DJI L1 vs DJI l2 LiDAR over leaf-off deciduous forest

This dataset is a comparison of the performance of the DJI L1 and DJI L2 LiDAR packages over a deciduous forest in leaf-off season, with snow cover. It includes both the raw data and the basic processed output (laz files and DTM geotiffs).

The georeferencing is done in regards to a DRTK-2 basestation that recorded data for 3h57min (report available in the D-RTK2 folder).

The raw data direct from the L1/L2 memory cards are in the Raw_Data folder.

The parameters of each flights were: A-Flights 041 and 042 : L1 at 75m AGL, repeat scanning pattern, 3 repeat, flight direction 160° B-Flights 043 and 044 : L1 at 75m AGL, repeat scanning pattern, 3 repeat, flight direction 70° C-Flights 001 and 002 : L2 at 75m AGL, repeat scanning pattern, 5 repeat, flight direction 160° D-Flights 003 and 004 : L2 at 75m AGL, repeat scanning pattern, 5 repeat, flight direction 70° E-Flights 009 and 010 : L2 at 75m AGL, non-repeat scanning pattern, 5 repeat, flight direction 160° F-Flights 005 and 006 and 007: L2 at 100m AGL, non-repeat scanning pattern, 5 repeat, flight direction 160°

The files in the OUTPUT folders are direct output of DJI Terra processed in May 2024 using the PPP location of the base station as reference: -A-Flights : L1_75m_Rep_160deg -A+B-Flights : L1_75m_Rep -C-Flights : L2_75m_Rep_160deg -C+D-Flights : L2_75m_Rep -E-Flights : L2_75m_NonRep -F-Flights : L2_100m_NonRep
