The first step was the data download. Two sets of archive satellite images were used. The first one consisted of six images acquired between March and December 1995 by the ERS-1 satellite. The second dataset was acquired by the COSMO-SkyMed mission between May and December 2016, and consisted of seven images. The main characteristics of the two aforementioned sensors are summarized in Table 1. Details about the processed datasets are provided in Table 2. These two datasets provided, respectively, the two Sarno River basin impervious area scenarios under analysis.
