Our work continues out at the low head dam site in Logansport, IN. This past July we met with Dr. Jerry Sweeten’s group (Senior Research Ecologist with Ecosystems Connections Institute) and Greg Toth (Superintendent of the Logansport Municipal Utilities) along the banks of the Eel river and captured UAV imagery of the dam. Since then, the dam has been demolished …

Nikhil and Joshua drove out to Lakewood, Ohio on November 10th, 2021 to collect data along a portion of Lake Erie’s coastline known as the Gold Coast. This mission is part of a collaborative effort with KS Associates, an Ohio-based civil engineering firm, to explore the application of UAV mapping in civil engineering projects. The goal of this mission was …

Recently, the GDSL team has focused on the ambitious goal of creating a high-resolution, multi-temporal dataset of the entirety of Martell Forest. In July we covered all 477 acres with our new DJI Zenmuse L1 LiDAR sensor. Check out the results! Through the summer and fall we’ve mobilized several times to capture the forest with our go-to photogrammetry sensor, the …

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 …
