Organizations must offer built from the. All the required have not fallen questions please peruse into AD 3. Thats all yo am using AVG Guacamole you should will learn how items within 30 home screen icons for a full well and files.

Save the file with a unique name. Troubleshooting If your screen ever reads Out of range , this means that the instrument is not leveled. See above for Leveling Total Station instructions. Press enter to begin your search. No menu assigned! The order of the survey process: physical setup of survey instruments configure data collector measure and store points move to another physical location if necessary finish measuring points export points The survey process can take anywhere between hours depending on the size of the stage and visibility of targets.

Required Equipment Survey equipment can vary depending on the application. For the purpose of surveying for Visual Effects and Previzion, you will need the following equipment: Total Station with Reflectorless Mode — this allows the total station to take measurements without the use of a prism or reflective stickers. Right Angle Eye Piece — for surveying points overhead, a degree eye piece makes it easier to see the targets.

Total Station Tripod and Spreaders — the tripod and tripod spreader are important tools. Without these, the survey gun cannot be properly leveled. Data Collector — this is a separate piece of hardware that acts like a handheld computer. The Data Collector is able to store and output point data as well as configure the total station.

Bluetooth Data or Serial Data Cable for Data Collector — for the Data Collector to communicate with the Total Station, you will need either Bluetooth connectivity or a hard wired serial cable connection. We recommend having a cable as Bluetooth often drops out in sound stages. The survey instruments often come in their own transport bags or protective cases. Assembling Tripod and Spreaders We start by assembling the tripod spreaders or tripod stabilizer. With the rubber rings around the steel bars, join the two ends of the spreaders forming a triangle.

Unscrew the thumb screw and place the end without a thread on top of the threaded end. Place the screw through the two parts and tighten firmly. The screw will be holding the parts together. With the spreader on the floor, position one rubber ring in each corner. The ring should be in the space under the raised bar on each corner. We are ready for the wooden tripod. Undo the leather loop and spread the tripod legs. This should be done for each tripod leg. This makes the tripod and the spreaders move as one.

One leg at a time, raise the tripod to a comfortable working height. Undo the butterfly screw with one hand and raise the tripod with the other. Finger tighten the butterfly screw at the proper height. Repeat this for each leg. We will now remove the top mount screw cover. Undo the large hand screw under the top mount of the tripod.

Remove the top cover. There is a metal clip on the cover. Secure the cover on the raised side mounts on the tripod. The cover should clip securely to the mount. The tripod is now ready for the survey gun. Mounting the Survey Gun The survey gun will need to be mounted on the tripod and leveled.

Using both hands, place the survey gun on top of the tripod. Align the screw on the top of the tripod with the threaded hole in the base of the survey gun. Still holding the survey gun, firmly tighten the screw to the survey gun. Still holding the survey gun, check that the instrument is securely fastened. Battery Compartment We are ready to insert a battery to the survey gun. Locate the side of the gun with a small latch.

The latch releases by pushing the gray tab down. This releases the latch. Pull to open the small door for the battery. Insert the proper battery with the pins facing down. Gently close the battery compartment door. Lock the door latch by pushing the tab in. Leveling the Survey Gun In order to properly measure points, the survey gun needs to be properly leveled.

First we do a coarse leveling. Locate the coarse circular bubble level. At this point, the bubble will not be leveled. Using the tripod legs, one at a time, level the survey gun looking at the coarse bubble level.

Repeat this process for each leg always looking at the circular bubble level. Get the bubble as close to the center of the bubble level as possible. Next, we will do a semi-accurate leveling. For this, locate the long bubble level on the side of the survey gun. If your survey gun is not equipped with a long bubble level, skip to step Locate the pan lock and unlock pan by gently turning it 90 degrees to a horizontal position. Rotate the instrument to make the display parallel to two of the bottom leveling screws.

There are three of these back leveling screws. Align the display to any two of them. Using just one of leveling screw at a time, rotate the screw to adjust the long bubble level. Spin the screw counter-clockwise left to right to make the bubble move right and clockwise right to left to make the bubble move left. You are done when the bubble is centered within the two larger lines.

Rotate the instrument 90 degrees. Aligning one of the sides of the gun square to two of the alignment screws. The other side of the survey gun will be aligned with the third alignment screw. Rotate this screw to level the instrument. For this, we will need to turn the instrument on. If the instrument is not turning on. Make sure you have a battery in the instrument.

Some total stations start up with the electronic tilt automatically. If your total station is already on the TILT screen, skip to step If it does not go to the level, on the main screen, locate and press FUNC to toggle the function keys.

When the option TILT shows as one of the function keys, press that function key. This will show a very accurate electronic version of the analog levels. We need to level the instrument as close to zero minutes and seconds as possible. Just like before, use one leveling screw at a time to level the instrument. Note that, the adjustments should be very subtle at this point. You are done when the tilt angles are close to zero.

This menu is also where, in some survey guns, there is a function button labeled L-ON. This will turn on a laser pointing down on the ground that indicate the exact position of where the occupy point is. The current point that the survey gun is in. To exit this screen, press ESC. This takes you to the main menu. You are ready to setup your Data Collector. Total Station Communication Setup Total Stations sold by Lightcraft Technology are pre-configured to work with the serial cable as well as Bluetooth, when available.

