ABSTRACT

Digital mapping offers greater fl exibility in the symbolization and composition of maps. Map designers have proved reluctant to reengineer their traditional series mapping, yet there is evidence to suggest that maps will support additional information. In the context of maps for outdoor enthusiasts, this chapter explores the addition of risk information to 1:25,000 scale mapping. After a discussion of risk, we present a methodology for combining land cover and slope, and visualizing this information by superimposing the information within the contour isoline. The chapter presents various styles, and tests them in a route selection task that shows that the visualization of risk information does indeed affect the quality of decision making, particularly among novice map users. Although the focus was on improving the design of static, paper-based products, it is clear that dynamic information (such as weather conditions) delivered over mobile devices offers the chance to convey a much richer description of risk-one that refl ects the changing dynamics of risk.
