There are a number of commercial providers of VHR imagery. Below is a non-exhaustive list of missions currently orbiting and collecting data, together with the maximum spatial resolution they can collect:

  • Maxar ​

    • WorldView-2 (50 cm)​

    • GeoEye-2 (46cm​)

    • WorldView-3 (31 cm)​

  • Airbus​

    • Pléiades 1 (50 cm)​

    • Pléiades Neo (30cm – just launched)​

  • Satrec (Korea)​

    • Komsat (50cm)​

  • Planet ​

    • Skysat (50 cm)

Whilst the polar regions are not as well served by commercial providers as the rest of the world, there is now a large archive of imagery collected by MAXAR's satellites which can be exploited.

MAXAR imagery is therefore often the go-to choice for Antarctica.