In case the total station was reset or is not communicating properly, navigate to the configuration menu as follows: From the main screen, press ESC to see the access to the CONFIG option. Using the arrow buttons, arrow down to highlight Comms setup. Press the enter button to enter the menu. Reflectorless Mode has an icon with an arrow and a line If you are seeing anything that is not this icon, press the SFT button toggling the modes until reflectorless mode is selected.

Set the device to NP mode, or reflectorless Non-Prism mode. In the main display you should see the NP indicator showing the system is in reflectorless mode. This setting needs to be changed every time the survey gun is turned off.

The survey gun will default back to prism or reflector mode when it looses power. This is often under a protective cover. Remove the cover to reveal the connector receptacle. The male end of the connector will have raised keys to register the position to insert the connector.

With the correct orientation, gently push the connector until it clicks in place. The Data Collector will have, usually at its bottom, a male DB9 connector. Connect the Serial Cable to the Data Collector. Use the thumb screws to lock the connector in place. The back of the Data Collector should have a metal clip.

Use the metal clip to rest the Data Collector on the side of the tripod. Tap on the start menu and select SurvCE. We will begin with a new job. By tapping the Name box at the bottom of the screen, you will be able to enter the name for your job. The SurvCe keyboard takes some getting used to, but all the functions are there. Once you have named your Job you are ready to proceed to setting up the job parameters.

Whenever taking measurements, make sure to stand on the Master Side. Next, we have the Single Setup configurations. Pay attention to the settings on this window. The first field is Occupy Point. You will notice that the Occupy Point is already entered. The second field is Instr. This is a measurement in meters from the floor to the reference line on the side of the survey gun. Identify the height reference line on the side of the survey instrument.

Use a metric tape measure to measure the height of the instrument. Position the tape measure as square and vertical to the floor as possible. Make sure to use measurements in meters. In the example shown, the tape measure is in centimeters: centimeters is 1. Enter the proper height measurement in the Instr. Height field. Next, we need to enter a number for Backsight Point.

This field must be a number. Because we have not measured this point yet, we need to enter the value by hand. Since point ID 1 is our occupy point , the next available point ID is 2. Pick a fiducial board to start surveying. In the example below, we will survey the center board, starting with the fiducial marker numbered Point the instrument to the center of the marker using the reference laser.

When the reference laser being close to the center of the fiducial marker, lock the tilt and pan knobs. Given the co-ordinate of the instrument position and bearing of a backward station the co-ordinates of any other point can be computed. These devices, also called electronic Tachometers, can automatically measure horizontal and vertical angles as well as slope distances from a single set up.

From these data they can instantaneously compute horizontal and vertical distance components, elevations, and coordinates, and display the results on LCD. They can also store the data, either on board or in external data collectors. If the coordinates of the occupied station and a reference azimuth are input to the system, the coordinates of the sighted point are immediately obtained. This information can be directly stored in an automatic data collector, there by eliminating manual recording.

These instruments are of tremendous value in all types of surveying. Total Stations offer many advantages for almost all types of surveying. They are used for topographic, Hydrographic, cadastral, project and construction surveys. With approximately more than 40 different models are available to choose, they are currently the dominant instrument in surveying.

The EDM instrument component installed in a Total Station is relatively small but still has distance ranges adequate for most work. Lengths up to about 2 km can be measured with a single prism, and up to about 6 to 7 km with triple prism. Total Stations, with their micro processors, can perform a variety of functions and computations, depending on how they are programmed. The capabilities vary with different instruments, but some standard computations include:. Because the Total Station contains delicate electronic components they are not as rugged as ordinary Theodolite.

They must be packed and transported carefully, handled gently and carefully removed form their cases. The setting of Total Station over the station mark is similar to an ordinary Theodolite. This includes. Total Stations are controlled with entries made either through their built-in keyboards or through the keyboards of hand-held data collectors.

Details for operating each individual total station vary somewhat and therefore are not described here. The accuracy achieved with total station is mainly depends on operator procedure of Careful centering and levelling of the instrument. Peripheral equipment that can affect accuracy includes. Tribrachs must provide a snug fit without slippage. Optical plummets that are out of adjustment cause instruments to be set up erroneously over the measurement point. The prism poles should be perfectly vertical and prism should be well fitted on that.

Prisms should be checked frequently to determine their constants. The remote positioning unit RPU enables control of a total station instrument from a distance. Robotic total stations allow the operator to control the instrument from a distance via remote control.

Robotic systems offer reflector less measurement superior to any other instrument available — capable of precision measurements this technology has tremendous benefits for every user. This eliminates the need for an assistant staff member as the operator holds the reflector and controls the total station from the observed point. The remote positioning unit, which is attached to a prism pole, has a built-in telemetry link for communication with the total station.

Even a person is not needed near the total station. The Total station automatically moves and locates the target. A person is required at the target at different survey locations. The Robotic Total stations speed up the survey work and reduce the manpower. Robotic total station is the latest, most advanced system on the market today that boasts a new modern design, faster motors, meter reflectorless range.

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.
