The logo used for e-Foto is based on a fiducial mark. These marks are located on every aerial photograph taken from a photogrammetric camera, and have calibrated coordinates. They help establish a relationship between image and camera coordinates. This relationship is known as “interior orientation”.
Today, some photogrammetric instruments no longer exhibit these marks. However, its contribution to the development of this science was so important, that we decided to keep a stylized version of one of them as our official logo.
