    v15 v16  
    291291 * The value is measured in "ticks" and will appear quite high as the shaft encoder has a high resolution (order of millions of ticks).
    292292 * Measured in factory and provided by Leica.
     293 * Can be easily checked on the ground by following this procedure:
     294   * Start up the system on the ground (no GPS or installation required)
     295   * run BIT mode
     296   * turn off 'Position In' switch on the front panel - this will allow to snap the mirror on the centre
     297   * Read F4's tick column, it should show real scan offset and it should be within +/- 500 ticks from the -10800 value
     298   * turn on 'Position In' switch when finished
    293299
    294300
     
    308314 * An accurate ground survey (see below).
    309315 * Slow overflight for maximum point density.
     316
    310317
    311318
     
    471478 * Try to select areas where you can use the nearby geometry to help you
    472479   * e.g. follow straight road edges to where they intersect another feature, so you have more than just one pixel to guide you to the intersection point in other images
     480
    473481   * avoid using building edges (perspective shifts)
    474482 * Location of tie points
     
    602610 * We can use TerraScan for creating projects, showing trajectories, splitting and combining LAS files.
    603611 * Create new project – “first button” -> “offset stacked rectangle button”
     612
    604613 * file -> new 
    605614   * select LAS storage
