Schmid, K.; Hadley, B., and Waters, K., 2014. Mapping and portraying inundation uncertainty of bathtub-type models. Data errors are an unavoidable reality in maps of present conditions, but with the prevalence of ease-of-use formats and software these errors are becoming less evident. In earlier maps, the resolution or scale of the information and its presentation on a physical medium (e.g., contours) could inherently convey a level of vagueness that corresponded to the accuracy limitations. Maps of modeled output have additional accuracy considerations, especially if extrapolating future or potential events (e.g., 100-year storm). Sea-level rise (SLR) mapping falls into this category but is also highly dependent on present topographic conditions. SLR and other ecological models use continuous surfaces or digital surface models to generate derived information; however, presentation of the uncertainty information can be difficult or confusing. A technique that conveys uncertainty boundaries for a ...
