Random forest (RF) and support vector machine (SVM) approaches were applied to model soil property classifications for 3 adjacent regions: Hearst, Gordon Cosens Forest (GCF) and Abitibi River Forest (ARF). LiDAR (light detection and ranging) data was exploited to derive the detailed vegetation properties of canopy height model (CHM) and gap fraction, as well as a digital elevation model (DEM) for generating topographic covariates. The results indicate that vegetation covariates, particularly LiDAR-derived vegetation properties, were important in the prediction of the soil properties of interest. The most accurate models had accuracy scores greater than 0.7 and Cohens kappa greater than 0.5.Author owns copyright, except where explicitly noted.
