SimActive Used to Control Accuracy Through Different Types of GCPs

Montreal, Canada, March 19th, 2024 – SimActive Inc., a world-leading developer of photogrammetry software, announces the use of its Correlator3D™ product along with GCP’s to enhance, extend and validate photogrammetry projects. GCPs are critical in photogrammetry projects, but there is always a trade-off in the number of points that must be collected and the associated costs.

Correlator3D allows users to import their collected GCP’s or to load previously acquired GCPs by 3rd party vendors such as CompassData. The software also enables to import existing surfaces, such as Lidar points, which can then be used to extract GCP’s.  The ability to manually create GCPs from an existing surface is beneficial to supplement field collected GCP’s where more density is needed.

“Our GCP archive contains over 70,000 points worldwide” said Philipp Humel, Vice President of CompassData. “When used with high-end photogrammetry software such as Correlator3D, and in combination with manually collected surface derived GCP’s, users can validate the accuracy of their projects.”
