Généralités sur la provenance

1. All data was acquired by Altoa flying a helicopter between 120 and 220 m above ground level. 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 0.9µm (NIR). The scanning angle was +/- 15°. The laser recorded the last reflected pulse with a nominal precision better than 0.1 meters. The mean point density is 6 points/m². 3. Deliverance of the data in x, y, z., red, green, blue, and intensity (or return pulse). 3. The tilled data are stored in \\forestview01\BDLidar\Données Lidar\Paracou\2009\Données brutes. 4. Various further processing steps were carried out. Please get in touch with a point of contact.
