iWitnessPRO Linker Codes

Introduced in iWitnessPRO Version 3, Linker Codes (called "Linkers") offer the traditional code functionality of auto-camera orientation as well as the new capability of construction point offsetting.

Linkers can optionally be used for fully automatic coordinate transformation between multiple photogrammetric networks via iWitnessPRO's Project Linking functionality.

Linker codes are numbered 166 to 299, being a total qunatity of 133 Linkers. Linker code size is 5.8mm dot diameter.

The 5.8mm Linker Codes can be combined with the standard 7.91mm codes (number range of 1 to 165) and the additional 5.8mm codes ranging from 300 to 981.

Using “Linker” Functionality:

In order to automatically “link” one iWitnessPRO network, to a second network, at least four Linkers are required. In a mock homicide example project, a quantity of eight Linkers were randomly placed on a hallway floor, viewed from an adjacent office room (i.e., network 1) and also the hallway (network 2). The eight linkers are highlighted in yellow - Click Here to see the Linkers. Up to twelve networks can optionally be linked in iWitnessPRO's Project Linking dialog. Code frames and code pointers were recycled from network one and re-used in network two in this project example.

The 3D “linked networks” are now ready for export to any CAD program that reads either the 2D or 3D DXF formats.


Linker Codes are sold as codes numbered 166 to 299 (133 Linkers per set) for $139.00.
