivity, they have become commonplace on sites.
Featuring a robotic total station, the equipment includes a scanner to allow construction professionals to scan and verify in addition to carrying out traditional robotic total station functions. Operating as a fully functional robotic total station and a high-speed, high-quality laser scanner means that, with a few clicks and few minutes of time, the GTL can produce a complete, degree, locally registered point cloud of an area.
As a result, the time taken for data capture and processing is sped up, saving a significant amount of time. There are not only short-term, but long-term time savings too. Using the GTL along with Verity software, it is easy to identify potential issues long before errors incur onsite costs.
For construction professionals this is extremely beneficial, as finding out something may have been installed incorrectly early in the construction process eliminates the extra costs of time and resources.
This can also avoid any negative reputational impacts that mistakes and additional work may bring. Without the GTL, scanning and analysing data can take days. However, with the technology, the process can be done in a matter of hours. An engineer can go out to the field in the morning to scan the latest installed elements, analyse the scan data and then be back on site before lunch with a list of changes that may have been identified.
In the past, this was not possible because of the time taken to complete the scanning and analysing process. The practicality of having just one instrument should also not be underestimated.
Usually, to register scan data, engineers would require a robotic or manual total station to coordinate scan targets, with these then scanned with the laser scanner then identified within a processing software package to register the point cloud. However, with a combined unit such as the GTL, engineers no longer need to set up two different instruments in the same location.
Available in 1, 3, and 5 second angle accuracies, you can select the instrument that best fits your requirements. Features Include:. There are many other facilities available, the total station can be used for the following purposes. Data Collection Option. The two options that are available are.
Detail Survey. Given two points whose coordinates are known, a total station can be used to get the coordinates of various other points based upon those two co-ordinates. Care should be taken that the new points survey are carefully coded. The Map of the area can be obtained after downloading and processing. It is similar to any type of EDM Traverse. Definition of Traverse: —. Traverse is the method of control survey in providing horizontal and vertical controls along a pre-defined route by means of establishing a series of connected lines joining the traverse stations.
Figure 4: Closed Circuit Traverse. Figure 5: Azimuth and Grid Bearing. The process of finding the height of objects without actually going to the top of the object is known as Remote Elevation Measuring REM i. Figure 6: Remote Elevation Measurement. The height of the object is displayed, from the bottom of the prism depending upon the instrument.
This feature measures the elevation of a point where a prism can not be placed directly. The measurement is extended along the plumb line while the elevation is continuously displayed. Figure 7: Remote Elevation Measurement. This method is very useful for finding distances between two points which has an obstruction between them. It is of two types:. Figure 8: Remote Distance Measurement. Distances can be obtained either in the continuous mode i.
This is required when there are obstructions in between survey line. Figure 6: Missing Line Measurement. Here two other known coordinates are required. Area can be computed of any figure just by giving the coordinates of the corner of the figure.
I would like to all informations.. Mainly i used for application for Total Station topic…Its really useful for all.. Thanks a lot for that tips…. Thanks bro and hope you will upload more suitable information about land survey along with diagrams. Sarwar Afridi Best Regards. Thanks Sir.
