FORESTSCAN Project: Drone-borne LiDAR acquisition over Paracou, Oct 2019
Abstract
This dataset contains complete merged point clouds (.laz) per acquisition flight, derived raster products in .tif georeferenced format , Digital surface models (.DSM), Canopy height models (.CHM) and Digital terrain models (.DTM). The data is from multiple drone flights over different plots in Paracou French Guiana. All products are the following projection EPSG:2972 RGFG95 and UTM zone 22N. Different scanning scenarios should allow for sensitivity analyses with respect to
(i) scanning altitude (above the LiDAR derived DTM, either in terrain follow mode (AGL) or at constant altitude (AMSL)
(ii) scanning pattern main orientation
Over Plot 6 (P6): two different scan altitudes are available (80m AGL and 145m AMSL ~ 125 AGL), as well as different flight pattern main directions (75°, 345°, 120°, 165°)
Over Plots 4 and 5 (P4 & P5): altitude = 110m AMSL ~ 90m AGL, flight directions = 345°
Over PCNES & Tower: alt = 105m AMSL ~ 80m AGL and 80m AGL, flight directions = 0° and 90° \n\nOver P8: alt = 105m AMSL ~ 80m AGL; flight directions = 75° and 345°
