Graphic DNA: the application of taxonomy for the classification of environmental lettering is the title of Geraldine Marshall's PhD research. The aim of this thesis is to establish whether a taxonomy can be designed in order to produce a systematic description of environmental lettering, which will enable an informed discussion based on the interpretation of research outcomes rather than simply aesthetics.
To enable this discussion the thesis will create a method of taxonomy that will capture the visual order, style and context of lettering in the environment. Use the taxonomy to produce a systematic description of environmental lettering, which will enable an informed discussion based on the historical, social, cultural and commercial development rather than simply aesthetics. Apply taxonomy to the classification of lettering in order to advance earlier studies of environmental lettering. Establish a more flexible definition of lettering styles and their usage in the twenty-first century.
