It can be viewed using the following software: Adobe Photoshop 9 (and possibly earlier and later software versions) via the "Open As" option or ERDAS Imagine 8.7 (and possibly earlier and later software versions). If Adobe Photoshop is used to access the imagery, the following information is required: header size (1024), width (4160) and length (varies and can be automatically calculated by Photoshop or obtained from the number of lines field in the electronic LOG file). If ERDAS Imagine is used to access the imagery, an additional computer file (.gen) will be required; refer to Mikan 213664 for further information. The imagery will appear in mirrored format and should be reoriented.Vedette-matière :Source :GouvernementAutre no d'acquisition :C0000447 -
