Refining The Georeferencing Of Prisma Products Using An Optical Flow Methodology

Georeferencing and orthorectification of images plays a vital role in ensuring accurate and reliable geospatial data. They improve distance measurement precision, facilitate data integration and comparison, enhance geospatial analysis, and enable meaningful visualisation and interpretation of imagery. In this contribution, we describe the processing pipeline developed at Kuva Space to refine the georeferencing and orthorectification of PRISMA products using optical flow algorithms. The proposed method achieves subpixel accuracies and has the ability to run a full scene in under one second.
