SimActive, Inc.

Corporate Profile

SimActive is the developer of Correlator3D software, a patented end-to-end photogrammetry solution for the generation of high-quality geospatial data from satellite and aerial imagery. Correlator3D produces dense digital surface models (DSM), digital terrain models (DTM), orthomosaics and vectorized 3D features.

Utilizing the latest in advanced computer vision technology, SimActive developed patented algorithms for the generation of highly accurate dense DSMs. Featuring the world’s only GPU-powered DSM technology, Correlator3D supports rapid production of large datasets.

The DSM can then be used to extract a DTM. In this process, unique algorithms are used to automatically detect the ground and generate a bare earth model. Interactive monoscopic editing tools can then be used to further enhance the DTM.

Using the DTM as an input, Correlator3D handles the generation of thousands of orthophotos. True orthos can also be created. Fully automated seamline generation algorithms then stitch the orthophotos together to form a seamless mosaic. Advanced color balancing algorithms ensure radiometric integrity. 

To edit automatically generated seamlines, an interactive visual interface is  used with real-time updating of the final mosaic. This interface was designed to interact smoothly even with large datasets, saving users time with such operations as zooming and panning.

A further application of the DSM is found in extracting vectors. Correlator3D features an innovative semi-automatic approach for extracting 3D vectors in a highly intuitive 2D interface. Real-time feedback and analysis aids users as 3D vectors are created.

Correlator3D offers a complete photogrammetric workflow designed for large scale production environments. SimActive is committed to providing cutting-edge photogrammetry software through continuous research and development efforts. This is backed by exceptional customer support with quick, dependable responses from SimActive’s knowledgeable team.
