YELLOWFIELDS is a design studio specialising in the creation of maps and (info)graphics that strive to inform, engage and reveal; mapping environments, experiences and information that is purposeful, clear and accessible. This has covered feasibility studies, concept development, design, production and project management — applied most extensively within the fields of transportation (transport information systems), town planning, urban design, architecture and wayfinding.

“Yellowfields has produced an exceptionally high class bespoke map for us with intricate, accurate detailing. He was a pleasure to work with and patiently guided us through each step with useful information, helpful suggestions and samples. We are absolutely delighted with our final product and would highly recommend Yellowfields.”

—Sally Hickson, game reserve owner

A multi-disciplined practitioner

Yellowfields is led by Jason Clark MA FBCartS FRGS, a visual communications expert with 30 years of experience in cartography, information design and graphic design. He is also experienced and knowledgable in the fields of illustration, 2D and 3D visualisation. Jason’s training, education and experience are firmly grounded within the disciplines of cartography and graphic design. This has resulted in a much wider and deeper understanding of both disciplines—their history, theory and techniques—and of their application. This also forms the basis of his personal research interests.

Whilst Jason’s original training covered scribing and hand-drawing maps, he now employs a wide range of digital tools, including: Adobe Illustrator, Cartographica GIS, QGIS, SketchUp and numerous other specialist utilities. He is also gaining widening understanding and knowledge of tools and frameworks aimed at online and app-based solutions, including Mapbox, Kartograph, D3.js, JavaScript, R and Python.

Extensive experience

Jason has worked as an independent cartographer and graphic designer for the last 15 years. He has gained understanding of wayfinding, from strategy through to detailed signage design over this period, working with class-leading companies such as City ID. He has gained experience across the numerous processes and factors that impact upon this field, such as urban analysis, movement planning, information architecture and planning, user-centred design, 2D and 3D visualisation, map design, pictogram design, typeface selection, production artwork and design guidelines.

Prior to this he spent over 10 years working in London, firstly as a Graphic Designer and Cartographer at Nathaniel Lichfield & Partners, now Lichfields (national town planning, design and economics consultants), then latterly, as a Principal Consultant in Visual Communications at Steer Davies Gleave, now Steer (international transport, infrastructure and economics consultancy). Jason’s early career was spent in local authorities running graphic design and cartography functions. He implemented a digital workflow solution between a geographical information system (GIS) and desktop publishing (DTP) system in the mid-90s that saw the the UK’s first Local Plan produced that was derived from large-scale Ordnance Survey (OS MasterMap) data—vector, not raster as was the norm.

“Yellowfields went beyond our expectations to ensure that the project was delivered to our requirements. We were kept fully informed throughout the design process. Jason completed the project on time and to budget. We highly recommend Yellowfields’ design services.”

—Richard Lawrence, Derby City Council

Collaborative practice

The practice is fundamentally collaborative, whether with the client directly, and/or with partners across other disciplines—working with you, not for you. Process is fundamental; not pre-determined solutions. The end result will emerge naturally if the methodology is correct.

Today, Yellowfields is focused on cartography (map design and production), including illustration and information design. This includes all kinds of special purpose and thematic mapping such as concept (abstract) mapping, line diagrams, location plans, grounds/estate maps. visitor maps, gaming maps, recreational maps, transport network plans and other topographic maps. Though based in south Devon, Jason has worked on projects throughout the UK and much further afield, including Italy, Russia, United Arab Emirates and the United States. He continues to do so for a wide range of clients across all sectors.


Jason is a Fellow of the British Cartographic Society (FBCartS), a Fellow of the Royal Geographic Society (FRGS) and an Affiliate of the Royal Town Planning Institute (RTPI); the original class of a Technical member (TechRTPI) ceased in 2016.

This site represents a mere snapshot of projects over more recent years. Whether you need an office location plan or an entire city mapped for a pedestrian wayfinding scheme, Jason is happy to chat about your ideas or requirements, so drop him a line. A resumé, Terms & Conditions (T&Cs) of engagement and his Professional Practice note are available on request.
