Oblique aerial photographs taken on October 27, 2013 (shot with the PALS)

The PALS was specially designed and developed by PASCO to take oblique photographs. Images can be immediately uploaded to GIS after landing because the system records the direction of the photograph and center location of the objects and camera position simultaneously when shooting.
