| description | High frequency of images and high spatial resolution are necessary characteristics in studies with high temporal and spatial dynamics, which are difficult to find in a single orbital sensor. Therefore, the possibility of using multiple satellites to overcome this obstacle in monitoring is of fundamental importance. The aim of the study was to evaluate the multi-sensor coupling for the monitoring of phenomena that require a greater frequency of spatial detail and high-temporal observations by intercalibrating the reflectance images of the LISS III sensor, which is on board the satellite ResourceSat-II, and the MSI sensor onboard the Sentinel-2A, utilizing the Landsat-8 OLI sensor as standard. To perform the methodology, prior the intercalibration, it was necessary to convert the digital numbers of the bands into reflectance at the top of the atmosphere, so that intercalibration of data with simple linear regression could be subsequently performed. The results demonstrate that, with the intercalibrations of the reflectance images of the LISS III and MSI sensors, it is possible to couple the information of these sensors with those coming from OLI, enabling the increase of the frequency and availability of information in studies that require more observations, as in agricultural monitoring, natural disasters, and deforestation among others. |
