New Image Point

Points can be computed when:

Points can be computed when:

Using the image group viewer and selecting a common target feature from the image, the forward intersection from each image position arrives at a 3D intersection point. These points from images are stored to the points and have the point role computed.

To create new points from images:

To create new points from images:

1.	Select New Point either from the ribbon bar or the context menu.
2.	Mark the target point in the first image.
3.	Mark the target in the second image.
4.	Once the target has been selected in two or more images the projected point is shown.
5.	Add thematic data if needed.
6.	Select Create to store the point to the project.

When working with GS18 I images, the default mode for point creation is the automatic target selection mode. With this method, a single click defines the point. For other cases, the intersection mode is automatically set to manual, and the point can be created after being marked on two or more images.

The computation of image points is following the same principle as with point averaging. You set a tolerance threshold for which the computed 3D point quality is acceptable and when the results are within this tolerance a position is computed. When the 3D accuracy is outside of that tolerance, then no point is computed.

Set the image point accuracy in the Points & Angles options page.
