Creating Tie Points

Tie points can be created in either of the following ways:

§  By selecting in the Photos list the photos between which you want to establish a correspondence. The Control Point Editor opens with the Photos panel populated by the selected photos. You can also select photos after opening the Editor. See "Creating Tie Points in Selected Photos" in this chapter for information.

§  By creating a tie point from an easily identifiable location on the terrain. The Control Point Editor opens with the Photos panel populated by the photos whose frustum intersects with the created point. See "Creating Tie Points from Identifiable Locations on the Terrain" in this chapter for information.

After creating a tie point, you mark it in the relevant photos using the Control Point Editor. See "Marking Control Points in Photos" in this chapter for information.
