From Dechant Consulting Services, Field Marker Targets (FMTs) can be used with iWitness and iWitnessPRO photogrammetry software systems. FMTs are designed for law enforcement photogrammetric measurement in tall field grass -- adjacent highway shoulders and median areas involving vehicle crash evidence. FMTs work with iWitness when combined with natural feature marking or with the Weighted Style PM's and/or Cone Style PM's. Other image-based surveying uses of FMTs include the investigation of outdoor burn (char) patterns, accomplished by fire investigators.
