Our processing software can use ground control points (GCPs) instead of the drone GPS data recorded with the photos during image acquisition, which improves the accuracy of the resulting 3D model by up to 20 times (for more information on SiteSee measurement accuracy, please consult this document).
We require our customers to use Propeller Aeropoints in conjunction with AprilTags, an easy-to-use and affordable system designed to log and process GCPs automatically. For more information on how to use GCPs, please consult our Ground Control Points User Guide.
