Cone Style Photogrammetric Markers

Scene diagramming made easy with Cone Style Markers

Designed by DeChant Consulting Services (DCS) Inc., Cone Style Markers assist in measuring features of interest. Noteworthy in their functionality, Cone Markers assist in fast and accurate camera orientation in iWitness. Cone Style Markers are used by law enforcement investigators across America. The combination of Cone Markers and a digital camera affords very rapid and safe image-based mapping at the scene.
