A Map-making

Cartographic Direction

Cartography, commonly referred to as map-making, is the core discipline of Jason’s practice. More specifically, cartography can be described as the mapping of environments, experiences and data; 3D volumes transformed onto a 2D surface.

“In a world where more maps are being made than ever before, cartography doesn’t need reinvention; it needs understanding!”

/ Dr Kenneth Field

Jason designs and produces maps of all types and for all functions, whether topographical, topological, thematic or abstract. He also advises and educates on maps and mapping, helps others make maps, writes about cartographic theory and practice, and employs geographical techniques in map-based spatial analysis and research. His range of clients include private individuals as well as private and public organisations.

Bespoke and Custom Maps

Jason is particularly experienced in the design and production of large-scale and detailed bespoke topographic maps, compiled or derived from a variety of proprietary, closed and open-source data sets, including ortho-corrected aerial imagery.

Subjects have been far-ranging, including historic parks and gardens, university campuses, hospital sites, town and city neighbourhoods. The maps are themed on accessibility and movement, services and amenities, management and exploration.

“Bespoke mapping serves to more successfully encourage, inform and enhance a visitor experience of place.”

Bespoke maps can better capture the inherent environmental and experiential characteristics of a place. They can include unique details, features and visually reflect brand attributes and values. Bespoke maps also embue a more complete, accurate and unique narrative of space and place.

GIS and Spatial Analysis

Intrinsic to much cartographic output is the processing and analysis of data within a geographic information system (GIS), along with other mapping and (geo)spatial analysis tools, including photogrammetry and space syntax.

“..the potential for new geospatial technologies to unlock economic value for the UK is tremendous. From agriculture, to housing and planning, from insurance to energy production, geospatial data is being captured, processed, and analysed in genuinely transformative ways.”

/ UK Geospatial Commission

Mapping projects often begin with GIS, and related tools, filtering and shaping data before it is moved to a professional illustration application so it can be re-purposed and re-presented for publication, whether disemminated digitally and/or in print.

A Multidisciplinary Approach

Estranged Space

This is a discrete and unique arm of spatial research, defined by the collaboration of Mathew Emmett, David Littlefield and Jason Clark, blending the disciplines of architecture, art and cartography in its outputs. Estranged Space exists to be a research vehicle to examine spaces which are behind, between, beneath or otherwise separated from normative space. Zones which forgotten, hidden, neglected or simply subservient — the liminal, the beyond, the uncanny, the other, the elsewhere… the estranged. More…
