| 7 | 5 | Flight lines in level 1 data are as the sensor sees them (ie. appearing in the order seen by the sensor). If the aircraft is flying south, the first lines in the data will be the most northerly with later lines further south. If the plane is flying east, the first lines will be the most westerly, with later lines heading east. Navigation data is included with the level 1 imagery and can be used when producing level 3 georeferenced images. You don't need to do any manual rotation to compensate for flight direction yourself when making level 3 images - that's handled by azgcorr. |
