4. FOPR 261 Basic Geomatics for Natural Resources Demonstration of Surveying with Total Stations OBJECTIVE At the end of this lab you will be familiar with the setup calibration and operation of the Leica Flexline TS06 Total station This demonstration will involve 1 Inspecting the survey equipment Set up and orientate the instrument Adjusting instrument settings Set a back sight azimuth Measuring instrument height Measuring prism height Booking the measured raw field data Calculating coordinates of measured points INTRODUCTION A total Station is a multi purpose electronic surveying instrument that combines an Electronic Distance Measurement EDM instrument an electronic theodolite and a computer in one unit These devices automatically measure horizontal and zenith or vertical angles as well as distances and transmit the results to a built in computer The central processor takes all these measurements and calculates the position of a point in a coordinate system EQUIPMENT Leica Flexline TSO6 total station with tripod Reflective prism Prism pole Steady sticks Hubs and axe Pocket tape Steel tape Calculator e Note book with field paper and pencil PROCEDURE Equipment inspection Tripod Begin with the tripod Inspect all nuts bolts and fasteners for tightness Test the tripod feet for tightness Loosen and tighten the tripod leg clamps checking for smooth operation Slide the tripod legs up and down checking
5. e This brings you to SURVEY 1 3 Remember this means the survey dialog on page lof 3 The PtID data field will have a default alphanumeric label Change the Starting PtID that will make sense with your grid layout For example start with point A1 and then shot point A2 e You will also need to input the reflector height hr Note that the total station will keep the previous reflector height hr value for consecutive points unless you change it manually o While still pointing a survey point change the EDM Settings mode to reflector less Non Prism Std mode if necessary for distance measurements without prisms Press FNC key and select F NON PRISM PRISM TOGGLE e Once you have input the PtID and hr you can measure the slope distance and horizontal direction Azimuth and record the point to memory o Sight the prism Sight the vertical cross hairs at the center of the rod at its base then tilt the telescope up and sight the horizontal cross hairs to the center of the prism o Press the ALL button to data collect the raw field data into memory and automatically calculate the coordinates of the survey point o Manually record the raw field data on the total station display to your field notes o Now scroll to page 3 3 by pressing PAGE key The East North and Height coordinates should be displayed o Record the rest of the grid points in the same manner You can review the recorded points after the survey is complete from MENU 2 File
