Online Data Portal for Indiana 2017-2019 3DEP LiDAR Database

Our team launched Online Data Portal for Indiana 2017-2019 3DEP LiDAR Database (lidar.jinha.org) to help users easily and effectively find statewide LiDAR point cloud and data products. Please click on the county name in the below section to navigate to visualization/download page. Currently, we provide below data products:

Point cloud, digital terrain model (DTM), normalized digital height model (NDHM) from the left
  • Point Cloud (.laz): sets of points (x, y, z, intensity, etc.) that describe an object or surface
  • Digital Surface Model (DSM, .tif): 3D representation of surface elevations in raster image format, 5ft by 5ft
  • Digital Terrain Model (DTM, .img): 3D representation of underlying terrain elevations in raster image format, 2.5ft by 2.5ft
  • Normalized Digital Height Model (NDHM, .tif): 3D representation of heights above underlying topography of man-made objects, vegetation, etc. in raster image format, 5ft by 5ft

2020 ISSR&D Conference Presentation by Joshua Carpenter

Joshua presented his research on the use of spaceborne LiDAR data for measuring crop heights in the 2020 ISSR&D Conference today (9/24/2020). His presentation was very well received by audience.

Joshua is explaining how crop height measurements are done using spaceborne LiDAR data.
