Key words: catchment function analysis; catchment management; DeGrey; Google mapping. Introduction The importance of understanding the main components of landscapes, and the interrelationships among them, is rising with the threat of significant impacts of climate change and the persistent pressure to lift agricultural productivity while preserving or enhancing ecosystems. Adroit observation of subsystem interactions and the use of new knowledge to scale them up to relevant systems levels will be central to progress in this domain. This paper reports such an approach. The purpose is to explain a novel process for analysing comprehensively a catchment (the
