Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN><SPAN>Davey Resource Group utilized LiDAR and aerial imagery to identify tree canopy cover and land cover classifications. Advanced image analysis methods were used to classify, or separate, the land cover layers from the overall imagery.
