The aerial laser scanning (ALS) dataset acquired on 24 September 2014 covers three ares of Montagne Plomb. Z1 (North Eastern part, north of crique Plomb); point density: all returns 19.30 last only 10.62 (per meter square) Z2 (central part, Eastern part of the mountain); point density: all returns 16.80 last only 10.16 (per meter square) Z3 (most western part, western side of the mountain) ; point density: all returns 17.08 last only 10.48 (per square units) Lidar Riegl LMS Q560 onboard a plane operated by Altoa, swath angle +/-20deg

The aerial laser scanning (ALS) dataset, acquired in 2004, covers three plots of Counami site in French Guiana. The laser recorded last reflected pulse. Ground points data where not delivered by ALTOA.

The aerial laser scanning (ALS) dataset, acquired in 2004, covers the Macouria area in French Guiana.

The aerial laser scanning (ALS) dataset acquired on 4 August 2014 covers eastern and western side of Bellevue de l'Inini mountain. Data acquired in the framework of DynForDiv project. Western transect point density: all returns 17.05 last only 9.83 (per square units) Eastern transect point density: all returns 16.83 last only 10.28 (per square units) Lidar Riegl LMS Q560 onboard a plane operated by Altoa, swath angle +/-20deg

The aerial laser scanning (ALS) dataset, acquired in October 2004, 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), and a digital canopy model (DCM) with a 1 meter resolution.

The aerial laser scanning (ALS) dataset was acquired on 7 and 8 August 2014 in the framework of DynForDiv project. It covers mount Itoupé (altitude 830m above sea level) in French Guiana (total covered area = 72 km²). Based on sample tiles (45, 70,192, 201, 256), the mean emitted pulse density is ~12/m², and the mean echo density ~ 19/m². Lidar Riegl LMS Q560 aboard a plane operated by Altoa

The aerial laser scanning (ALS) dataset acquired on 24 September 2014 covers eastern and western side of Montagne Trinité. Data acquired in the framework of DynForDiv project. Z1 ( East side of the montain); point density: all returns 17.83 last only 10.62 (per meter square) Z2 ( West part of the moutain); point density: all returns 18.97 last only 10.61 (per meter square)

Emprises des acquisitions LIDAR effectuées par la société ALTOA dans le cadre du projet DYNFORDIV. Ce projet cherche à analyser les structure forestière de Guyane, il est porté par l'IRD en partenariat avec le Parc amazonien de Guyane, l'ONF, et l'AMAP. Ces emprises représentes 2 acquisitions: - La montagne Bellevue de l'Inini : 04/08/2014 - Western transect point density: all returns 17.05 last only 9.83 (per square units). Eastern transect point density: all returns 16.83 last only 10.28 (per square units).
