Surveying from an Unknown Point with Leica Total Station The total station can be used to survey in locations where you do not know the value of the point upon witch it is setup upon, this is known as Free Station Surveying. This survey technique is often used when you have two points with known established coordinate values but are not in an ideal place to perform your survey from, or at times where you wish to progress further into an unknown survey region. A good example for using this technique would be if you needed to measure points under a dense forest canopy where your GPS could not provide high precision point values. In a case like this you would use the GPS unit to establish known values around the perimeter of the tree stands and then use them as back-sights so that you can setup your total station in under the forest canopy. You would then be able to establish the value of this unknown point and then continue collecting other unknown points as well. Accurate results from this style of surveying rely on careful planning and the use of good geometry when setting up your known point. Set up is similar in many ways to the set up technique explained earlier when surveying with the total station setup over a known station.

Therefore we will assume that you can follow the steps outlined above in earlier sections for instructions on setting up the total station, leveling the unit and measuring the HI. – Create the measure job, data job and select codelist as outlined previously (all the steps are the same). – Once the above steps have been taken return back to the main menu and press the PROG key from the bottom row of the key pad. – Next select Free Station from the program Selection menu by pressing 1 on the key pad.

The station ID is a uniquely identified for the point that you are occupying. Download and install icc pro cricket 2015 for pc. It is good practice to use the point id values of the two known points that you will be measuring as this identifier. Something like pt1 or pt2 can also be used. – Enter the instrument height (HI) of the total station.

Press CONT by using the F1 key. Now you will be on the Target Point screen. – Enter the ID of the first known point you wish to use. Enter height of reflector pole with the prism above the unknown point. Aim the total station towards the reflector.
