Jason Clark

Portrait of Jason Clark


Since founding Yellowfields, Jason continues to develop the cartographic, graphic and illustrative offer of the practice and takes the lead in design work. He services clients in a wide range of sectors, including architecture, planning, transport, heritage, conservation, tourism, publishing and wayfinding. Jason keeps up-to-date through self-directed study, research and his art practice.


Jason is a cartographer and graphic designer with extensive experience across numerous fields, though primarily servicing the needs of those in transport planning, town planning, urban regeneration and the natural environment. Before founding Yellowfields, Jason worked in both the public and private sectors in cartography and graphic design.

Whilst serving in local government, Jason created the UK’s first Local Plan Proposals Map that was based upon digital vector data and a custom-designed digital workflow — over 25 years ago. Throughout his career, projects have ranged from tiling murals for a public car park through to the design and production of large technical documents used as guidance for brand/identity application or public consultation — and everything else in-between.
