Abstract:

The lecture will focus on two different issues dealing with the use of remotely sensed imagery surveyed by satellite and UAV (Unmanned Aerial Vehicles) in monitoring and managing agricultural and forestry systems. The first topic deals with the use of VHR (very high-resolution) multispectral imagery in monitoring agro-ecosystems. Imagery data provided by WorldView-3 satellite were discussed and compared with those surveyed by means of a UAV. In this latter case, issues and open questions on multitemporal/multispectral UAV surveys are discussed also focusing on geomatics aspects. A case study on olive and citrus orchards will be provided. The second topic deals with the use of free available satellite imagery in monitoring forest systems. As a reference case-study, the imagery provided by Landsat 8 Operational Land Imager (OLI) are compared to those obtained from Sentinel-2 in mapping cork oak (Quercus suber L.) distribution based on classical supervised classification techniques. Capabilities and quantitative estimation are discussed.
