2. Add the GCP (Offset) by:
   1. entering the Offset co-ordinate in the GCP list
   2. clicking the “Read GCP from Text File”  button and choose the text based file (“.csv”, “.txt”, “.dat”, “.prt”). 
3. Localize the position in the 3D viewer by clicking the left mouse button. The list of reference images is updated and the active image is shown in the viewer. 
4. Choose the “Manual Target Mode” icon or the “Automatic Mode Icon” and centre the target by clicking with the mouse in the viewer. For locating the target discs the image should be zoomed as much as reasonable for visual interpretation. Check the position of the center by changing the size of the reticule. The reticule is well-centered if the circles touch the target’s boundary simultaneously at two opposing points and in two perpendicular directions 
5. Choose at least 2 images (3 or more are recommended) showing the same GCP and click the center of target. The status signals Baseline and the Inliers turn into green and the error of re-projection and depth is displayed in the GCP list.
