System Requirements

Correlator3D™UAV allows processing projects of any size on a single, standard off-the-shelf PC.  Originally developed for projects comprising tens of thousands of large-format images (250 megapixels each), the software’s unique algorithmsallow to rapidly process unlimited amounts of data.  It does not require extravagant hardware for this processing capability (e.g. significant RAM or cloud-based setups).

SimActive recommends using Correlator3D™UAV on a standard PC that meets the following specifications:

  • Windows 7 SP1, 8 or 10 (64-bit)
  • 8GB RAM
  • GeForce GTX series 500 or higher, certain Quadro series cards, AMD Radeon R5 series or above

Additional Information

Correlator3D™ UAV leverages from the capability of Correlator3D™ to process satellite and large-format aerial cameras.  As such, it benefits from the same software interface, modules and tools. For detailed information, please visit the Correlator3D™ section.
