Analysis of the accuracy in Free Station (resection) Establishment:


Best Tachy Spot analyses how the number and distribution of known points, i.e. points surveyed by total station, affects the accuracy of a Free Station.

That's how it works: 



You can determine your location with thebutton (using your GPS position). Then click onto map to locate the position of the total station and known points surrounding the instrument point (backsights). The first point is always the station.


use this button to add a target point with unknown coordinates. (backsight - green; foresight - red)


Run calculations with thebutton.


use this button to open the points and observation windows or Long-press a point in the map to get the dialog window to see the results.


                                               
Explanation of all the buttons:                                                  

Zoom/shift map - use this button to navigate.
Add known points - switch between adding points with known coordinates or points with yet unknown coordinates.
Add unknown points - switch between adding points with known coordinates or points with yet unknown coordinates.


Perform an a priori analysis - run the calculation.

Delete all points - remove the whole network including all points and measurements.

Parameter setting - set total station accuracy and standard deviation of known points 
Go to my location - show your current location on the map (using GPS).

Offline Mode - stop downloading new tiles (map).
Some functions may be hidden in the action overflow. You can reveal a list of all the hidden actions by pressing the overflow button on the right hand side of the screen(or the device Menu button, if available).
