Use of Airborne Hyperspectral Imagery to Map Soil Properties in Tilled Agricultural Fields
Table 5
Correlation between predicted analyte concentrations and topographic indices including (a) relative elevation data derived from 3 m LIDAR DEM, and (b) wetness index calculated from 3 m LIDAR DEM, for one of the six sampled fields (Mason). Predicted values were calculated for unsmoothed imagery (2.5 m pixel size) and for smoothed imagery to which a low band filter had been applied. See Section 2 for analyte descriptions.
