A formal "FAO-type land evaluation" had been carried out by Southern Highlands Rural Development project in Papua New Guinea. The objective was next to "identify the social overlay" on this physical inventory - ie "who governs who has access to what land".

The photographs were used as aids for mapping clan boundaries and as a focus for discussion in interviews, proving an immediate way "for both interviewees and interviewers to use as a reference in distinguishing between land types".
