Supervised Sub-Pixel Mapping for Change Detection from Remotely Sensed Images with Different Resolutions

open access: yesRemote Sensing, 2017
Due to the relatively low temporal resolutions of high spatial resolution (HR) remotely sensed images, land-cover change detection (LCCD) may have to use multi-temporal images with different resolutions.
