The Joint Agency Commercial Imagery Evaluation (JACIE) team and product characterization approach

摘要

The Joint Agency Commercial Imagery Evaluation (JACIE) team is an interagency group focused on the characterization of commercial remote sensing data products. The team members include the National Aeronautics and Space Administration (NASA), the National Geospatial-Intelligence Agency (NGA), and the U.S. Geological Survey (USGS). JACIE characterizes delivered image products, focusing on three primary areas: geopositional accuracy, image quality, and radiometric accuracy. For geopositional accuracy, the team utilizes sites containing several "image-identifiable" targets and compares their known locations with those defined by the image product. For image quality, spatial response and modulation transfer function (MTF) are characterized using edge targets and pulse targets. Imagery is characterized also through the National imagery interpretability rating scale (NIIRS). Radiometric accuracy is characterized using reflectance-based vicarious calibration methods at several uniform sites. The JACIE team performed characterization of IKONOS and QuickBird products, and will evaluate OrbView-3 products.
