<abstract>Alan Stewart was Senior Survey Officer, CSIRO Division of Land Research and Regional Survey 1951-1960. He and a colleague, C.S. Christian (qv), proposed a land system survey involving the then revolutionary concept of using air photographs as an analogue model of the land resource to identify broad scale recurring patterns of land units, and then determining their characteristics by stereoscopic examination and field traverse sampling. Stewart was educated at the University of Melbourne (MAgrSc).</abstract>
