Sun and Joshua presented their research in the 2021 Digital Forestry Retreat today. Sun’s presentation title was “Indiana Statewide LiDAR data product development and validation”, and Joshua’s presentation title was “Individual Tree Segmentation”. Both presentations were very well received by the audience.

We are hosting below LiDAR data product tile maps derived from the Indiana 3D Elevation Program LiDAR data. Normalized Digital Height Model(NDHM): Height measured from the ground surface to the top of the objects. The spatial resolution of the NDHM layers are 100ft GSD* for statewide, 5ft GSD for countywide tile maps. Digital Terrain Model(DTM): Elevation of ground surface. Only …

We (Sun, Joshua, and Nikhil) went to Logansport, IN on July 15, 2021, to collect UAS data over low head dams that will be demolished later in 2021. Dr. Sweeten’s group showed us the low head dams and also helped us locate take-off and landing locations for the UAS data collection. We also had a great discussion on potential collaboration …

Our research group gave a live demonstration of UAS LiDAR and multispectral data collection and processing in the Hoosier National Forest Research Field meeting held in Tell City, IN on June 17, 2021. Above picture is taken from one of the UAS demonstration flight (DJI Matrice 300 with Zenmuse L1 payload) and we were located in the shade (left corner …
