Elevation data are critical for assessments of sea-level rise (SLR) and coastal flooding
exposure. Previous research has demonstrated that the quality of data used in elevation-
based assessments must be well understood and applied to properly model potential
impacts. The cumulative vertical uncertainty of the input elevation data substantially controls
the minimum increments of SLR and the minimum planning horizons that can be effectively
used in assessments. For regional, continental, or global assessments, several digital …
