They're relatively big players in geodesy with fleets of ships, aircraft, land vehicles gathering all manner of multi channel and spectral data at, above, and below surface level (for all the surfaces, geodetic, gravitational, magnetic, Mean Sea, etc).
They tie in with the majors that build and deploy infrastructure for oil, gas, mineral exploration and exploitation.
