Remote Sensing for Agriculture
A.Y. 2024/2025
Learning objectives
The course aims to provide basic knowledge of multispectral optical remote sensing for environmental and agronomic applications. Explanation of physical principles of optical remote sensing, particularly with regard to the spectral response of vegetation, will be provided and characteristics of the main earth observation systems available will be presented. Emphasis will be placed on free satellite data at medium spatial resolution (e.g. Copernicus data) useful for land- and farm-scale applications. Techniques for processing remotely sensed images and their use in creating thematic maps will be explained.
Expected learning outcomes
- investigate image archives and obtain remotely sensed data
- Identify the most appropriate techniques for processing multispectral imagery and multitemporal data to generate information useful for the characterization of agricultural systems and optimized management of agricultural crops.
- critically interpret remotely sensed data in relation to variables of agronomic interest, crop system processes and environmental dynamics.
- Manage geo-spatial data and use analysis application software within workflows specific to Digital Agriculture.

Course syllabus
The course is made of 6 credits (CFU). 4 CFU corresponding to 32 hours of lectures, including seminars and practical demonstrations with dedicated software and 2 CFU consisting in 32 hours of hands-on computer lab activities.
The lectures focus on concepts and physical principles of remote sensing for environmental and agricultural spatial applications aimed at the creation of thematic mapping: i) recognition of land-use classes present in a territory, ii) assessment of the state of crops by analysis of vegetation indices, iii) approaches for estimating biophysical parameters, iv) identification of inter-field and intra-field variability, and iv) to the analysis of temporal dynamics.
The following topics will be presented:
· Physical principles of remote sensing
· Spectral response of vegetation and soils
· Acquisition systems and characteristics of digital images
· Visualization, interpretation and statistical exploration of multispectral digital images
· Computation and interpretation of vegetation indices
· Approaches for creating thematic maps
· Agricultural applications and presentation of case studies
The laboratory deals with open source tools to investigate free data archives (e.g. Sentinel data-Copernicus Program), download, process and interpret multispectral optical satellite data.
In particular, the following topics will be covered:
· Search and download of Sentinel-2 satellite data
· Basic tools for the management of satellite data and basic operations for vegetation indices computation
· Interpretation of multispectral and multitemporal satellite data
· Presentation of approaches for creating thematic land use maps
· Presentation of approaches for creating maps of biophysical parameters
· Presentation of approaches for identifying management units
· A practical case study
