Visualization of gridded scalar data with uncertainty in geosciences

Evaluating Sketchiness as a Visual Variable for the Depiction of Qualitative Uncertainty

“…Amongst all color dimensions, saturation is often preferred because the reduction of color purity conveys more intuitively the notion of degrading data quality or confidence [31,45]. Hue is also used [39,55,56] and rainbow scale is often chosen to map ordinal uncertainty data up to seven levels-despite of its lack of perceptual ordering [6]. For value, darker lines suggest more certainty about an aspect of the underlying data.…”

Uncertainty-Aware Multidimensional Ensemble Data Visualization and Exploration

“…Similarly, visual variables such as color [10], [20], brightness [8], [21], blurriness [22], and texture [7], [23] can also be employed to encode uncertainty. The geometry based approaches are a family of techniques that adapt the basic geometry to represent uncertainty, including point [20], line [24], cube [25], and surrounding volume [10], [26]. Coninx et al [27] and Lundstrom et al [28] demonstrate that animation can be used to express uncertainty as well.…”

Correlation Visualization for Structural Uncertainty Analysis

“…The majority of approaches has focused on visualizing the positional variation of isosurfaces and material boundaries in 3D uncertain scalar fields. The proposed strategies range from the visualization of confidence surfaces [5,21] and flowlines [22], to surface diffusion techniques [23] and surface animations [24]. The most recent approaches [25][26][27] suggest modeling the uncertainty stochastically and deriving probability distributions for particular events associated with isosurfaces, such as the crossing of these surfaces along the view rays.…”
