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. The semi-automated extraction process was completed using Feature Analyst, an extension of ArcGIS</SPAN></SPAN><SPAN><SPAN>®</SPAN></SPAN><SPAN><SPAN>. Feature Analyst uses an object-oriented approach to cluster together objects with similar spectral (i.e., color) and spatial/contextual (e.g., texture, size, shape, pattern, and spatial association) characteristics. </SPAN></SPAN></P><P><SPAN><SPAN>Contact: Department of Environmental Services</SPAN></SPAN></P><P><SPAN><SPAN>Data Accessibility: Publicly Available</SPAN></SPAN></P><P><SPAN><SPAN>Update Frequency: Never</SPAN></SPAN></P><P><SPAN><SPAN>Last Revision Date: </SPAN></SPAN><SPAN><SPAN>11/22/2024</SPAN></SPAN></P><P><SPAN><SPAN>Creation Date: </SPAN></SPAN><SPAN><SPAN>11/22/2024</SPAN></SPAN></P><P><SPAN><SPAN>Feature Dataset Name: Tree_Canopy</SPAN></SPAN></P><P><SPAN>Layer Name: Tree_Canopy_2018_poly</SPAN></P></DIV></DIV></DIV>
