From DeChant Consulting Services, Florescent Orange Passive Targets (PTs) can be used with all three versions of the iWitness photogrammetry software system. Florescent photogrammetric targeting is superior in performance to traditional monochrome photogrammetric targets. PTs are 1.4-inches (36mm) square. The adhesive back targets are inexpensive for using one time, or can optionally be recycled many times over with the supplied wax paper sheets. There are 4 edge "tick marks" so the target centerline can be indexed to an edge, for alignment purposes. The backer is easily removable, for fast application in the field.
