Its use in large mammal research for size and/or mass estimation has proven extremely beneficial. Recent photogrammetric technique advancements have improved its applicability in the field, although some analytical components remain time consuming. The use of automated coded targets, associated with commercially available software, was evaluated to simplify photogrammetric analysis without compromising its practicality. The effects of variable target size and shape, lighting conditions, number of photographs, photograph target coverage and project processing time were assessed. Augmenting a published photogrammetric field technique by including coded targets greatly reduced analysis time. The simplified method is attractive for use by a wider range of both specialist and non-specialist users for applications within the animal photogrammetry field.
