Aerial laser scanning (ALS) dataset, St Elie, French Guiana, acquired on 7 April 2009.

The aerial laser scanning (ALS) dataset, acquired on 7 April 2009, covers two seperate areas along the track leading to St Elie in French Guiana. The northern plot has an area of 4.5 sq.km. This area covers the 100 hectares IRD-biodiversity plot. The southern area (1.4 sq.km) covers a grove of Spirotropis longifolia. The Lidar data was acquired as part of the Guyafor project. It was shared with the ESA Tropisar project and the Biomass project at Jet Propulsion Laboratory (JPL).

Statement: 1. All data was acquired by Altoa flying a helicopter between 120 and 220 m a.g.l. The embarked system was composed of a scanning laser altimeter with a rotating mirror mechanism (Riegl LMS-280i), a GPS receiver (coupled to a second GPS receiver on the ground) and an inertial measurement unit to record pitch, roll and heading of aircraft. The wave length used was 1064 nm (near infrared). The scanning angle was ±15°. The laser recorded the last reflected pulse with a nominal precision better than 0.1 m. 2. Data include point cloud ( x, y, z., time, and intensity) and flight trajectory 3. The tilled data are stored in \\forestview01\BDLidar\Données Lidar\St-Elie + Arbocel\Données brutes. 4. Various further processing steps were carried out. Please get in touch with a point of contact
