Aerial laser scanning (ALS) dataset, Crique Plomb and Montagne Plomb, French Guiana, acquired between 8 and 9 April 2009.

The aerial laser scanning (ALS) dataset, acquired between 8 and 9 April 2009, covers five plots of Crique Plomb and Montagne Plomb area in French Guiana. In this area. the forest presents contrasting and diversified characteristics: high forest, forest grown on ferricrust, and superficial saprolit with high density of stem per hectare. Ground echoes are available as well as a digital terrain model (DTM), a digital surface model (DSM), a digital canopy model (DCM) with a 1 meter resolution and a triangulated irregular network (TIN) digital terrain model with a precision of 5 meters.

Statement: 1. All data was acquired by Altoa flying a helicopter at the elevation 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 the aircraft. The wave length used was 1064 nm (NIR). The scanning angle was ±15°. The laser recorded last reflected pulse with a nominal precision better than 0.1m. The density is 5 points/m². 2. Delivrance of the data in x, y, z, red, green, blue, and intensity . 3. The data are stored in \\forestview01\BDLidar\Données Lidar\Montagne Plomb\2009\Données brutes. 4. Various further processing steps were carried out. Please get in touch with a point of contact
