Radiometric Characteristics of Geostationary Ocean Color Imager (GOCI) for Land Applications
Korean Journal of Remote Sensing, 2012 The GOCI imagery can be an effective alternative to monitor short-term changes over terrestrial environments. This study aimed to assess the radiometric characteristics of the GOCI multispectral imagery for land applications. As an initial approach, we compared GOCI at-sensor radiance with MODIS data obtained simultaneously.
