Course syllabus
The teaching takes place in the First Semester. It consists of 6 CFU, divided into:
4.5 CFU (36 hours) of face-to-face lectures, 0.5 CFU (8 hours) of tutorials, and 1 CFU (16 hours) of computer classroom tutorials to use dedicated software tools (GIS software and specific software for geostatistical data analysis).
Lectures illustrates the typical tools and approaches of precision agriculture, introducing the theory on statistical analysis of spatial variability of data (i.e., geostatistics), and the tools for describing and modeling the spatial variability of quantities of agronomic interest (physical and hydrological soil parameters, crop parameters, etc.), and their application in precision agriculture to produce prescription maps for irrigation and fertilization.
Specifically, lectures cover the following topics (4.5 CFUs):
- innovative precision agriculture approaches to monitor the soil/crop system variability and manage agronomic inputs (i.e. water and nutrients)
- speditive techniques for proximal sensing of soils and vegetation
- theoretical elements of geostatistics:
- statistical analysis of a spatially distributed data sample
- stationarity properties of a quantity with spatial variability
- experimental variogram
- modeling spatial variability using variogram
- interpolation of spatially distributed data: kriging
- statistical tools to produce thematic maps and prescription maps
- presentation of some case studies
The tutorial hours (0.5 CFU) are devoted to the introduction and description of software tools for the analysis and representation of spatial variability of spatially distributed data (GIS, and specific software for geostatistical analysis).
Practical hours (1 CFU) take place in the computer classroom and focuse on the use of QGis, GSTAT and GeoR software (R-Studio environment)
The program is the same for attending and nonattending students

Assessment methods and Criteria
The examination consists of a written report in the form of a technical/scientific report and an oral exam. The report is related to the practical exercises carried out in the classroom using QGIS and the GSTAT and GeoR packages for geostatistical analysis and interpolation of a data sample
The candidate is required to submit the written report before the oral examination. Submission of the report is a prerequisite for admission to the oral examination.
The report will be evaluated on the clarity and completeness of the exposition of the applied methodologies and the results obtained. In particular, the candidate's ability to interpret the results obtained will be evaluated.
Beginning with the discussion of the report, the oral examination will include questions related to all topics in the program, to test the level of understanding of the topics covered in the exercise and the ability to apply the knowledge acquired.
The grade is in thirtieths and is a joint evaluation of the paper and the oral examination
Students with SLD or disability certifications are kindly requested to contact the teacher at least 15 days before the date of the exam session to agree on individual exam requirements. In the email please make sure to add in cc the competent offices: [email protected] (for students with SLD) o [email protected] (for students with disability)
