The aerial laser scanning (ALS) dataset, acquired in 2004, covers the Sinnamary area in French Guiana.
- All data was acquired by Altoa flying a helicopter between 120 and 220 above ground level. The embarked system was composed of a scanning laser altimeter with a rotating mirror mechanism (Riegl LMS-Q 140i-60), 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 905 nm (NIR). The scanning angle was +/- 30°. The laser recorded the last reflected pulse. The mean point density is 7 points/m². 2. Delivrance of the data in x, y, z., time and intensity (or return pulse) 3. It is not totally clear if the data are in UTM22N WGS84 or CSG67 3. The data are stored in \forestview01\BDLidar\Données Lidar\Sinnamary\Données brutes. 4. Various further processing steps were carried out. Please get in touch with a point of contact
