This thesis explores potential roles for field sketching in, landscape observation and assessment, landscape planning and design, landscape representation, and
in addressing the experiential dimension of the landscape.The research seeks to define and legitimise the old technique of field sketching, and the use and development of field sketches by students and
practitioners of landscape architecture, and other landscape disciplines. The wider values of, fieldwork, hand -generated field notations, drawing as an
interactive dialogue with others, and the sketch as a type of landscape representation, are also recognised.Whilst accurate representation and precise geometrical definition of the landscape can now be achieved quickly with photographs and by semi - automated digital means, interpretation requires careful observation. Sketching
involves an observer stopping and looking and interpreting slowly and carefully. Field sketching and the uses of the field sketch are proposed as bringing an effectiveness to landscape work, valuable because of the interpretation it
involves, and the time it does take: timeless because of its simplicity.A personal way of working is investigated, based on a Grounded Theory approach. Systematic analysis of case studies is made through reflection-on-practice. Practice observations (data) are collated and interpreted by practical
sorting tasks, to propose a series of how to do and why important principles regarding field sketching. External support for the research findings is sought from literature, considering the broad themes of: fieldwork and the experience of landscapes, field sketching and drawing as craft and expression, and developing and using field sketches.Applications for field sketching to meet contemporary needs in landscape architecture are proposed: the sketch as a designer's tool, sketch-based visualisations as interpretive images, and field sketching as a participative technique that can be used to engage the inquirer, collaborators, and the public with landscape experience -grounded decisions
