UNMANNED AIRCRAFT SYSTEMS AND SATELLITE TECHNOLOGIES FOR TOPSOIL MAPPING IN PRECISION AGRICULTURE

Abstract. The use of satellite/UAS technologies in Precision Agriculture (PA) is increasing significantly and the continuous need such kind generating a great economic impact. This study carried out results by using Unmanned Aircraft Systems (UAS) Very Hight Resolution (VHR) satellite imagery for estimation topsoil variability. purpose this contribution concerns data analysis over two Production Units evaluating radiometric response along surface (e.g., spectral index). Our concern integration UAS satellite, improving accuracy soil homogeneous areas variability, which to manage agricultural practices. remote sensing covered bare were isolated from vegetative matrix area. Thus, statistical approach through correlation between specific indices, it could be possible determine variability each pedological context, determining zoning land plots. According this, absence high-resolution proximal instrumentation, can provide preliminary information suitable establish weighted topsoil/subsoil sampling campaign.
