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 …
