 Offset from Nadir show the distances of the mage in relation to the Nadir of the vertical image (Maltese Cross configuration) • near (Bottom of image) • PP (Principal Point of image) • far (Top of image)

Offset from Nadir show the distances of the mage in relation to the Nadir of the vertical image (Maltese Cross configuration):

  • near (Bottom of image)
  • PP (Principal Point of image)
  • far (Top of image)
 Resulting forward overlap of the oblique image at the PP –Principal Point - when using the Nadir Image configuration as predefined in the GSD Calculator main window. Resulting forward overlap of the oblique image at the PP –Principal Point – when using the Nadir Image configuration as predefined in the GSD Calculator main window.
 Resulting sidelap of the oblique image at the PP –Principal Point - when using the Nadir Image configuration as predefined in the GSD Calculator main window. It also show the amount of additional flight lines to Left/Right to cover the Nadir of the vertical image Resulting sidelap of the oblique image at the PP –Principal Point – when using the Nadir Image configuration as predefined in the GSD Calculator main window.

It also show the amount of additional flight lines required to Left/Right to cover the Nadir of the vertical image with a certain overlap.
 Field of View and Image size of the corresponding oblique lens cones Field of View and Image size of the corresponding oblique lens cones
 Shows the camera parameters, such as flight altitude, focal lengths of the oblique lenses cones, and the optical axis of the oblique cameras. Additionally the expected image motion is calculated, based on the Groundspeed settings of the main window of the GSD calculator (default 160 kts). The image motion is display for an expected exposure time of 1/500 second. In case of a Ultracam Osprey camera, shortest shutter time is 1/750 second.
