Algeria’s imaging capability, engineering partnership and the evidence behind a map
Follow Algeria’s first satellite and its medium-resolution successor through engineering, image sampling, map production and long-term service.
Suggested preparation is listed in the course · Start whenever you’re ready
Copernicus Sentinel-2 observed northern Algeria on 12 August 2021. ESA’s processed image retains its place labels, burn-scar annotation, date and scale bar. It is a different instrument and date from the Aqua view, not an Alsat acquisition or a controlled resolution comparison.
