The CAMSIS project aims to establish a network of tower-mounted multi-spectral cameras for the validation of surface reflectance products from high and very-high spatial resolution sensors. CAMSIS is an automated imaging system for the estimation of surface reflectance in the visible and near-infrared (400 – 1100nm) which captures multiple observations throughout the day for various land surface and illumination conditions. Currently, CAMSIS counts with two operational validation sites: WLEF, located in Park Falls, Wisconsin, USA over a mosaic of woody savannas and mixed forest, and ESP-VLC2, located in La Albufera National Park in Valencia, Spain over an area with tall grass and rice fields. Here we show the system characterization, data processing method, and present updates results on the validation of surface reflectance products from Sentinel-2(A,B) and Landsat-(8,9).
