At our trial site at CIAT headquarters, we have been acquiring weekly Unmanned Aerial Vehicle (UAV) acquisitions and coincident ground measurements over multiple 20m x 20m subplots of Brachiaria humidicola, Brachiaria Mulato and Brachiaria Brizantha Marandu. The slide show below outlines some of the process. We`re combining these observations with satellite acquisitions to develop a multi-source remote sensing based approach to monitor and manage tropical forage-based production systems.
