Mapping the Coverage Extent of Sentinel-2
The Sentinel-2 satellite constellation plays a pivotal role in remote sensing and data science, especially in monitoring terrestrial environments. However, it faces challenges with inconsistent data coverage over oceanic regions, particularly at the edges of its coverage. This inconsistency poses difficulties for marine and coastal research, particularly in time series analysis. To mitigate this issue, we’ve developed a Python tool that leverages the Microsoft Planetary Computer API. This tool calculates and visualises the global capture extent of Sentinel-2 by processing and amalgamating extent polygons into a global raster. The resulting raster provides a pixel-wise representation of observation frequency, aiding researchers and analysts in navigating the challenges of data coverage irregularities.
