The first space-based geodetic and cartographical systems were designed and placed into circumterrestrial orbit, which provided high-accuracy data about the figure of the Earth and the highly detailed satellite still photographs of its surface.

Cartographical works shed light on how this erratic and intermittent process unfolded.

And how much subtler and more sensitive is Leavis's way with language in the difficult effort to suggest its own nature--"the upshot or precipitate of immemorial human living," it "embodies values, distinctions, identifications, conclusions, promptings, cartographical hints and tested potentialities" (40)--than anything linguistic science can offer.
