Aerial laser scanning (ALS) dataset, Nouragues, French Guiana, acquired in 2007.
The aerial laser scanning (ALS) dataset, acquired in 2007, covers the research area in the Nouragues reserve. Ground echoes are available as well as a digital terrain model (DTM), a digital surface model (DSM), and a digital canopy model (DCM) with a 1 meter resolution.
Origine de la donnée :
- 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-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 0.9 µm (near infrared). The scanning angle was ±30°. The laser recorded the last reflected pulse with a nominal precision of better than 0.1 m. The density of points is 3 points/m². 2. Delivery of the data in LAS 1.2 format (tiled) 3. The data are stored in \forestview01\BDLidar\Données Lidar\Nouragues\2007. 4. Various further processing steps were carried out. Please get in touch with a point of contact.
