Correction: Tilly, N. et al. Fusion of Plant Height and Vegetation Indices for the Estimation of Barley Biomass. Remote Sens. 2015, 7, 11449-11480

After publication of the research paper [1] an error during the data analysis process was recognized. In Table 4 [1] the units for fresh and dry biomass are stated as being g/m2. However, the values actually refer to the sampling area (0.2 m by 0.2 m), hence each value should have been multiplied by 25 to extrapolate it to g/m2. Unfortunately, this step was missed out. All analyses were re-executed based on the correct values, and the corresponding tables and figures are presented in the same order as in the paper in the following Tables 1–3, Figure 1–3. Thus, the stated sensitivity thresholds for the saturation of the NDVI and RGBVI must also be corrected to be about 185 g/m2 and 1375 g/m2 for dry and fresh biomass, respectively. In comparison to the originally stated values the R2 and d values for all models did not change and hence, the overall statements of the study are correct. For the linear BRMs, the value ranges were extended through the multiplication by 25 and thus, the SEE and RMSE differ. In contrast, the log-transformation for the exponential BRMs converted the factor to a constant summand, which is added to each value (ln(25) – 3.22). Consequently, the absolute difference between the biomass values and hence, the SEE and RMSE, do not differ. We apologize for any inconvenience this has caused.
