4 Multisource Image Fusion and Classification
Earth-observing satellites currently in operation or planned for the near future carry sensors that operate in the visible, infrared, and microwave regions of the spectrum. They often provide two images for a particular location at a specific instant, called multimodal imaging: a multispectral (MS) image and a panchromatic (PAN) image. Multimodal remotely sensed imagery is now being generated at an unprecedented pace, with sources such as Landsat, MODIS, and Sentinel-2 contributing rich spatial and spectral information that significantly enhances land cover mapping. A crucial element in achieving successful classification is the effective use of abundant multimodal ...
