Automatic aerial triangulation (AAT) was performed. The triangulated frames were rectified to a LiDAR derived DEM. Mosaicking was performed using an automatic seaming algorithm and manually edited to eliminate seams through elevated features where possible.<span style='color: rgb(0, 0, 32); font-family: "Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 17px;'><br /></span></div><div style='color: rgb(76, 76, 76); font-family: "Avenir Next", Avenir, "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; background-color: rgb(255, 255, 255);'><br /></div><div style='color: rgb(76, 76, 76); font-family: "Avenir Next", Avenir, "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; background-color: rgb(255, 255, 255);'>Imagery was captured mainly in the Spring of 2020, with limited areas captured in November 2020. </div>
