PRISMA data pre-processing Webinar
March 4 @ 10:00 - 12:00 UTC+1
Hyperspectral satellite PRISMA (Precursore IperSpettrale della Missione Applicativa) is an Earth Observation satellite launched by the Italian Space Agency (ASI). This satellite has a spatial resolution of 30 × 30 m and 230 bands in the visible, NIR, and SWIR regions (400-2500 nm). The satellite’s data acquisition capability is particularly useful for monitoring crop phenology, water stress, and evapotranspiration throughout the study sites in EOMAJI project.
However, PRISMA’s images typically require pre-processing due to a co-registration issue. Co-registration is a critical step in image processing, as it ensures that pixels representing the same geographical location are spatially aligned across all spectral bands. This problem is solved by the automated and Robust Open-Source Image Co-Registration Software (AROSICS) (https://github.com/GFZ/arosics) used to automatically detect tie points or brightness edges by applying cross-correlation techniques between an input and reference band.
A webinar will be held on 4 March at 10:00 a.m. CET by CSIC showing how to pre-process a PRISMA image, including geometric and radiometric correction.
