Image Index Viewer

The Image Index Viewer allows to assess radiometry for a selection of images in the project. Images displayed in the viewer are oriented relative to flight line direction, where the top of the viewer is the direction of flight. Two image scaling modes are possible to support assessment of individual images within a strip and between strips. Nadir and oblique images can be displayed
