In section 3.n. the rules mention that we must know methods of studying glaciers: Altimetry, radar . . . but as far as I can tell radar is a type of altimetry. Does altimetry refer specifically to laser altimetry, while radar refers to radar altimetry? Did I misunderstand something?
An altimeter measures altitude. Radar can be used for altimetry while it can also be used to study the interior of glaciers, measure thickness of ice, etc.
