Correlator3D for Quebec - 27/04/2011


The Geomatics Centre of Quebec (CGQ, Canada) has completed a major mapping project using SimActive Correlator3D. The project was done in collaboration with the Nippour Group, whose responsibilities included extensive quality assurance.


The project involved processing more than 2,200 scanned films at 21cm ground sampling distance (GSD) and generating digital surface / terrain models (DSM/DTM) with 1m grid post spacing.  More than 350,000 ground control points were then collected through real-time kinematic GPS by Nippour, and the average vertical error of the final DTM was shown to be less than 27cm.


Professionals who like to experience a live demonstration of Correlator3D at ASPRS 2011, to be held from 1st to 5th May in Milwaukee, Wisconsin, are requested to send an email to or visit booth 323.
