The shapefile provides the exact location and the attributes of the LiDAR transects including sampling method, sampling criteria, if the field data is available, who is the field data owner, the average metrics, and other relevant information. The metrics were extracted from the original point cloud, without any outlier cleaning. The EBA project collects the LiDAR transects between 2016 and 2018. Each transect covered 375 ha (12.5 km × 300 m) by emitting full-waveform laser pulses from a Trimble Harrier 68i airborne sensor (Trimble; Sunnyvale, CA) aboard a Cessna aircraft (model 206). The average point density was set at four returns per square meters, the field of view was equal to 30°, the flying altitude was 600 m, and transect width on the ground was approximately 494 m. Global Navigation Satellite System (GNSS) data were collected on a dual-frequency receiver (L1/L2). The pulse footprint was set to be below 30 cm, based on a divergence angle between 0.1 and 0.3 milliradians. Horizontal and vertical accuracy were controlled to be under 1 m and under 0.5 m, respectively. Some transects were randomly spread over the mature forest layer retrieved from the PRODES database (INPE 2019) and the secondary forest layer retrieved from the TerraClass database (INPE 2018), and other were selected to overlad field data from partners institutions. Metadata present in the shapefile: Transect = Transect id (unique identification). Field_data = researcher or project who own the field data. Hyperspect = presence of hyperspectral data.
