AbstractGPU based processing for automated image correction in GISTrack: Imagery Author New technology has been developed by PCI to take advantage of modern, multi-core processing architectures and NVIDIA' s Graphical Processing Units (GPUs) to process high-resolution satellite and digital airphoto imagery. PCI's technology will allow users to perform corrections to satellite imagery not currently supported by ArcGIS Image Server and thus will allow GIS users to achieve the following with satellite imagery - Refine nominal georeferencing information by using GCPs - Correct a collection of images simultaneously (i.e. block bundle adjustment) and achieve higher levels of registration accuracy For users challenged by efficient and economical processing of large datasets, this can aid in production of typical value added products such as pan-sharpened optical imagery, image matching, or digital elevation models. The resultant imagery is suitable as base-data for high-accuracy vector extraction, for instance as input to the Multinational Geospatial Co-production Program (MGCP).
