Are Feature Agreement Statistics Alone Sufficient to Validate Modelled Flood Extent Quality? A Study on Three Swedish Rivers Using Different Digital Elevation Model Resolutions

Table 2

Different flood verification measures implemented for raster and vector data (revised from Hunter [9]).

Verification measures	Binary classification (raster-based)	Areal size (vector-based)	Values
Feature agreement statistics:
			0 to 1
			−1 to 1
			−1 to 1
			−1 to 1
Hit rate/probability of detection (POD)			0 to 1
Probability of false detection (POFD)/false alarm rate			0 to 1
False alarm ratio (FAR)			0 to 1
BIAS			0 to ∞
