Use this dialog for all accurate tiepoint measurements needed in the Aerial Triangulation process.
With this dialog you can also inspect the different tiepoints at any moment.

Selecting this menu from Strabo's View menu will show the next dialog:

1. The actual list of the tiepoints.
2. Number of Unique Points: this is the number of tiepoints.
   Each tiepoint is expected to be measured in at least 2 images and gets the same name in the different images where it is measured in.

   This dialog shows all existing measurements of the requested tiepoint in an extraction of the image.
   Every image detail window refers to an image where you have measured the tiepoint.
   In these windows you can investigate, add, delete or remeasure the tiepoint.
