Accurate and rapid mapping of shallow water bathymetry is essential for the safe operation of many industries. Here, we propose a new approach to shallow water bathymetry mapping that integrates hyperspectral image and sparse sonar data. Our approach includes two main steps: dimensional reduction of Hyperion images and interpolation of sparse sonar data. First, we propose a new algorithm, i.e., a...
Regular gaps present on the SLC-off scenes and about 25% data is lost since the failure of the scan line corrector (SLC) in 2003. The data itself preserves good radicalization and geometry performances, and gaps occurred randomly in different images, so it's possible for cross restoration. A new method to restore the SLC-off data using another ETM+ image with near time and same extent is proposed...
