Guyadiv is a network of permanent forest plots installed in French Guiana. The site of Eperon Barré is composed of two plots : one 1ha-plot and one 100x200m-plot. A complete inventory has been made in 2009 and 952 trees with dbh>=10cm have been registrated. 535 and 405 species have been identified in the two plots. 99,1% and 98,3% of the registrated trees have been identified to the species level. We only have the point coordinates and not the precise demarcation of the sample plots. In order to calculate the bounding box for these plots, we have expanded the point location 500 meters in each direction.

The aerial laser scanning (ALS) dataset, acquired on 7 April 2009, covers two seperate areas along the track leading to St Elie in French Guiana. The northern plot has an area of 4.5 sq.km. This area covers the 100 hectares IRD-biodiversity plot. The southern area (1.4 sq.km) covers a grove of Spirotropis longifolia. The Lidar data was acquired as part of the Guyafor project. It was shared with the ESA Tropisar project and the Biomass project at Jet Propulsion Laboratory (JPL).

The site Toponowini is composed of four 3km-transects (20m wide). 4603 trees with dbh>=20cm have been recorded by Office national des forêts (ONF). Fauna inventories have been made by Office national de la chasse et de la faune sauvage (ONCFS) few days after. 506 under-storey plants have been recorded on 20 25m²-plots by Institut de recherche pour le développement (IRD). Soils have been described using 23 samples (1.20m depth max.). Laboratory analysis are available for two soil-profile.

The site Saut Parasol is composed of four 3km-transects (20m wide). 4423 trees with dbh>=20cm have been recorded by Office national des forêts (ONF). Fauna inventories have been made by Office national de la chasse et de la faune sauvage (ONCFS) few days after. 716 under-storey plants have been recorded on 21 25m²-plots by Institut de recherche pour le développement (IRD). Soils have been described using 20 samples (1.20m depth max.). Laboratory analysis are available for one soil-profile.

The site Crique Galibi is composed of 3 3km-transects (20m wide). 2861 trees with dbh>=20cm have been recorded by Office National des Forêts (ONF). Fauna inventories have been made by Office national de la chasse et de la faune sauvage (ONCFS) few days after. There is no inventory of under-storey plants on this site. Soils have been described using 16 samples (1.20m depth max.). No laboratory analyses available for soils.

The aerial laser scanning (ALS) dataset, acquired between 6 and 7 April 2009, covers the experimental station Paracou in French Guiyana. More precisely, the dataset covers 9 plots totally (Paracou 4, Paracou 5, Paracou 7, Paracou 8, Paracou 9 - Paracou 12, and Paracou 14) and 4 plots partly (Paracou 3, Paracou 6, Paracou 13, and Paracou 15). The area includes exploited and non-exploited forest and Pinot palm. Ground control points are available. The Lidar data was acquired as part of the Guyafor project. It was previoulsy made available to the ESA Tropisar project. The Biomass project at Jet Propulsion Laboratory (JPL) used this dataset for the evaluation of forest structure estimation from radar data.

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.

The aerial laser scanning (ALS) dataset, acquired on 20 October 2009, covers the experimental station Paracou in French Guiyana. More precisely, the dataset covers 9 plots totally (Paracou 4, Paracou 5, Paracou 7, Paracou 8, Paracou 9 - Paracou 12, and Paracou 14) and 4 plots partly (Paracou 3, Paracou 6, Paracou 13, and Paracou 15). The area includes exploited and non-exploited forest and Pinot palm.

The site Aimara is composed of four 3km-transects (20m wide). 4568 trees with dbh>=20cm have been recorded by Office national des forêts (ONF). Fauna inventories have been made by Office national de la chasse et de la faune sauvage (ONCFS) few days after. 534 under-storey plants have been recorded on 21 25m²-plots by Institut de recherche pour le développement (IRD). Soils have been described using 19 samples (1.20m depth max.). Laboratory analysis are available for one soil-profile.
