Environmental Graphic Design (EGD) communicates information in three-dimensional forms and integrates messages into the built and natural environment. These messages are geared towards finding a way from one place to another, identifying a location or a specific destination, or gaining orientation in unfamiliar surroundings. This spatial problem solving process is termed wayfinding. The designer is charged with creating the tools (signs) that facilitate wayfinding, and the physical result of a wayfinding problem is a successfully concluded journey. 

Common examples of environmental graphics include directional signage systems, architectural signage, celebratory, interpretative and identity graphics, symbol, pictogram and map design. Applications of environmental graphics can be found in retail, museum, zoo, park, civic, university, health-care, sport, urban and themed environments. Environmental graphic design combines the skills of graphic, architecture, interior, landscape, lighting and industrial design. All are concerned with the visual aspects of wayfinding, communicating identity and information, and shaping the idea of place.
