Think for a while about the vast area of Antarctica that is covered by gently sloping ice. Much of that area, especially in the interior of the continent, has neither been visited on the ground, nor covered in detail by air-borne surveys. How are topographic contours to be drawn on maps of such areas? The answer is either by joining up the few available dots and tracks aided by guesswork, or by using satellite radar altimetry. Herzfeld’s book presents a new series of maps of Antarctica derived from satellite radar altimeter data showing topography of the ice/snow surface. This is...
