摘要
A method for augmenting Landsat-based image data providing a satellite at an orbital altitude lower than an orbital altitude of a Landsat imaging satellite; providing a set of multispectral imaging devices arranged on the satellite configured to image a terrestrial swath larger than a standard Landsat image swath, configured to always image when orbiting over cloud-free terrestrial surfaces and descending node defined along a northeast to southwest trajectory so as to correspond to Landsat archive data; synchronizing image data from at least four visible bands and a near-infrared band with a first resolution with image data from a shortwave infrared band with a second resolution; retracing the imaged terrestrial swath for one or more iterations; downlinking image data to a ground station being formatted in accordance with a data format; compositing the synchronized image data to create a cloud-free image and periodically cross-calibrating it with Landsat-based image data.
